Water-based wall paint of shell powder

Abstract

Calcinated shell powder and raw shell powder are used in preparing water-based wall paint. Shell powder consumption is 10-100 % of solid matter and the rest part is stuffing and pigment. The paint is prepared by mixing shell powder with alkali resisting water soluble adhesive and corresponding assistant. The paint has high adhering force, good comprehensive performance of resisting washing, antiaging, etc, low cost, low toxicity, etc.

Description

Problems solved by technology

[0002] Existing wall coatings are divided into two categories: organic binder coatings and inorganic binder coatings. Although inorganic binder coatings have superior performance, they have certain difficulties in storage and construction and cannot be widely promoted.

A large number of organic binder coatings are mainly water-soluble latex binder coatings. Although the overall performance is good, the chemical synthesis of the base material is complicated and costly, and a large number of harmful and toxic chemical raw materials are used. During production, storage, Toxic and harmful gases are produced and released during use, causing harm to the human body

The second application is the less toxic polyvinyl alcohol organic binder coating, the production process is relatively simple, the cost is reduced, but its comprehensive performance such as adhesion, water resistance, natural erosion resistance, etc. also declines.
