Problems solved by technology

[0005] Aiming at the problems existing in the prior art that due to the poor internal bonding of the thermal insulation board, cracks are prone to occur, resulting in poor overall thermal insulation and flame retardancy effects, the first purpose of the present invention is to provide a silica-based thermal insulation board. Isooctyltriethoxysilane and wood fiber, and make them play a good compound synergistic effect with each other to solve the above technical problems. It has good internal bonding and is not easy to crack during use , the overall has a good thermal insulation and flame retardant effect

Abstract

The invention discloses a silicolite heat insulation board and a preparation technology thereof, and relates to the technical field of heat insulation boards. The problems that due to the fact that the internal combination performance of the heat insulation board is poor, cracking is easily caused, and the integrated heat insulation and anti-flaming effects are poor are solved. The silicolite heatinsulation board is prepared from 80-160 kg.m<3> of an active mineral mixture, 10-30 kg / m<3> of an excitant, 10-30 kg / m<3> of a porous filler, 6-12 kg / m<3> of EPS particles, 3-5 kg / m<3> of waste gelatin powder, 0.4-0.8 kg / m<3> of wood fiber and 0.1-0.3 kg / m<3> of isooctyl triethoxy silane according to the ratio. The interior of the silicolite heat insulation board has the good combination, cracking is not likely to be caused in the using process, and the whole board has the good heat insulation and anti-flaming effects.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, more specifically, it relates to a silica rock thermal insulation board and a preparation process thereof. Background technique [0002] Building insulation is very important to improve living comfort and reduce social energy consumption. In the total building energy consumption, energy loss through wall heat transfer accounts for more than 60%. Therefore, excellent external wall insulation materials can save energy and reduce emissions. very important. The insulation board is a rigid foam plastic board made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, heated and mixed while injecting catalyst, and then extruded. [0003] Traditional external wall insulation is mainly divided into rubber powder polystyrene particle thermal insulation slurry, inorganic thermal insulation mortar, foamed cement board, EPS thermal insulation board extern...
