Abstract

The invention discloses water-based tearable film sol resin for vehicle paint protection. The water-based tearable film sol resin is prepared from the following components in parts by weight: 50-70 parts of water-based polyurethane resin, 5-15 parts of a water-based acrylic emulsion, 5-15 parts of modified silica sol, 1-3 parts of a leveling thickening agent, 1-3 parts of a wetting dispersant, 2-5parts of a coalescing agent, 1-3 parts of a stripping promoting agent, 0-1 part of a defoaming agent, and 10-20 parts of water. According to the invention, the waterborne tearable film adopts waterborne polyurethane resin as a matrix, wherein the toughness and hardness of the film can be enhanced respectively by the water-based acrylic emulsion and the modified silica sol, so that by means of theformula, the prepared water-based tearable film for car paint protection has the characteristics of good toughness, high glossiness, transparency, wear resistance, excellent protection performance, adjustable adhesion, adjustable hardness and the like. The product can effectively prevent car paint from being scratched and damaged, adopts water as a solvent, and is environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of car paint spray film, in particular to a water-based tearable film sol resin used for car paint protection, its preparation method and application. Background technique [0002] In recent years, thanks to the rapid economic development and the continuous improvement of road construction, China's car purchases have continued to grow in the past ten years. However, with the increase in car ownership, the problems of scratches and original car paint wear and aging in the process of car use are The majority of car owners are worried. At present, the traditional paint spraying and whole car filming methods used in the maintenance market cannot completely solve the above pain points. On the contrary, there are side effects of intrusion and corrosion of the original car paint. The degumming of the traditional full-vehicle film, the chapping caused by ultraviolet radiation, and the residue during replacement wil...
