A kind of glass cleaner composition adding cationic polymer

Abstract

The invention relates to a glass cleaner composition added with cationic polymers. The glass cleaner composition comprises the following materials: (a) cationic polymers which account for 0.01-3.0 percent of the total weight of the composition, have the general formula shown in the description and have the number-average molecular weight of 40,000-1,000,000, wherein R1 and R3 are one or more of ingredients shown in the description, and R2 is one or more of diallyl-dialkyl-ammonium chloride and N-(quaternary ammonium alkyl)acrylamide; (b) short-carbon-chain fatty alcohol which accounts for 4-40 percent of the total weight of the composition and has 1-4 carbon atoms; (c) a surfactant system which accounts for 0.1-5 percent of the total weight of the composition and at least comprises an ampholytic surfactant or an anionic surfactant; (d) at least one alkali of which the amount is enough to enable the pH value of the composition to range from 5 to 11; (e) one or more washing assistants; (f) the balance of water. The glass cleaner composition added with the cationic polymers can effectively improve the surface hydrophilicity of glass and has relatively good washability.

Description

technical field [0001] The invention relates to a glass cleaner composition, in particular to a liquid detergent composition for cleaning the surfaces of glass doors and windows, automobile glass and other glass products. Background technique [0002] Because of its smooth, transparent, crystal clear, good light transmittance and cost performance, glass is a widely used building material and decorative material. However, glass is easily contaminated by dust, oil stains and other dirt during use, and after the glass is contaminated, it will seriously affect the line of sight and the appearance of finishing. At present, the glass cleaners on the market are usually composed of surfactants, alcohol ether organic additives, chelating agents and other components, which are easily washed away by rainwater and sewage, so they only have a single decontamination ability and do not have a long-term effect. The ability to maintain the cleaning effect and the wash-resistant effect, so t...

Problems solved by technology

However, the hydrophilic modification effect of the cationic polysaccharide polymer on the glass surface is not ideal, and the washing resistance effect is limited

Chinese patent CN 101821371 discloses a hard surface cleaning composition adding nonionic surfactants, acids and hydrophilic polymers. Although the composition has achieved a good hydrophilic modification effect on the surface of ceramic tiles, the described Hard surface cleaning compositions are free of anionic and amphoteric surfactants

In addition, the pH value of the composition is below 3. Although this has good detergency for soap scum and scale, it will weaken the removal power for grease dirt under low pH value conditions, which may affect the transparency of the glass. At the same time, it may irritate the eyes and skin of consumers and affect the safety of consumers during use.

[0006] In summary, it can be seen that hydrophilic polymers do help to improve the washing effect of glass cleaning products and give the glass surface a good hydrophilic effect, but the maintenance time and washing resistance of this hydrophilic effect still cannot meet the current requirements. consumer needs
