A kind of water-absorbing flame-retardant sponge and preparation method thereof

Abstract

The invention discloses a water-absorption flame-retardant sponge and a production method, which is characterized in that the sponge comprises the following raw materials by weight: 95-110 parts of propylene glycol block polyether, 48-55 parts of toluene diisocynate, 8-10 parts of polyacrylamide, 5-6 parts of antimonous oxide, 0.5-0.75 parts of triethylamine, 3-4 parts of dichloroethane, 3.5-5.5 parts of zinc oxide, 4.0-5.0 parts of glycerol, 0.5-0.7 parts of antioxidant 168, 0.3-0.8 parts of dibutyl tin diacetate, 0.3-0.5 parts of sodium laurylsulfate, 4-5 parts of modifier and 6.5-9.5 parts of water. The sponge has excellent flame retardant performance, water absorption performance, mould resistance and air purification, nano calcium carbonate in the raw materials has a three-dimensional structure, and has good dispersibility, can enhance the hardness of the sponge, and antimonous oxide has good flame retardant effect.

Description

technical field [0001] The invention relates to a preparation method of a sponge, in particular to a water-absorbing flame-retardant sponge and a preparation method thereof. Background technique [0002] Sponge products have been gradually popularized in people's lives, including seats, sofas, mattresses and other household items made of sponges. Polyether polyols are the main raw materials for the production of polyurethane sponges. Polyether polyols are generally used in the production of polyurethane sponges. Alcohols usually use petroleum-based polyether polyols. However, polyurethane made of petroleum-based polyether polyols has high stability and is difficult to decompose in a natural state; making them non-degradable is not conducive to environmental protection and sustainable development. With the expansion of the application field of sponge products, the market needs a large amount of sponge supply. Due to the many performance defects of the current sponges, there a...

[0002] Sponge products have been gradually popularized in people's lives, including seats, sofas, mattresses and other household items made of sponges. Polyether polyols are the main raw materials for the production of polyurethane sponges. Polyether polyols are generally used in the production of polyurethane sponges. Alcohols usually use petroleum-based polyether polyols. However, polyurethane made of petroleum-based polyether polyols has high stability and is difficult to decompose in a natural state; making them non-degradable is not conducive to environmental protection and sustainable development. With the expansion of the application field of sponge products, the market needs a large supply of sponges. Because the current sponges have many performance defects, there are potential safety hazards in the use of sponges.
