Problems solved by technology

[0003] The anti-fogging coating liquid used in the coated polyolefin film mostly uses nano-aluminum sol and acrylic emulsion as the main components of the coating liquid. Due to the drag, friction and outdoor strong winds, the coating layer cannot Avoid external forces that will cause damage to the coating layer, which is manifested as the failure of anti-fog and anti-drip properties during use
[0004] In order to solve the above problems, the method of secondary spraying of anti-fog and waterproof coatings is mainly used, but there are problems of laborious and labor-intensive operations and frequent operations

preparation example Construction

[0031] In the present invention, there is no special limitation on the preparation method of the water-based scratch-resistant, anti-fog and water-drip coating, and the technical scheme for preparing the composition well-known to those skilled in the art can be used. In the present invention, the preparation method of the water-based anti-scratch, anti-fog and water-drop coating preferably comprises the following steps:

[0032] Mix nano-titanium sol, nano-aluminum sol, water-based polyurethane, water-based acrylic emulsion, water-based scratch resistance additive, vinyl acetate-ethylene copolymer emulsion, polyvinyl alcohol, emulsifier, wetting agent, and deionized water to obtain a water-based Scratch-resistant anti-fog and water-drip coating.

[0033] In the present invention, the mixing time is preferably 1 to 3 hours, more preferably 1.5 to 2.5 hours, most preferably 2 to 2.2 hours; the mixing temperature is preferably 40 to 60°C, more preferably 45 to 55 °C, most prefer...

Embodiment 1

[0045] Dissolve 5g of polyvinyl alcohol with 50g of hot water at 90°C. 10g nano aluminum sol (solid content is 10%, particle diameter is 5nm) and 10g nanometer titanium sol (solid content is 20%, particle diameter is 60nm), 3g waterborne polyurethane (solid content is 5%, particle diameter is 0.5nm) , 1g pure acrylic emulsion (solid content is 10%), 0.2g U.S. Dow Corning's DC-5 environmental protection water-based silicone anti-blocking and scratch-resistant auxiliary agent, 2g vinyl acetate-ethylene copolymer emulsion, 1g polyether organic modification Siloxane, 1g Tween 80, 1.5g dodecyltrimethylammonium chloride, prepared 10g polyvinyl alcohol, and 70g deionized water were stirred at 20°C for 1h at a speed of 200rpm to obtain a water-based scratch-resistant anti-scratch Fog waterproof dripping paint.

[0046] Dilute the obtained water-based anti-scratch, anti-fog and waterproof coating with deionized water at a ratio of 1:8, and apply it to the preparation of polyolefin she...

Embodiment 2

[0049] Dissolve 10g of polyvinyl alcohol with 100g of hot water at 80°C. 5g nano aluminum sol (solid content is 20%, particle diameter is 60nm) and 15g nanometer titanium sol (solid content is 10%, particle diameter is 5nm), 6g waterborne polyurethane (solid content is 30%, particle diameter is 0.5nm) , 2g vinegar-acrylic emulsion (solid content is 25%), 0.5g water-based silicone scratch resistance additive, 3g vinyl acetate-ethylene copolymer emulsion, 1.5g polyether organic fluorocarbon compound, 2g Tween 60, 0.5g Dodecyltrimethylammonium chloride, prepared 10g polyvinyl alcohol, and 70g deionized water were stirred at 45°C for 2 hours at a speed of 400rpm to obtain a water-based scratch-resistant, anti-fog, and water-dropping coating.

[0050] Dilute the obtained water-based anti-scratch, anti-fog and waterproof coating with deionized water at 1:7, and apply it to the preparation of polyolefin shed film. The scratch-proof, anti-fog and water-drop paint is precisely transfe...

Abstract

The invention provides a waterborne scratch-resistant anti-fog anti-dropping paint. The paint comprises, by weight, 1 to 15% of a nanometer titanium sol, 1 to 5% of a nanometer aluminum sol, 0.1 to 10% of waterborne polyurethane, 0.1 to 10% of waterborne acrylic acid emulsion, 0.1 to 5% of a waterborne organosilicon scratch-resistant aid, 3 to 15% of vinyl acetate-ethylene copolymer emulsion, 1 to 12% of polyvinyl alcohol, 0.1 to 2% of a wetting agent, 1 to 10% of an emulsifier and 65 to 90% of deionized water, summing to 100%. The waterborne scratch-resistant anti-fog anti-dropping paint provided by the invention has the characteristics of obvious scratch resistance and good anti-fog and anti-dropping, is free of any organic solvent and has the advantages of no toxicity and environment friendliness; and after a greenhouse with a greenhouse film coated with the paint is used for two years, scratches on a coating of the greenhouse film are obviously reduced, and the anti-fog and anti-dropping performance of the greenhouse film is not obviously changed compared with the initial anti-fog and anti-dropping performance of the greenhouse film.

Description

technical field [0001] The invention relates to the technical field of anti-fogging and waterproofing of polyolefin greenhouse films, in particular to a water-based scratch-resistant, anti-fogging and waterproof coating for polyolefin greenhouse films, a preparation method and an application thereof. Background technique [0002] The coated polyolefin anti-fog and waterproof greenhouse film has the outstanding advantages of good transparency, good anti-fog and waterproof effects, and long-lasting effect. It is mainly used for covering winter greenhouses. In many areas, greenhouse planting has become the main means for farmers to increase their income and become rich. Each peasant family has two to three greenhouses for planting management. The functional requirements of farmers for greenhouse film products are not only high strength, anti-fog, and waterproof. , anti-aging performance and other characteristics, it is more hoped that there will be a polyolefin shed film with a...
