Abstract

The invention discloses a composite sponge and a preparation process thereof. The composite sponge comprises a polyurethane sponge and a polyvinyl alcohol sponge compounded in the network gap of the polyurethane sponge, and the density of the composite sponge is 45-150kg / m 3 (dry product), the hardness of the composite sponge is greater than 30HD, the volume of the polyvinyl alcohol sponge accounts for 60-80% of the total volume of the composite sponge, and the volume of the polyurethane sponge accounts for 20-40% of the total volume of the composite sponge , the pore diameter of the polyurethane sponge is 3-30PPI, and the volume weight of the polyurethane sponge is 15-50kg / m 3 . The composite sponge of the invention has strong ability to scrape dirt, does not cause damage to the surface of the object to be wiped, has high water absorption and water retention characteristics, and has good cleaning effect.

Description

technical field [0001] The invention belongs to the technical field of cleaning products, in particular to a sponge for wiping. Background technique [0002] At present, there are many cleaning tools on the market for cleaning floors, kitchen utensils, and furniture, such as plant fiber cloth, metal wire balls, and sponges. Metal wire balls are easy to prick people and damage the objects to be wiped. For cleaning wooden floors and furniture, the plant fiber cloth is soft, but the cleaning effect is poor, and dirt is easy to remain on the surface of the wipe. Sponge is usually made of polyurethane, which is a porous body with a network structure, a coarse-celled polyurethane elastomer disclosed in Chinese Patent Publication No. CN102027030B, with a density of 70 to 300 g / L and 1 to 20 pores / cm The wiping body with such a porous structure has a strong ability to remove dirt and will not cause damage to the wiped object. [0003] However, the pores of the polyurethane sponge ...
