Problems solved by technology

These bio-based organic stains generally cannot be washed directly with water, and tend to further absorb dust and microbial particles in the air and gradually solidify due to incomplete and untimely cleaning. At this time, bio-based organic stains will be more stubbornly combined on the polyurethane surface. The surface of the coating; at the same time, these stains are also prone to breed various microorganisms, which bring direct harm to our life and health
At present, the cleaning of such stains is mainly carried out by various detergents with surfactants as the main components. The stain removal process is from the outside to the inside, so the amount of surfactants is often large, the efficiency of stain removal is low, and time-consuming and labor-intensive And other issues

Abstract

The invention discloses a polyurethane cleaning agent for pretreatment. The polyurethane cleaning agent is a spraying agent and is composed of composite hydrolase (0.01 to 5%) and auxiliary materials; wherein the composite hydrolase is one or more of protease, lipase, amylase and oxidation-reduction enzyme. The cleaning agent is characterized in that composite biological hydrolase active molecules are added, after direct spraying, hydrolase can stably adhere on the surface of polyurethane through biological affinity interaction, physical absorption and chemical bonding; and thus the polyurethane coating can clean biology base organic stains easily. The pretreatment cleaning agent is sprayed on the polyurethane surface; when organic or biological stains are combined to the coating surface, part of organic or biological stains that contact with the coating can be degraded immediately; thus the bonding force between whole stain particles and the coating is weakened, the cleaning efficiency is improved, the using amount of chemical detergent is reduced, the safety is improved, and the water is saved.

Description

technical field [0001] The invention belongs to the field of chemistry and relates to a cleaning agent, in particular to a polyurethane material surface pretreatment cleaning agent. Background technique [0002] The full name of polyurethane is polyurethane, which is a general term for macromolecular compounds containing repeated carbamate groups in the main chain. It is formed by addition polymerization of organic diisocyanate or polyisocyanate and dihydroxy or polyhydroxy compounds. Polyurethane coatings generally have the characteristics of high strength, high wear resistance and solvent resistance, and can be directly and firmly attached to the surface of various organic or metal materials. Therefore, it has been widely used in contact interface coating materials closely related to our daily life, such as furniture coatings, building material coatings, automotive coatings and textiles. [0003] Bio-based organic stains mainly refer to the stain compounds that are often ...
