Problems solved by technology

[0003] Traditional thermal insulation materials are fiber materials such as cotton and hemp, which have the advantages of being close to nature, environmentally friendly and comfortable, but their disadvantages limit their further development and utilization in furniture thermal insulation products, mainly because they are difficult to form, easy to deform, and have a general thermal insulation effect. Easy to absorb water and mold, poor mechanical properties and other problems
In known studies, various types of resin foams are used as insulation materials for furniture production, but such materials have poor mechanical strength, are easily deformed during use, have general aging resistance, are easy to pulverize and deteriorate, and have long service life and service life. discount

Abstract

The invention relates to the technical field of furniture material performance research, and discloses a pressure-resistant and deformation-resistant thermal insulation material for furniture production, which uses acrylonitrile and methacrylic acid as monomers, adds a prepared nucleation accelerator, and performs pre-polymerization to obtain a pre-polymerized material. The polymer is further foamed at high temperature to obtain the compression-resistant and anti-deformation thermal insulation material; the thermal conductivity of the prepared thermal insulation material is 0.018-0.020w / mk, the thermal conductivity will not increase due to moisture absorption, and the aging resistance and mechanical strength are excellent. The thermal insulation material has excellent properties such as light weight, insulation, shock resistance, compression resistance, corrosion resistance, water resistance, aging resistance, and stable chemical properties. It can be widely used in the insulation core layer of furniture and has excellent forming properties. It solves the dilemma of general thermal insulation performance of thermal insulation materials in the furniture field and many shortcomings in processing and application. In addition to improving the thermal insulation performance of materials, it has also achieved good results in other aspects.
