Slow-drying type batch-scraping sand wall paint and preparation method thereof

Abstract

The invention relates to a slow-drying type batch-scraping sand wall paint and a preparation method thereof. The paint is composed of the following raw materials by the mass percentage: 22 wt%-27 wt%of deionized water; 0.2 wt%-0.3 wt% of a preservative, 0.2 wt%-0.3 wt% of hydroxyethyl cellulose, 0.1 wt%-0.2 wt% of a pH adjusting agent, 2 wt%-5 wt% of thermosetting super absorbent resin, 0.2 wt%-0.3 wt% of a wetting agent, 1 wt%-1.5 wt% of propylene glycol, 1 wt%-1.2 wt% of a slow drying coalescing agent, 0.1 wt%-0.2 wt% of wood fiber, 0.3 wt%-0.5 wt% of titanium dioxide, 0.6 wt%-1.5 wt% of diatomite, 10 wt%-15 wt% of a styrene-acrylic emulsion, 0.6 wt%-0.8 wt% of a water-based slow drying agent, 1 wt%-1.2 wt% of an defoaming agent, 50 wt%-55 wt% of water-absorbing stone powder and 0.1 wt%-0.3 wt% of a polyurethane thickening leveling agent. The slow-drying type batch-scraping sand wall paint provided by the invention has the advantages of long drying time, long construction opening time, excellent sand wall paint leveling property, no laitance, less floating and the like.

Description

Technical field [0001] The invention belongs to the field of environmental protection coatings, and specifically relates to a slow-drying batch sand scraping wall paint and a preparation method thereof. Background technique [0002] Sand wall paint is produced with water-based acrylic adhesive and other additives, which is a kind of elastic texture paint. Sand wall paint has excellent weather resistance. Its characteristics of resistance to ultraviolet rays and aging, so it can make the wall new for a long time. Sand wall paint is specially designed with a structure rich in viscosity, which is extremely flexible and can bridge small wall cracks. Not only that, the sand wall paint is resistant to washing, and the thick paste coating and its texture can protect the building and decorate the sand wall. [0003] Sand wall paint construction methods are divided into batch scraping and spraying. Among them, batch scraping construction is particularly common. Due to the high summer te...
