Problems solved by technology

[0002] Nowadays, automobiles and home appliances, especially automobiles, often have the following problems during storage and transportation: in the open parking lot, due to the erosion of rain, especially acid rain, humidity and sunlight, the paint coating will be damaged. Phenomena such as light, discoloration, cracks, peeling, peeling and aging
So far there is no other better way to effectively protect the surface of automobiles and home appliances

Abstract

The invention relates to a water protective paint for automobile and domestic surfaces, and its weight proportions: a water resin latex composed of acrylic resin 70-85 shares, modified acrylic resin 10-25 shares and epoxy resin 5-10 shares, reinforcing agent 1-3.5 shares, thixotropic agent 1-3 shares and film-forming agent 1-4 shares; where the reinforcing agent is silicon dioxide with particle size below 15 mum, the thixotropic agent is fibrin compound with molecular weight 1500-6000, and the film forming agent is one or two of the glycol and propylene alcohol. It has proper strength, hardness, flexibility and elongation. It has no bad effect on original paint coated surfaces of automobiles, home appliances, etc and can play a good role in protecting.

Description

Technical field: [0001] The invention relates to the field of paint industry, in particular to a water-based protective paint for the surface of automobiles and home appliances. Background technique: [0002] Nowadays, automobiles and home appliances, especially automobiles, often have the following problems during storage and transportation: in the open parking lot, due to the erosion of rain, especially acid rain, humidity and sunlight, the paint coating will be damaged. Light, discoloration, cracks, peeling, peeling and aging. Dust, dust, oil stains, fingerprints and other dirt during storage and transportation will seriously pollute the surface coating of the car, and even be stained with variegated colors, which will make the whole car look old and affect the appearance and sales. Scratches and abrasions during storage and transportation will reduce the surface quality, and serious cases will cause repairs and increase costs. For this reason, in order to prevent the o...
