1、Designation: D 6989 03Standard Practices forPreparation of Solvent and Water Based Ink ResinSolutions1This standard is issued under the fixed designation D 6989; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi
2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These practices describe laboratory procedures for pre-paring a solvent or water based ink resin solution in low boilingsolven
3、t or alkaline water using two types of lab equipment; (1)an industrial blender (Sections 3-7), and (2) a laboratory rollermill (Sections 8-12).NOTE 1ASTM Subcommittee D01.37 recommends using the indus-trial blender where possible.1.2 These practices use laboratory equipment generallyavailable in a n
4、ormal, well-equipped laboratory.1.3 These procedures are for use with ink resins intendedmainly for liquid (for example, flexographic and rotogravure)inks. The type of resins is typically, but not limited to, acrylicand styrene/acrylic copolymers, polyamides, polyesters, poly-vinylbutyral, and malea
5、ted/fumarated rosin esters.1.4 The typical low boiling solvents to be used includeethanol, isopropanol, n-propanol, ethyl acetate, isopropyl ac-etate, and n-propyl acetate. For water based ink resin solutions,water is used in combination with ammonium hydroxide oramines such as dimethylethanolamine,
6、 monoethanolamine, andtriethylamine.1.5 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the us
7、er of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definitions:2.1.1 cold cut, ndispersion of resin into solvent using highshear dispersion without external heating.2.1.2 compatibility, n
8、the ability of two or more differingsubstances to be mixed together without resultant kick-out orhaziness.2.1.3 dissolution, nthe point at which all resin completelydissolves in the solvent.2.1.4 incompatibility, nwhen a mixture of two or morediffering substances results in precipitation, kick-out,
9、or hazi-ness.2.1.5 solution, nresin and solvent form a clear, compat-ible, and homogeneous mixture.2.1.5.1 DiscussionIndustrial practice may use the term“solution” loosely to describe what may actually be a clear“dispersion.” For the sake of simplification, the terms solutionand dispersion have been
10、 used interchangeably in this practice.BLENDER3. Summary of Blender Practice3.1 Place required amount of resin and solvent in a blenderjar.3.2 Mix the resin-solvent mixture at high speed in a blenderuntil heat is developed by the high shear and the resin isdissolved into solution.3.3 The resulting r
11、esin solution can be used to measureparameters such as viscosity and solubility or compatibility ofa printing ink resin.4. Significance and Use of Blender Practice4.1 This practice provides a means of preparing resinsolutions by the “cold cut” method, modeling high-shearproduction dispersion techniq

Apparatus5.1 Balance or Scale, weighing to 60.1 g accuracy.5.2 Blender, with one quart vessel and cover, 115 alternat-ing current volts (VAC), 60 Hz, 840 W (preferably explosionproof).1These practices are under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings, Materials and

Sampling6.1 Solid resin should be flaked or crushed (typically to asize no larger than 6 mm2.6.2 The total mass of resin solids and solvent should beapproximately 800 g. The exact amount (separately) of re
