Problems solved by technology

[0004] However, the inventor found that the mechanical properties of the above-mentioned sound insulation panels are poor, and when the temperature is higher than 150°C, heat radiation becomes the main way of heat transfer. When the ambient temperature of the sound insulation panels is higher than 150°C, the heating The infrared radiant energy generated will directly penetrate the sound insulation board, resulting in a significant decrease in its thermal insulation performance

Abstract

The invention discloses a high-sound-insulation epoxy resin building material for architecture and relates to the technical field of building materials. According to the epoxy resin building material,a thermal radiation resisting layer, a sound insulating layer and a base layer structure which are subjected to hot-press forming from outside to inside are adopted, and three layer structures all adopt bisphenol A type epoxy resin as adhesives; in the sound insulating layer, carboxymethyl chitosan / sodium alginate is added to coat silicon dioxide aerogel microspheres, ingredients of silicon dioxide aerogel can be controllably released, thermal radiation is effectively partitioned, and a relatively small coefficient of thermal conductivity is kept; meanwhile, sound insulating and mechanical properties are excellent, the thermal radiation resisting layer can reinforce thermal radiation resistance through silicon dioxide aerogel micropowder, and a variety of fillers absorb noises of different frequencies. The epoxy resin building material disclosed by the invention is remarkable in heat-resisting, flame-retarding and sound-insulating effects and can be used in high-temperature environments of 150 DEG C to 300 DEG C.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a high-sound-insulation epoxy resin building material for buildings. Background technique [0002] Epoxy board is also called insulation board, epoxy board, 3240 epoxy board. Epoxy resin molecules are organic polymer compounds containing two or more epoxy groups, and the epoxy groups can be located at the end, middle or ring structure of the molecular chain. Due to the high reactivity of the epoxy group, it can cross-link with different types of curing agents to form an insoluble and infusible high polymer with a three-way network structure, which has the advantages of convenient curing, strong adhesion and low shrinkage. , Excellent mechanical properties. [0003] Building materials with sound insulation effect can be divided into sound insulation of buildings and sound insulation of structures, and not all frequencies of sound can be blocked. When the sound is clos...
