Problems solved by technology

However, although the paint film of this wrinkle paint has good water resistance, high gloss and hardness, pure benzene is used as a diluent in the synthesis process of the phenolic wrinkle resin, which has certain toxicity; Refining is generally heated by open fire, which poses a great safety hazard, and the resin is composed of multiple hard resins that need to be refined by open fire at high temperature (290°C). The process is complex, costly, energy-consuming, and dangerous. According to national regulations, Tianjin Safety Supervision Bureau requires chemical companies within the outer ring road to prohibit the use of open flame heating to produce various resins, and the process must be changed, otherwise the production and sales of such products will be stopped
Therefore, it is of great practical significance to seek a wrinkle paint with good water resistance and high gloss to overcome the safety hazards existing in the production process of the existing wrinkle paint.

Abstract

The invention provides alcohol acid ripple finish and a preparation method thereof. The alcohol acid ripple finish comprises, by weight, 50-60 parts of alcohol acid ripple resin (having solid content of 60+ / -3wt%), 5-10 parts of polymerized oil pattern-adjustment resin, 2-3 parts of carbon black, 20-35 parts of light calcium, 0.5-1.5 parts of bentonite HFGEL-40A, 1-2.5 parts of lead naphthenate having the content of 10%, 2-3.5% of cobalt naphthenate having the content of 4%, 0.1-0.3 parts of an anti-skinning agent and 5-10 parts of toluene. The anti-skinning agent is methyl ethyl ketoxime, butyraldehyde oxime or cyclohexanone-oxime and is obtained by mixing. The film of the alcohol acid ripple finish has excellent characters, realizes a flexible change of ripple patterns according to user demands and can be prepared by a simple method.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an alkyd wrinkle paint and a preparation method thereof. Background technique [0002] Most of the wrinkle paints currently used in the market are phenolic wrinkle paints based on phenolic wrinkle resin. The surface of the wrinkle paint looks like the hammer pattern left by hammering iron plates. It is used as a decorative coating on the surface of various metal products such as various medical devices, instruments, and instruments. However, although the paint film of this wrinkle paint has good water resistance, high gloss and hardness, pure benzene is used as a diluent in the synthesis process of the phenolic wrinkle resin, which has certain toxicity; Refining is generally heated by open fire, which poses a great safety hazard, and the resin is composed of multiple hard resins that need to be refined by open fire at high temperature (290°C). The process is complex,...
