Abstract
The invention relates to a multi-layer multifunctional thermal insulation material and a preparation method thereof. The multi-layer multifunctional thermal insulation material has two appearance structures: a flat sheet structure or a round tubular structure; from a bottom layer to a surface layer, the flat sheet structure is sequentially provided with a base layer, a transition layer and a surface layer I or a surface layer II; from an inner layer to an outer layer, the round tubular structure is sequentially provided with a base layer, a transition layer and a surface layer I or a surface layer II; the base layer is prepared from a master batch, a foaming agent, an antioxidant, a catalyst, a crosslinking agent, an adsorbent, an emulsifier, a flame retardant and a color master batch, and mainly plays a thermal insulation role; the transition layer plays a role of connecting all the other layers, and has a certain thermal insulation function; the surface layer I has performance of blocking ultraviolet light and short wavelength visible light, so as to achieve an effect of resisting aging; the surface layer II has performance of low wear rate and high sliding friction coefficient, so as to achieve an effect of improving wear-resisting and anti-slide functions. The novel multi-layer multifunctional refrigerant thermal insulation material facilitates environment protection, has an obvious thermal insulation effect, is low-priced, and has an aging-resistant or wear resistant and anti-slide effects, thus enlarging the application scope of the material, and prolonging the service life of the material.
Description
technical field [0001] The invention relates to a multifunctional thermal insulation material, in particular to a multifunctional refrigerant thermal insulation material with a multi-layer structure and a preparation method thereof. Background technique [0002] Thermal insulation materials and their products are important factors affecting energy conservation and environmental protection in buildings and household appliances. Among them, refrigerant thermal insulation materials have a wide range of applications.
