Long fiber glass reinforced hydrophobic perlite thermal baffle for buildings and method for manufacturing same

Abstract

The invention relates to a novel fireproofing and heat preservation material for buildings, in particular to a long fiber glass reinforced hydrophobic perlite thermal baffle for the buildings. The long fiber glass reinforced hydrophobic perlite thermal baffle for the buildings is characterized by comprising the following raw materials in percentage by weight: 25 to 50 percent of expanded perlite, 30 to 55 percent of paste or white cement, 5 to 15 percent of filler, 0 to 10 percent of silicate cotton, 0 to 3 percent of retarding agent, 1 to 5 percent of inflating medium, 0.5 to 5 percent of polyaluminum chloride and 1 to 3 percent of water repellent. Due to good fire resistance, good heat insulation and preservation property, mechanical property and construction property, the product of the invention meets the fire resisting and energy saving requirements of the modern buildings, belongs to an environmentally-friendly material and has no pollution to the environment.

Description

Technical field [0001] The invention relates to a new type of building fireproof insulation material, in particular to a filament glass fiber reinforced hydrophobic perlite building insulation board. The product of the invention is used for the fire protection of steel structure buildings and the fire protection of roofs, exterior walls, bottoms, columns, and fire protection of fire doors, fire partition walls and other parts of the construction industry. Background technique [0002] Building energy conservation is the main content of the implementation of the national environmental protection and energy conservation policy, and an important part of the implementation of the sustainable development of the national economy. Under the guidance of a series of national energy-saving policies, regulations, standards and mandatory provisions, the energy-saving work of residential construction in my country has been continuously deepened, and energy-saving standards have been continuou...

Problems solved by technology

[0009] Among the commonly used exterior wall insulation materials, organic insulation materials are flammable, and are easy to form combustion channels in the event of a fire. They do not meet the fire protection requirements of buildings and will eventually be eliminated; inorganic insulation materials are non-combustible materials, which meet the requirements of exterior wall insulation materials. The development trend of the country and the requirements of relevant national regulations and policies, but the thermal insulation performance is quite different. The commonly used mineral wool and glass wool products have low bulk density and low compressive strength, which limits its application in external wall thermal insulation construction; hydrophobic perlite The thermal conductivity of the plate is low, but this type of product is fragile and the overall strength is not good; moreover, from the current production process of various inorganic thermal insulation materials, most of them adopt discontinuous production, and the production efficiency is low
