Abstract

The invention relates to acrylic polyurethane finish paint as well as a preparation method and application thereof. The acrylic polyurethane finish paint comprises a paint vehicle and a curing agent, wherein the paint vehicle comprises the following components in parts by weight: 30-40 parts of high-solid polyether modified low-hydroxyl acrylic resin and 10-25 parts of teflon modified high-solid high-hydroxyl polyester resin; and the curing agent is prepared from 58 to 62 parts of a solvent-free aliphatic polyisocyanate tripolymer and 1 to 3 parts of a polyurethane dehydrating agent. The main purpose of the invention is to obtain the acrylic polyurethane finish paint with low TVOC residual quantity and excellent coating performance. The paint can meet the performance requirements and the environmental protection requirements of related product coating of customers, solves the problem that the existing solvent type product for the interior decoration of a railway vehicle has relatively strong pungent smell, and creates a comfortable and environment-friendly in-vehicle environment for passengers who go out by taking rail transit vehicles.

Description

[0001] This application is a divisional application with an application date of March 15, 2019, an application number of 201910197494.X, and an invention title of "Acrylic polyurethane topcoat for interior decoration of rail transit vehicles and its preparation method". technical field [0002] The invention relates to an acrylic polyurethane topcoat and its preparation method and application. Background technique [0003] In recent years, the overall development trend of the rail transit industry has been good, especially the subways and light rails in various cities have received great attention and support. With the improvement of people's living standards, there are new requirements for the safety and comfort of rail transit rides. More attention has been paid to environmental protection and health. In 2018, two technical standards related to coatings, Q / CR 546.1-2016 and Q / CR 581-2017 promulgated by the Railway Corporation, were gradually put into application, and the p...
