Abstract

The invention discloses a fire-proof thermal-insulation composite component and a manufacturing technology thereof. The component comprises a thermal-insulation substrate and fire-proof isolating belts, wherein grooves are formed in the upper surface and the lower surface of the thermal-insulation substrate in a staggered mode, the grooves are filled with the fire-proof isolating belts, material of the thermal-insulation substrate is one or more of C-level material, B1-level material and B2-level material, and material of the fire-proof isolating belts is A-level fire-proof material. The manufacturing technology comprises the steps that a, a mould is designed and used for forming the thermal-insulation substrate, and the mould is of a groove structure complementing the formed thermal-insulation substrate; b, raw material of the thermal-insulation substrate is injected into the mould, cooling mould releasing is achieved after one-time forming is conducted in a heating and foaming mode, and the formed thermal-insulation substrate with the grooves is obtained; c, the grooves of the formed thermal-insulation substrate with the grooves are filled with the A-level fire-proof material to form the fire-proof isolating belts, and namely the fire-proof thermal-insulation composite component is obtained. The fire-proof thermal-insulation composite component is convenient to produce and low in cost, and has a high fire safety level and good thermal-insulation heat-preservation performance.

Description

technical field [0001] The invention relates to the field of fire-proof and heat-insulating materials for buildings, in particular to a block-type fire-proof and heat-insulating composite member for building enclosure structures and a manufacturing process. Background technique [0002] Building energy conservation is a long-term basic national policy of the country. With the gradual improvement of the public's awareness of safety precautions, people have higher and higher requirements for the fire safety of thermal insulation materials while putting forward higher and higher requirements for building energy conservation. However, in the heat insulation materials currently on the market, there are organic heat insulation materials such as C-level (or B1 level or B2 level) good heat insulation performance but poor fire safety, and the performance of A-level inorganic heat insulation materials is just the opposite defect. , the contradiction between the two is difficult to re...
