Problems solved by technology

Existing external wall insulation technologies have not escaped the circle of organic insulation materials in use, but on the basis of conventional materials and technologies, through the superposition of complex technologies, simple improvements to commonly used products have not fundamentally solved the problem of using non-combustible materials The problem of external wall insulation system
[0004] Organic thermal insulation materials have small thermal conductivity, good thermal insulation performance, and are easy to use, but their fireproof performance is poor. According to the current national requirements for thermal insulation materials, it is difficult to meet fireproof standards, and safety accidents continue in the process of application.
Inorganic thermal insulation materials have good fire resistance and meet the requirements of fire protection regulations, so there will be no fire safety accidents. However, inorganic materials have high density, poor thermal insulation performance, easy water absorption, and easily affected strength. The problem of safety fixation is difficult to solve

Embodiment 1

[0021] A preparation method of Class A fireproof insulation board for inorganic coated polystyrene particles. The preparation method includes four steps. In the first step, the surface of polystyrene particles is pretreated with 6-8 parts by weight of water-based white latex. In the second step, when the water-based white latex on the surface of the polystyrene particles is in a semi-dry state and has a certain viscosity, pour the slurry into the surface pretreated polystyrene particles. The third step is to use a stirring device to quickly stir in a short time, and the stirring is complete Then quickly pour the mixture into the mold box 1 (the mold box is a prior art, molded product), and in the fourth step, it is molded under a certain pressure. After curing, the large body is cut into insulation boards 2 of different thicknesses and sizes. .

Abstract

A preparation method of inorganic coated polyphenyl granule A-grade fireproof thermal insulation boards is discloses. The preparation method comprises four steps as follows: Step 1, pretreating the surface of polystyrene granules with 6-8 parts by weight of aqueous white latex; Step 2, pouring slurry to the surface-pretreated polystyrene granules when the aqueous white latex on the surface of the polystyrene granules is in a semi-dry state and has a certain viscosity; Step 3, rapidly stirring by a stirring device for a short time, and rapidly pouring the mixture into a mold box after the stirring is completed; and Step 4, carrying out compression molding under a certain pressure, curing, and cutting a large green body into thermal insulation boards with different thicknesses and sizes. The preparation method is applied to inorganic coated polyphenyl granule A-grade fireproof thermal insulation boards.

Description

Technical field [0001] The present invention relates to a preparation method of Class A fireproof and thermal insulation board with inorganic coated polyphenyl particles. Background technique [0002] External wall thermal insulation materials can be divided into two types: inorganic thermal insulation materials and organic thermal insulation materials according to their internal components. [0003] The fire class A is a material with no ignition point and has an insulating effect; the fire class B1 is a flame-retardant insulation material; the fire class B2 is a combustible insulation material, also called a flame retardant material. Most organic insulation materials are added with appropriate flame retardants. It is more common for EPS expanded polystyrene board and XPS extruded polystyrene board. This material has a low ignition point and releases a lot of harmful gases during the combustion process. None of the existing exterior wall thermal insulation technology has escaped ...
