Transparent heat-insulating polystyrene composite material

Abstract

The invention discloses a transparent heat-insulating polystyrene composite material. The transparent heat-insulating polystyrene composite material comprises the following raw materials in parts by weight: 70 to 100 parts of polystyrene, 10 to 30 parts of polyterpene phenolic resin, 3 to 7 parts of K resin, 5 to 10 parts of polyvinyl butyral, 1 to 5 parts of tert-butyl peroxybenzoate, 1 to 3 parts of resorcinol bis(diphenyl phosphate), 5 to 10 parts of hydroxy propyl distarch phosphate, 1 to 3 parts of hydroxyl silicone oil, 0.5 to 2 parts of sodium polyacrylate, 100 to 200 parts of heat-insulating filler, 0.5 to 1.5 parts of an antioxidant and 0.5 to 1.5 parts of a light stabilizer; the heat-insulating filler comprises modified transparent powder, hollow nano-silicon dioxide microspheres and polyanionic cellulose which are in the mass ratio of 2-4:1-2:1. Through a plurality of experiments, the transparent heat-insulating polystyrene composite material has good heat insulating performance, simultaneously can maintain good fire resistance, transparency and corrosion resistance, and is convenient to process and plasticize; the application range of the heat-insulating material is further enlarged.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a polystyrene transparent thermal insulation composite material. Background technique [0002] The thermal insulation material can collect excess heat and release it in a timely and stable manner, with small gradient changes, which can effectively reduce the loss. The room temperature can be trended and the winter heat preservation can play a balancing role. Thermal insulation materials can be divided into: organic thermal insulation materials: such as straw, rice husk, sugarcane fiber, wood chips, wood shavings, wood fiber and their products. Large, easy to rot after damp, easy to decompose or burn at high temperature; inorganic heat insulation materials: mineral wool, expanded vermiculite, expanded perlite, diatomite gypsum, glass fiber, rock wool, aerated concrete, foam concrete And its products, etc. These materials do not rot and have good high temperat...

Problems solved by technology

Thermal insulation materials can be divided into: organic thermal insulation materials: such as straw, rice husk, sugarcane fiber, wood chips, wood shavings, wood fiber and their products. Large, easy to rot after damp, easy to decompose or burn at high temperature; inorganic heat insulation materials: mineral wool, expanded vermiculite, expanded perlite, diatomite gypsum, glass fiber, rock wool, aerated concrete, foam concrete And its products, etc. These materials do not rot and have good high temperature resistance, but some of them are highly hygroscopic and easy to burn; metal heat insulation materials: mainly aluminum and its products, using the radiation characteristics of the material surface to obtain heat insulation performance , materials with such surface properties hardly absorb the heat incident on it, and their ability to radiate heat is also very small. This type of material has fewer sources, more expensive prices, and a narrower range of applications.

In addition, the above-mentioned insulation materials are not transparent, which limits the application range of insulation materials to a certain extent.
