example 1

[0014] The invention is an insulating and heat-insulating spray polyurethane foam. The formula is mainly divided into two kinds of materials, A and B. When used, the ratio is 1:1. Among them, the material A is isocyanate, and the formula of B material is: polyester polystyrene Ether 20%, A phenol polymer 20%, polyether polyol 20%, hexafluoropropane 10%, B polymer 10%, triphosphonate 10%, triethyl phosphate 5%, dihydroxydiethyl ether 2%, triethanolamine 1%, dimethylcyclohexylamine 1%, dibutyltin dilaurate <1%, isopropenylbenzene <1%.

example 2

[0016] The invention is an insulating and heat-insulating spray polyurethane foam. The formula is mainly divided into two kinds of materials, A and B. When used, the ratio is 1:1. Among them, the material A is isocyanate, and the formula of B material is: polyester polystyrene Ether 20%, phenol polymer of A 18%, polyether polyol 21%, hexafluoropropane 13%, polymer of B 12%, triphosphonate 8%, triethyl phosphate 4%, dihydroxydiethyl ether 1%, triethanolamine 1%, dimethylcyclohexylamine 1%, dibutyltin dilaurate <1%, isopropenylbenzene <1%.

example 3

[0018] The invention is an insulating and heat-insulating spray polyurethane foam. The formula is mainly divided into two kinds of materials, A and B. When used, the ratio is 1:1. Among them, the material A is isocyanate, and the formula of B material is: polyester polystyrene Ether 17%, phenol polymer of A 18%, polyether polyol 18%, hexafluoropropane 13%, polymer of B 13%, triphosphonate 9%, triethyl phosphate 4%, dihydroxydiethyl ether 3%, triethanolamine 3%, dimethylcyclohexylamine 1%, dibutyltin dilaurate <1%, isopropenylbenzene <1%.

[0019] In the above example, the phenol polymer of A is a phenol polymer obtained by the reaction of formaldehyde, propylene oxide and ethylene oxide; the polymer of B is produced by the reaction of ethylenediamine and methyloxyflurane polymer.

[0020] The above examples are sprayed using the following spraying process, the steps are as follows:

[0021] 1) Preparation: Keep the ambient temperature above 10°C, keep the humidity below 70%,...

Abstract

The invention discloses an insulating and heat-insulating spray-coated polyurethane foam, wherein the components of the formula are mainly divided into two materials A and B, the material A and the material B are matched according to a ratio of 1:1 during the use, the material A is made of isocyanate, and the material B comprises 15-25% of polyester polyether, 10-20% of the phenol polymer of the material A, 15-25% of polyether polyol, 5-15% of hexafluoropropane, 5-15% of the polymer of the material b, 5-15% of triphosphonate, 3-7% of triethyl phosphate, 1-5% of diethylene glycol, 1-5% of triethanolamine, 1-3% of dimethylcyclohexylamine, less than 1% of dibutyltin dilaurate, and less than 1% of isopropenyl benzene. According to the present invention, the insulating and heat-insulating spray-coated polyurethane foam is provided, and has advantages of improved heat resistance, improved heat insulation effect, strong viscosity, high heat resistance, fire retardation, low water absorption and low deformation rate.

Description

technical field [0001] The invention belongs to the field of heat insulation, and in particular relates to a sprayed polyurethane foam for heat insulation and heat insulation. Background technique [0002] Existing thermal insulation materials are all assembled in modules for thermal insulation. For pressure vessels and equipment with different shapes, it is necessary to customize thermal insulation materials of different shapes, which is inconvenient to use and cumbersome to maintain. [0003] The full name of polyurethane foam (PUR) is a one-component polyurethane foam caulking agent, commonly known as foaming agent and foaming glue. It is the product of the cross combination of aerosol technology and polyurethane foam technology. It is a polyurethane prepolymer A special polyurethane product filled with foaming agent, catalyst and other components in a pressure-resistant aerosol can. When the material is sprayed out of the aerosol can, the foamy polyurethane material will...
