Problems solved by technology

[0003] The wrinkle paint in the traditional sense has: the size of the wrinkle pattern is not easy to control due to factors such as the level of construction personnel and the shape of the workpiece; due to the presence of tung oil in the existing product sink, the paint has poor weather resistance and is not suitable for outdoor products; construction technology Complicated and cumbersome process, resulting in inconsistent effects of the finished product; slow increase in coating film hardness, not suitable for assembly line operation, etc.

Abstract

The invention discloses a single-component acrylic acid modified wrinkle paint and a resin preparation method, and relates to the technical field of coatings. The specific method comprises the steps of under the catalysis of a modified phosphazene base, initiating phenyl-substituted cyclopropene dimethyl ester and isobornyl acrylate to carry out anionic copolymerization by using a prepared short-chain silicon initiator so as to prepare carboxyl-terminated acrylic resin; sequentially adding n-butyl acetate, ethyl acetate, carboxyl-terminated acrylic resin, soya oil acid, linoleic acid, pentaerythritol, terephthalic acid, benzoic acid and dibutyltin dilaurate into a reactor for a heating reaction, and preparing acrylic acid modified wrinkle resin; and mixing the acrylic acid modified wrinkle resin with each auxiliary agent, and adjusting the viscosity to obtain the single-component acrylic acid modified wrinkle paint. The prepared single-component acrylic acid modified wrinkle paint is clear in pattern, simple to construct and good in weather resistance and mechanical strength.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a single-component acrylic modified wrinkle paint and a resin preparation method. Background technique [0002] At present, the wrinkle paint used more on the market is a kind of decorative baking paint with phenolic resin and alkyd resin as the main film-forming substances. Manufactured from phenolic or alkyd resins, pigments, drying oils, catalysts and organic solvents. Through the adjustment of the pigment-base ratio, the amount of the flower-adjusting resin and the auxiliary alkyd resin, different patterns can be formed; through the adjustment of the diluent and drier, the pattern shape and film performance can be improved. [0003] The wrinkle paint in the traditional sense has: the size of the wrinkle pattern is not easy to control due to factors such as the level of construction personnel and the shape of the workpiece; due to the presence of tung oil in the existing pro...
