Problems solved by technology

Disperse paraffin wax, microcrystalline wax and waxes evenly in water, and with the help of directional adsorption of emulsifier, emulsified wax can be obtained under the action of mechanical external force. To obtain stable emulsified wax, emulsification temperature, reaction time, The main influencing factors such as particle size, and related influencing factors such as emulsifier dosage, emulsifier addition method, cooling speed, stirring speed, etc. should also be considered. Since emulsifying wax is an emulsion...

Abstract

The invention relates to the fields of dye, coating and adhesive, in particular to a release layer material for alumite, and provides an environment-friendly emulsified wax release material for alumite and a preparation method thereof. The emulsified wax has low influence on the environment, low harmful substance volatilization and low manufacturing cost; the problems that the emulsified wax becomes viscous during use, the wax coated to a base film has poor uniformity and the stripping effect of the emulsified wax is affected by unstable coating amount of unit area are not caused; and the alumite manufactured by using the emulsified wax release material has good printing property, uniform film formation and moderate stripping in large-batch production, and does not cause the condition of non-uniform tightness. The invention adopts the following technical means that: the emulsified wax release material for the alumite comprises the following components in part by weight: 25 to 50 parts of water, 40 to 60 parts of cosolvent, 2 to 7 parts of aqueous emulsifier and 1 to 8 parts of wax.

Description

technical field [0001] The invention relates to the fields of dyes, coatings and adhesives, and more specifically relates to a release layer material of anodized aluminum. Background technique [0002] In the production of anodized aluminum, the transfer coating is mostly organic solvent type, volatile organic compounds will cause serious environmental pollution, and the use of organic solvents will increase the cost of production. [0003] For example, the patent document whose application number is 200610116782.0 (a release agent for anodized aluminum coating and its preparation method) discloses a formula and a preparation method of an anodized aluminum coating release agent. One of its main features is to use Toluene and methyl ethyl ketone are used as solvents, and substances such as toluene and methyl ethyl ketone are toxic to a certain extent. When used in products, they will cause organic residues and are harmful to human health. [0004] In order to meet the curren...
