Technical Field

The invention relates to a heat insulation material, in particular to a formula of a heat insulation material applied to a water tank of a solar water heater.

Background

The heat insulating material which can be used as the water tank at present mainly comprises polyurethane foam, phenolic foam, superfine fiber and the like. The polyurethane foam is prepared by mixing isocyanate and a polyether composition, pouring the mixture into a mold or a cavity of a water tank, and foaming, wherein the polyether composition contains polyether polyol, a foaming agent, a catalyst, a stabilizer and the like. The polyurethane foam material is the best heat-insulating material recognized in the world at present, has the advantages of small heat conductivity coefficient, high compressive strength, good cohesiveness, easy processing and the like, and is widely applied to heat insulation of refrigerators and freezers of electric appliances, building walls, industrial pipelines and transportation and refrigeration vehicles, which is a new growth point of application requirements in recent years. However, compared with the traditional inorganic heat insulation material, the non-flame-retardant polymer foam material including polyurethane foam material has the defects of flammability, high flame propagation speed and the like.

Disclosure of Invention

The invention provides a formula of a heat-insulating material for a water tank of a solar water heater, aiming at overcoming the defects of the prior art.

The technical scheme of the invention is as follows: the formula of the heat-insulating material for the water tank of the solar water heater is prepared from the following raw materials in parts by weight: 60-70 parts of glycerol glucoside polyether polyol, 5-10 parts of chitosan, 8-15 parts of dimethyl methyl phosphate, 8-15 parts of titanium dioxide, 5-10 parts of aluminum silicate and 2-10 parts of calcium chloride.

The raw materials adopted by the invention are nontoxic and harmless, and have no adverse effect on human bodies and environment. The glycerol glucoside polyether polyol is synthesized by processing starch, and has the advantages of wide raw material source, low cost and safe and reliable processing process. According to the invention, the low molecular weight chitosan is added, so that the foamed polyether material has mutually communicated pores, small pores are formed among the walls of the large pores, the chitosan is adsorbed on the inner surface of the pores, the generated pores are not easy to break, the pore size can be increased, the expansion rate of the polyether material is improved, and the heat preservation effect is obviously improved.

Compared with the prior art, the invention has the following advantages:

1. the invention is used on the surface of the water tank of the solar water heater, has high heat absorption rate and improves the heating efficiency.

2. The material of the invention overcomes the defect of large shrinkage after foaming molding, avoids the deformation of the water tank and ensures the heat preservation performance of the water tank of the water heater.

3. Durable, long service life, can improve more than 25% of service life.

4. The product is green and environment-friendly and has no pollution.
