Problems solved by technology

However, its materials generally have the following disadvantages: 1. The efficiency of blocking heat radiation is not high; 2. Poor flame retardancy; 3. Too much dependence on metal plates
At present, the flame retardant effect is mainly achieved by adding a flame retardant to the insulation material, but with the addition of the flame retardant, the mechanical strength of the airgel insulation material will gradually decrease, and its thermal conductivity will gradually increase. will gradually decrease
[0004] At present, the use of non-metallic plates is becoming more and more extensive. The output of non-metallic plates is large and the consumption is large. Most non-metallic plates do not have the function of flame retardancy. In some special occasions, there is a demand for materials with flame-retardant functions. If you use general non-metallic plates, there will be safety hazards, which may cause a lot of economic losses and even personal safety.

Abstract

The invention discloses a non-metal heat-insulation flame-retardant multifunctional plate which comprises a base material plate, heat preservation layers and heat-insulation flame-retardant layers. The heat preservation layers are arranged on the upper face and the lower face of the base material plate. The heat insulation flame-retardant layer is arranged on the outer side of each heat preservation layer; the base material plate is a wood base material; the heat preservation layers are made of polyurethane foam or rock wool or expanded perlite, and meanwhile, the outer side of each heat-insulation flame-retardant layer is further coated with a heat-insulation flame-retardant coating. The heat-insulation flame-retardant coating is composed of modified nano silicon carbide, diatomite, silicon dioxide aerogel, lauryl sodium sulfate, diisocyanate, a coalescing agent and a flame retardant. In the coating, the polarity of the nano silicon carbide is improved, the possibility of agglomeration of the modified silicon carbide is obviously reduced, and meanwhile, the dielectric property of a coating layer is improved.

Description

technical field [0001] The invention relates to the field of heat-insulating and flame-retardant materials, in particular to a non-metallic heat-insulating and flame-retardant multifunctional board. Background technique [0002] With the rapid development of the national economy and the emergence of various new technologies and new industries, the demand for engineering materials with various properties is becoming more and more extensive. A single metal material is either limited by natural resources, or due to insufficient comprehensive performance, its application fields are greatly limited. In this case, the development, production and application of non-metallic materials are increasingly showing their important status. [0003] In recent years, the global energy crisis has put forward a new urgent demand for thermal insulation materials. In the field of high temperature insulation, industry, construction, transportation, fire protection and other fields, there is als...
