Acrylic ester modified high-weatherability paint and preparation thereof

Abstract

The invention relates to paint for a surface coating of a section, in particular to acrylic ester modified high weather resistance paint and a preparation method thereof. The paint consists of the following raw materials in weight portion: 16 to 70 portions of matrix resin, 10 to 55 portions of active diluent, 9 to 50 portions of solvent, 0.3 to 0.8 portion of foam suppressor, 4 to 10 portions of light initiator, 3.5 to 8 portions of anti-wear additive, 0.4 to 1 portion of flatting agent, 0.4 to 1.2 portions of dispersing agent, and proper amount of pigment. The paint improves the quality of a PVC plastic colorful section and enlarges the application range of the material. The method reasonably prepares the acrylic ester modified high weather resistance paint used on the surface of the section by using a unique acrylic ester modified high weather resistance paint formulation. The invention provides the acrylic ester modified high weather resistance paint with new formulation to solve the problems of poor weather resisting property of the product and poor adhesive force of the paint during stamping after the product is stamped. The application of the paint successfully realizes high quality and high taste of the colorful section, and realizes technical renovation and great-leap-forward development of the industry of PVC colorful section.

Description

technical field [0001] The invention relates to a paint for profile surface coating, in particular to an acrylate-modified high-weather-resistant paint and a preparation method thereof. Background technique [0002] Steel-plastic co-extrusion doors and windows is a new technology and new product, which only entered the market in March this year, but the colored profiles made by co-extrusion technology, the color layer is easy to fall off and fade, and it will turn gray and dark after a period of ultraviolet light exposure; In addition, after the colored layer of the colored profile falls off, it will cause uneven accumulation of light and heat, resulting in the exacerbation of the molecular displacement of each component of the material after the colored profile is subjected to light and heat, the mechanical properties of the material are significantly reduced, and the service life is significantly reduced.
