Problems solved by technology

However, this kind of board is prone to stress concentration, which is easy to damage and crack the board; the air permeability is poor, if the temperature difference between the two sides of the board is large, and the humidity is high, it is easy to condense, and the bond with the plastering mortar is not strong, and it is easy to fall off. Tiles fall off faster and more severely
Moreover, its service life is limited, so it is difficult to be used in occasions that require high strength, such as high-rise buildings.

Abstract

The invention discloses a building energy-saving heat preservation material and a preparing technology thereof. Polyphenyl fibers, ammonium aluminum carbonate hydroxide fibers and polypropylene fibers are added, long chains of fiber molecules are wound together and cross-linked into a network structure, and a fine structure similar to steel bars is formed so that after the heat preservation material is solidified, the cross-linked network structure can be solidified, and integral fastening can be achieved. The cross-linked net-shaped fibers can perform the effects of enhancing, cracking preventing and toughening after being foamed, stress concentration can be prevented, the dry shrinkage and cracking probability of the building energy-saving heat preservation material can be reduced, and the heat preservation effect and the flame retardance of the building energy-saving heat preservation material can be improved while the strength is improved; meanwhile, by means of the structure, more foaming holes can be allowed in the heat preservation material, and the heat preservation effect of the heat preservation material is enhanced.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to a building energy-saving thermal insulation material and a preparation process thereof. Background technique [0002] The current building insulation materials generally have a more popular meaning, and it is easy to understand that it is a board for building insulation. The current thermal insulation board is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, mixed with heat and injected with a catalyst, and then extruded and molded. It has moisture-proof and waterproof properties. , can reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. However, this kind of board is prone to stress concentration, which is easy to damage and crack the board; the air permeability is poor, if the temperature difference between the two sides of the board is lar...
