Formula of polyurethane foaming product with good air filtering effect

Abstract

The invention discloses a formula of a polyurethane foaming product with a good air filtering effect. The formula comprises isocyanate, polyether, glycerol, a catalyst, a flame retardant, a modified reinforced fiber net, an auxiliary additive, isopropanol, a binder, palygorskite and sepiolite. Bamboo fibers, carbon fibers and a filter screen pipe are interwoven to form a mixed weaving fiber net structure. A plant leaf and stem extracting solution in the soaking solution enters pores of the mixed woven fibers; air entering the mixed weaving fiber net structure is purified and deodorized; a composite salt solution is used as a cosolvent, so that the plant leaf and stem extracting solution can be accelerated to enter pores of the mixed woven fibers, the modification speed is increased, alkaline metal ions contained in the composite salt solution can play a role in sterilization and disinfection, and the filtering effect is optimized; palygorskite and sepiolite are added into a finished polyurethane foaming product, impurities in air are adsorbed by means of the unique layer chain structure characteristic and the nano scale hole channel microstructure of palygorskite and sepiolite, andthe filtering effect is better.

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a polyurethane foam product formula with good air filtering effect. Background technique [0002] Polyurethane foam products are products made of polyurethane rigid foam. Polyurethane rigid foam is mainly made of isocyanate and polyether. It is a high-molecular polymer that is mixed with equipment and foamed on-site by high-pressure spraying. Due to its low thermal conductivity, it is often used as thermal insulation and waterproof materials in the construction field. [0003] During the use of polyurethane foam products, there are pores between the rigid foams, and air can pass through the pores of the rigid foams. However, due to the generally poor air quality in the building environment, the poor quality air flows directly from the pores. Through the middle, the air inside the polyurethane foam product is polluted, and the existing polyurethane foam product does not have the...
