Production and manufacturing formula of flame-retardant layer on surface of polyurethane foaming product

Abstract

The invention discloses a production and manufacturing formula of a flame-retardant layer on the surface of a polyurethane foaming product. The formula comprises the following components in parts by weight; 10 to 12 parts of pentaerythritol; 3 to 5 parts of ammonium dihydrogen phosphate; 1 to 3 parts of dicyandiamide; 3-9 parts of aluminum hydroxide, 2-5 parts of silicon dioxide, 1-2 parts of calcium carbonate, 3 to 5 parts of hydrated zinc borate; 1 to 1.5 parts of boehmite; 2 to 5 parts of polydimethylsiloxane; 1 to 2 parts of molybdenum trioxide; 4-6 parts of decabromodiphenyl ether, 4-7 parts of magnesium hydroxide, 30-50 parts of acrylic resin, 12-18 parts of dibutyl phthalate, 2-4 parts of sodium dodecyl benzene sulfonate, 10-18 parts of butyl acetate, 1-4 parts of nano montmorillonite, 3-6 parts of a silane coupling agent, 9-13 parts of titanium dioxide, 1-2 parts of expanded graphite and 0.5-1.2 parts of silicone oil. The polyurethane foaming product is effectively protected, and the problem that the flame retardant property of the polyurethane foaming product is reduced after the polyurethane foaming product is used for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of polyurethane foam, in particular to a formula for producing a flame-retardant layer on the surface of a polyurethane foam product. Background technique [0002] Polyurethane foam has a wide range of applications and has penetrated into almost all sectors of the national economy, especially in furniture, bedding, transportation, refrigeration, construction, heat insulation and other sectors, and has become one of the indispensable materials. It has become one of the most widely used varieties in plastics. Polyurethane soft foam is mainly used in furniture, bedding and other household items, such as sofas and seats, back cushions, mattresses and pillows; polyurethane rigid foam is mainly used in heat insulation, refrigeration equipment and cold storage, heat insulation panels, wall insulation , pipeline insulation, storage tank insulation, single-component foam caulking materials, etc. Although the current...

Problems solved by technology

Polyurethane soft foam is mainly used in furniture, bedding and other household items, such as sofas and seats, back cushions, mattresses and pillows; polyurethane rigid foam is mainly used in heat insulation, refrigeration equipment and cold storage, heat insulation panels, wall insulation , pipeline insulation, storage tank insulation, single-component foam caulking materials, etc. Although the current polyurethane foam will add corresponding flame retardants in the process of polyurethane foaming in order to improve the flame retardancy, so that polyurethane foam products have Corresponding flame retardant function, but after long-term use, the flame retardant effect will be reduced. Therefore, a production formula for the surface flame retardant layer of polyurethane foam products is proposed.
