Light flame-retardant thermal insulation board and manufacturing method thereof

Abstract

The invention relates to a light flame-retardant thermal insulation board and a manufacturing method thereof, and belongs to the technical field of composite materials and novel chemical building materials. The insulation board is composed of a core layer, a middle layer and a shell layer; the core layer, the middle layer and the shell layer are independently extruded by three extruders to form acore layer material flow, a middle layer material flow and a shell layer material flow respectively; the core-layer material flow, the middle-layer material flow and the shell-layer material flow converge in the mouth mold, the core-layer material flow is located at the innermost part, the middle-layer material flow wraps the periphery of the core-layer material flow, the shell-layer material flowwraps the periphery of the middle-layer material flow to form a mixed material flow, and the mixed material flow is extruded in the mouth mold to obtain the light flame-retardant thermal-insulation board. The invention is convenient to produce and manufacture, high in production continuity and high in production efficiency; the insulation board is small in density, light in weight, flame-retardant, good in heat preservation effect, waterproof, corrosion-resistant, mothproof, free of cracking, aging and deformation, free of color difference, free of paint falling in the using process, free ofmoisture absorption and moisture regaining and the like.

Description

technical field [0001] The invention relates to a light-weight flame-retardant thermal insulation board and a manufacturing method thereof, belonging to the technical field of composite materials and new chemical building materials. Background technique [0002] Various boards are often used in homes, offices, conference rooms, laboratories and other occasions. The boards commonly used in the market mainly include wood boards, metal boards, plastic boards, veneer particle boards, plywood boards, gypsum boards and stone boards.

AI Technical Summary

Problems solved by technology

Among them, wooden boards have good natural affinity, light weight, convenient processing, and easy installation, etc., but there are defects such as easy moths, perishable, poor water resistance, shrinkage and cracking, and no flame retardancy; metal boards have high strength. , high rigidity, strong and durable, but bulky, monotonous color, poor decoration, poor insulation effect, etc.; Inflammable, and the production of plastic boards wastes non-renewable fossil resources, etc.; veneer particle boards are cheap and easy to process, but the part of the particleboard body is easy to absorb water, swell, deform, and has low structural strength and is easy to break. Once these phenomena occur, It often affects the appearance and use effect of the board, and may even cause the whole board to be unusable and non-flame retardant; plywood is cheap and easy to use, but it does not retain heat and is not flame retardant, and it generally contains formaldehyde or other volatile organic compounds , will cause indoor pollution during use; gypsum boards are light in weight, easy to transport and install, but low in strength, easy to break, easy to absorb moisture, etc.; stone boards have high rigidity, good wear resistance, and good stability , but brittle, difficult to process, poor decoration, poor heat preservation effect, etc.
