Abstract

The invention discloses a novel solar environmentally-friendly thermal insulation material. The material is prepared from polyurethane, polyether, polybutylene glycol, vinyl resin, white latex, fly ash, talc, calcium carbonate powder, montmorillonoid powder, silicone oil, silicon carbide fiber, glass fiber, polypropylene fiber, hydroxypropyl methyl cellulose, maleic anhydride-grafted compatilizer, an acrylic acid bridging agent, a dispersing agent NC, stannous octoate, azodicarbonamide, an acrylic ester foaming control agent, silicone amide, an epoxy resin binder, dioctyl adipate, liquid polybutadiene rubber, polyaluminum cloride, p-hydroxybenzenesulfonic acid, styrene, a fatty acid stabilizer, an antioxidant 1010, decabromodiphenyl ethane, ammonium octamolybdate and 2-hydroxyl-4-methoxybenzophenone. The prepared novel solar environmentally-friendly thermal insulation material has no deformation phenomenon at high temperature and low temperature; in addition, the compressive strength is high, the flame retardant efficiency is good, an atmospheric ozone layer is not destroyed, and the novel solar environmentally-friendly thermal insulation material is excellent in property.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and the technical field of preparation of thermal insulation materials for solar water heater water tanks, and in particular relates to a novel solar energy environmental protection thermal insulation material. Background technique [0002] Polyurethane thermal insulation material is a very important synthetic material, with excellent physical and mechanical properties and chemical resistance, especially low thermal conductivity, is a high-quality thermal insulation material, widely used in refrigerators, freezers, automobile industry, construction industry . In polyurethane rigid foam, the commonly used blowing agent is chlorofluorocarbon (CFC) blowing agent, but because chlorofluorocarbon (CFC) blowing agent has a destructive effect on the atmospheric ozone layer, in order to maintain the ecological environment, international conventions have adopted it Production and use are s...
