Wear-resisting anti-oxidation ultraviolet light curing exterior wall coating and preparation method thereof

Abstract

The invention discloses wear-resisting anti-oxidation ultraviolet light curing exterior wall coating. The wear-resisting anti-oxidation ultraviolet light curing exterior wall coating is characterized by being prepared from the following raw materials in parts by weight: 30-35 parts of polyester acrylate, 19-23 parts of amino acrylate, 13-14 parts of trimethylolpropane triacrylate, 2-3 parts of lignocellulose, 4-5 parts of light initiator 1173, 10-13 parts of pentaerythritol tetraacrylate, 5-7 parts of phenyl glycidyl ether, 4-6 parts of acetic ether, 1-2 parts of cobalt naphthenate, 1-2 parts of accelerant TMTD (tetramethyl thiuram disulfide), 1-2 parts of grape seed oil, 5-7 parts of monazite powder, 2-3 parts of chromium trioxide, 3-5 parts of magnesium silicate and 4-5 parts of addtivie. The wear-resisting anti-oxidation ultraviolet light curing exterior wall coating has the advantages that due to addition of the grape seed oil which is a natural antioxidant ingredient, the ageing-resistance performance of the coating can be improved, and the coating is safe and non-toxic; due to addition of the monazite, the hardness of a paint film is improved, and the paint film has good wear resistance; and due to addition of the additive, the coating has good leveling property, hardness and very strong adhesive force, is fast in curing speed, wear-resistant and can be used as the exterior wall coating.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a wear-resistant and oxidation-resistant ultraviolet light curing exterior wall paint and a preparation method thereof. Background technique [0002] UV curing coatings have become a relatively mature technology, especially with the improvement of people's awareness of environmental protection, production and researchers pay more attention to the development and application of UV curing coatings. UV curing coating is a kind of green and environment-friendly coating, which fully complies with the "4E" principle. Generally, the energy consumption of UV curing is 1 / 5 of that of thermal curing, and UV curing coating contains less volatile components and less pollution. It is most attractive to researchers. And the developer's advantage is that UV curing coatings can reduce raw material consumption, which is beneficial to reduce economic costs. [0003] The current UV curin...

Problems solved by technology

[0003] The current UV curing materials are various, but there are still some problems to varying degrees. The existing UV curing coatings have a large shrinkage rate after photocuring and produce shrinkage stress, resulting in brittleness of the coating film, adhesion and impact resistance. Poor, poor flexibility and low hardness of the coating film, no corrosion resistance, easy yellowing and aging, etc. These series of problems need to be continuously improved for different purposes, reduce production costs, and expand uses
