Problems solved by technology

However, with the continuous improvement of people's living standards, the quality requirements for daily necessities are also getting higher and higher. The performance of traditional PVA collodion is not ideal, and the shortcomings are gradually highlighted: ①The production process needs to consume a lot of water (about 30 tons of products are consumed to produce 1 ton of products) water), high resource consumption; ② Starch is needed in the production process, and the use of starch will generate high chemical oxygen demand, causing water pollution; ③ The material is easy to dry and hard, which is not conducive to family life; ④ PVA is a thermosetting material , is not easy to degrade, and is a restricted material in the United States and the European Union

Abstract

The invention relates to a polyurethane material for mops, which is prepared from a polyurethane composition, and the polyurethane composition comprises the following components by mass: 7.5-15 partsof a polyol component, 15-30 parts of an isocyanate component, 0.2-3 part of a chain extender, 0.1-3 part of an organometallic compound catalyst, 0.2-10 part of an amine catalyst, 0.2-5 part of a foamstabilizer, and 1-5 parts of a foaming agent. By using the product, the water absorption capacity of collodion is greatly improved, the service life of the collodion is greatly prolonged, starch andwater are not consumed in the production process, the problems of high energy consumption and high pollution in the production process are solved, and meanwhile the industry difficulty problem that products are prone to hardening in the mop industry is solved.

Description

technical field [0001] The invention belongs to the technical field of cleaning supplies, and in particular relates to a polyurethane material for a mop. Background technique [0002] Household cleaning products widely use polymer foam as the base material, especially since the successful development of polyvinyl alcohol (PVA) formal foam by the British Wiltex Company in 1945, the foaming and production processes of PVA collodion have become more and more diverse. It is becoming more and more widely used in household cleaning products. However, with the continuous improvement of people's living standards, the quality requirements for daily necessities are also getting higher and higher. The performance of traditional PVA collodion is not ideal, and the shortcomings are gradually highlighted: ①The production process needs to consume a lot of water (about 30 tons of products are consumed to produce 1 ton of products) water), high resource consumption; ② Starch is needed in th...
