Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International orga

    18、nizations, governmental and non-governmental, in liaison with ISO, also take patt in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of elecrotechnical standardization. Intemational Standards are drafted in accordance with the rules given in

    19、 the ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility tha

    22、ational Standard gives an overview of the different types of phenolic resin used in the manufacture of thermosetting plastics and a summary of available test methods. Clause 3 defines terms relating to the chemical structure of phenolic resins, their physical state and their degree of condensation o

    23、r polycondensation. Clause 4 gives a summary of test methods. These methods apply to the determination of properties which are relevant to the production, processing and use of phenolic resins as described in clause 3. The user should select from the tests those that are appropriate for a particular

    24、 application. For a given method, only the standard(s) listed may be used. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisi

    25、ons of, this publication do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the normative document indicated below. For undated references, the latest edition of the normative document

    26、 referred to applies. Members of IS0 and IEC maintain registers of currently valid International Standards. IS0 472:1999, Plastics - Vocabuhy. 3 Basis of classification of phenolic resins This clause defines terms relating to the chemical structure of phenolic resins, their physical state and their

    27、degree of condensation or polycondensation for classification purposes in the manufacturing and processing of the resins. The definitions apply to all fields of application of phenolic resins in plastics (see also related definitions in IS0 472). 3.1 General 3.1.1 a) b) The term “phenolic resins“ as

    28、 used in this International Standard refers to synthetic resins or modified products obtained by condensation of phenol with aldehydes, particularly formaldehyde; products of the addition of phenols to unsaturated compounds (for example acetylene, terpenes and natural resins). 1) Strictly speaking,

    29、these resins are not what are normally regarded as resins for the production of plastics. They are used particularly in certain surface coatings. 1 STD=BSI BS EN IS0 30082-ENGL 2000 = lb24bb9 08bL775 991 EN IS0 10082:1999 NOTE the modifying medium are not regarded as phenolic resins. Resins in which

    30、 the original properties are so changed by the modification that they resemble more closely those of 3.1.2 Phenolic resins may be classified in a number of ways, such as by a) the type of raw material (see 3.2); b) the type of resin produced (see 3.3); c) the type of modification (see 3.3.2); d) the

    31、 physical form of the commercial product (see 3.4); e) the degree of condensation (see 3.5); i) the type of catalyst used (see 3.6.1); g) the type of hardener used (see 3.6.2). 3.2 Raw materials 3.2.1 Phenols Besides unsubstituted phenol, derivatives of phenol are used for the manufacture of phenoli

    32、c resins. These include cresols, xylenols and other alkylphenols (for example p-fert-butylphenol, p-fed-octylphenol and p-fert-nonylphenol), arylphenols (for example phenylphenol and naphthols) and divalent phenols (such as resorcinol and bisphenol A). 3.2.2 Aldehydes The most important aldehyde com

    33、ponent is formaldehyde, which is used in various forms, including aqueous solution and solid paraformaldehyde, and also as compounds which give rise to formaldehyde. Other aldehydes (for example acetaldehyde, acrolein, benzaldehyde and furfural) are employed to a more limited extent, as also are ket

    34、ones. 3.3 Types of phenolic resin 3.3.1 Unmodified phenolic resins Unmodified phenolic resins are produced by condensation reactions of phenols with an aldehyde. Depending on factors such as the volume and molar ratio of the raw materials, the reaction conditions and the catalysts employed, two diff

    35、erent classes of product are obtained: novolaks and resols. 3.3.1.1 Novolaks (two-step) Novolaks are non-self-curing, soluble, fusible phenolic resins that remain stable when stored. The phenol nuclei are linked primarily by methylene bridges. Novolaks can be made to react further and crosslink by t

    36、he addition of hardeners (see 3.6.2); heating is also usually necessary. See also novolak in IS0 472. . 3.3.1.2 Resols (one-step) Resols are soluble, fusible phenolic resins which, in contrast to novolaks, contain methylol groups and methylene- ether and sometimes also methylene-amine bridges. Resol

    37、s are self-curing: they crosslink to give insoluble products when heated and/or mixed with catalysts, without addition of further reaction components. Resols are perishable and can be stored for a limited time only. See also resol in IS0 472. 2 STD-BSI BS EN IS0 10082-ENGL 2000 Lb24bb9 OAb177b 828 E

    38、N IS0 10082:1999 3.3.2 Modified phenolic resins Phenolic resins can be modified by chemical reaction of the methylol or the phenolic hydroxyl groups and/or by physical dispersion in the modifying agent. Such modified phenolic resins can be either self-curing or non-self- curing, depending on their s

    39、tructure. 3.3.3 Phenolic addition resins Phenolic resins can also be produced without condensation with formaldehyde by reaction of phenol with unsaturated hydrocarbons. Examples of these are phenoVacetylene and phenol/terpene resins, which are not always self-curing. 3.4 Forms of commercial product

    40、 Phenolic resins are manufactured and used in various forms, such as a) liquids; b) solids, as pelletized, flake, granular or finely powdered products; c) solutions or dispersions in water and/or organic solvents. A so-called “aqueous solution“ (it is not a real aqueous solution) is one that has a w

    41、ater content of more than 5 % (m/m) and an organic-solvent content of less than 5 Yo (m/m) (free phenol is not counted as organic solvent). A solvent-containing phenolic resin solution is one that has more than 5 Yo (m/m) of organic solvents. 3.5 Degree of condensation Phenolic resins can be crossli

    42、nked by the use of heat and/or hardeners and/or catalysts. They pass through the following transitional stages of condensation: - A-stage: starting state (resol or novolak); liquid or fusible, and soluble in alcohol and acetone; - B-stage: intermediate state (resitol); infusible, but still mouldable

    43、 with heat and capable of swelling in alcohol or acetone; - C-stage; final state (resite); infusible, and insoluble in alcohol or acetone. See also A-stage, B-stage, C-stage, resite and resitol in IS0 472. 3.6 Catalysts and hardeners 3.6.1 Catalysts Catalysts accelerate the crosslinking reaction. Bo

    44、th acid and basic compounds are suitable for this purpose. 3.6.2 Hardeners (crosslinking agents) Formaldehyde, or compounds that release formaldehyde, for example hexamethylenetetramine (hexamine), can be used as hardeners. Resols and isocyanates can also be used as hardeners. Hardeners are generall

    45、y added only to non-self-curing phenolic resins and cure by chemical reaction (three-dimensional crosslinking). 3 4 Test methods 4.1 Numerical list IS0 60: 1 977, Plastics - Determination of apparent density of material that can be poured from a specified funnel.
