Embodiment 1

[0030] Firstly, 5wt% polyvinyl butyral was added to 85% ethanol solution in an environment of 25° C., and mechanically stirred for 2 hours. Then add 2% phenolic resin, 3% glycerin, and 5% mixture of butyl acetate and butanone (the mass ratio of butyl acetate and butanone is 1:1), and continue mechanical stirring for 1 h until a transparent liquid is finally formed. Immerse the metal substrate in the antirust agent liquid at room temperature for 1 minute and dry in the air for 2 hours, or dry at 70°C for 30 minutes to obtain an antirust film with a thickness of about 5-20nm on the surface of the metal substrate.

Embodiment 2

[0032] First, add the mixture of 10% cooked linseed oil and soybean oil (cooked linseed oil: soybean oil = 90:100) to 80% ethanol solution in an environment of 50°C, stir mechanically for 2 hours, then add 3% beeswax, and continue mechanically stirring 1h, finally add 3% polyethylene glycol, 4% mixture of butyl acetate and butanone (the ratio of butyl acetate and butanone is 1:1), and continue mechanical stirring for 1h until a turbid liquid is finally formed. Immerse the ceramic substrate into the anti-rust film agent at room temperature for 1 minute, dry in the air for 2 hours, or dry at 70°C for 30 minutes to obtain an anti-rust film with a thickness of about 50-100nm.

Embodiment 3

[0034] Firstly, a mixture of 15% cooked linseed oil and soybean oil (cooked linseed oil:soybean oil=95:100) was added to 75% ethanol solution in an environment of 50° C., and mechanically stirred for 2 hours. Then add 4% phenolic resin, continue mechanical stirring for 1h, finally add 2% glycerin, 4% mixture of butyl acetate and butanone (the ratio of butyl acetate and butanone is 1:1), continue mechanical stirring for 2h, until a thin paste is finally formed. At room temperature, use a short-haired roller brush to coat the wood substrate once, and a film of 50-100nm can be formed. If recoated, a film of about 80-120nm can be formed. Generally, the number of coatings should not exceed three times, otherwise wrinkled skin may form.

Abstract

The invention relates to a non-water-based transparent tight film pasting agent and a preparation method thereof. The non-water-based transparent tight film pasting agent is prepared from 5wt% to 25wt% of organic film forming agent, 75wt% to 90wt% of organic solvent, 2wt% to 5wt% of thickening agent, 2wt% to 5wt% of plastic modifier and 4wt% to 5wt% of anti-blushing agent, wherein the organic film forming agent is polyvinyl butyral or a mixture of boiled linseed oil and soybean oil. The tight film pasting agent provided by the invention has the characteristics of being quick in film drying speed, good in fit, high in transparency and free from a peculiar smell, and can be used for preventing rust, preventing dust and preventing sunlight damage.

Description

technical field [0001] The invention relates to a non-water-based transparent adhesive film agent, which is suitable for antirust and waterproof protection on the surfaces of wooden products, ceramic products and metal products. Background technique [0002] Among many anti-rust paints and anti-rust oils, low transparency and paint peeling are common, and some anti-rust products also contain harmful metal elements such as lead and chromium, which will pollute the human body and the environment. Therefore, it is very important to solve anti-rust and paint removal and to develop green and harmless anti-rust products. Contents of the invention [0003] In view of the above problems and based on the emphasis on environmental protection, the object of the present invention is to provide a green and harmless transparent anti-rust film agent with long protection time. [0004] On the one hand, the present invention provides a non-water-based transparent adhesive film agent, comp...
