Composite building board and manufacturing method thereof

Abstract

The invention discloses a composite building board and a manufacturing method thereof, wherein the composite building board is provided with a core board, the core board is a polystyrene foam board, and the outer surface of the core board is compounded with a glass fiber reinforced magnesium oxychloride concrete layer with a thickness of between 3 and 5mm. Glass fiber reinforced magnesium oxychloride concrete comprises glass chopped strand and pulverized fuel ash, is modified by a modifying agent, has a reasonable formulation, and does not halogenate, generate cold frost or deflect; and the manufactured composite building board product has higher strength and lighter weight, and can be used as a wall body material and a roof material to build livestock and poultry houses, simple houses and prefabricated houses. The livestock and poultry houses, the simple houses and the prefabricated houses which are built by the composite building board have the advantages of good thermal insulation property, higher integral strength, convenient construction and lower manufacturing cost.

Description

technical field [0001] The invention relates to a building board and a manufacturing method thereof, in particular to a composite layer of the building board and a gelling material between the composite layers. Background technique [0002] In the intensive raising of livestock and poultry, the livestock and poultry house used generally has a larger area. The livestock and poultry house requires high overall strength, good cold and heat preservation performance, convenient construction and low cost. In the prior art, the livestock and poultry house used when intensively raising livestock and poultry has a brick-concrete structure or a plastic greenhouse structure. The building materials of brick-concrete structure livestock and poultry houses are bricks and cement, and the building materials of plastic greenhouse structure livestock and poultry houses are mainly rigid material skeleton and plastic film. When the above-mentioned building materials are used to build livestoc...

AI Technical Summary

Problems solved by technology

When the above-mentioned building materials are used to build livestock and poultry houses, the overall strength of the brick-concrete structure of the livestock and poultry houses is higher, but the cost is higher. Due to the high thermal conductivity of the brick-concrete structure building materials, the cold and heat preservation performance of the livestock and poultry houses is not very good. , the construction is not very convenient; the cost of livestock and poultry houses with plastic greenhouse structure is relatively low, and the construction is more convenient, but the overall strength of livestock and poultry houses is low. , there is no good building material for livestock and poultry houses
