Problems solved by technology

[0003] The common types are: XPS Disadvantages: XPS board itself has high strength, which makes the board more brittle and not easy to bend. The temperature difference on both sides of the board is large, and the humidity is high and it is easy to condense; because the surface of the board is smooth, it needs interface treatment and roughening during construction
Disadvantages of polyurethane insulation board: the formula and ratio of insulation board are messy and unstable, which leads to poor physical stability of the board and poor insulation effect; the construction of spraying has not been solved, and it is difficult to guarantee the quality of the project
[0004] Disadvantages of phenolic insulation board: In order to increase its compressive and tensile strength, a layer of inorganic board or mesh cloth is generally pasted on both sides; the operating temperature is -60°C to 150°C, and it cannot be used at high temperatures. Resistance to high temperature disparity, the high temperature mentioned here will never exceed 200°C, and 200°C is not considered a high temperature. If it exceeds, there must be highly toxic smoke
Organic matter cannot be resistant to aging, ultraviolet rays and other rays will act for a long time, and the phenolic insulation board will lose its function and shorten its life

Abstract

The invention provides a high-strength fire-proofing insulating plate for construction. The insulating plate is prepared from the following raw materials in parts by weight: 20-25 parts of boric sludge, 16-20 parts of palygorskite, 6-8 parts of dickite, 12-15 parts of baddeleyite, 25-30 parts of gypsum powder, 2-3 parts of p-hydroxybenzenesulfonic acid, 3-4 parts of benzene sulfinic acid sodium salt, 5-7 parts of polyacrylamide, 4-6 parts of high-substituted hydroxyproxyl cellulose, 9-13 parts of lignocellulose and 30-40 parts of water. The high-strength fire-proofing insulating plate for construction has the characteristics of high tensile strength, temperature preservation and heat insulation, good fire-proofing performance, corrosion resistance, damp resistance and the like, and is very suitable for construction separators.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a high-strength fire-proof insulation board for building and a preparation method thereof. Background technique [0002] Insulation board is easy to understand, it is the board used for building insulation. Insulation board is a rigid foam board made of polystyrene resin as raw material plus other raw and auxiliary materials and poly inclusions. It is heated and mixed while injecting catalysts, and then extruded and molded. It has moisture-proof and waterproof properties. It can reduce the thickness of the building envelope, thereby increasing the indoor use area. [0003] Common types are: the disadvantages of XPS: the strength of XPS board itself is relatively high, which makes the board more brittle and not easy to bend. The stress on the board is concentrated when the stress is present on the board, which is easy to damage and crack the board; it has poor air ...
