Problems solved by technology

[0005] At present, the decoration of building walls generally adopts traditional coatings. Most of the coatings are limited to the characteristics of high elasticity. They have poor fire resistance, low tensile strength, and general adhesion. They are generally only used for interior decoration. More and more attention is paid to the living environment, so the exterior decoration of buildings is also attracting more and more attention. Due to its poor fire resistance, it has low safety in case of accidental fire, etc.

Abstract

The invention discloses a building external wall fireproof coating and a preparation method. The building external wall fireproof coating is mainly prepared from the following raw materials in parts by weight: 20.0-26.0 parts of amino resin, 1.5-2.2 parts of titanium dioxide, 7.8-10.5 parts of polycarbonate, 6.4-8.1 parts of magnesium trisilicate, 7.3-9.4 parts of wollastonite, 3.3-5.2 parts of portland cement, 5.2-8.6 parts of fly ash, 1.2-1.6 parts of carrageenan and 2.4-3.6 parts of ethylene glycol. The coating has the advantages of good air permeability, high elasticity and cracking resistance, good weather resistance, excellent alkali resistance and water resistance, perfect flame retardance, no toxicity and environmental friendliness, low price and the like.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a fireproof coating for building exterior walls and a preparation method. Background technique [0002] The use of paint has been used in the progress of human society. The early knowledge of primitive paint was prepared by blending animal fats, plant extracts and various mineral raw materials. However, especially after the industrial revolution, the industrialization process accelerated. With the development of the current society, there are many types of coatings, and they have been widely used in all walks of life in modern society. Especially in terms of building exterior walls, people began to use coatings to decorate the exterior walls of buildings. [0003] The Chinese patent document of application publication number CN 104497680 A (application number 201410777097.7) discloses a nano-fireproof coating for exterior walls. The specific components and weight ratio are: wate...
