Embodiment 1

[0029] The present invention can adopt pinene resin, polyvinyl butyral, ethanol to drop in the reactor according to the proportioning of above-mentioned each component, after stirring for 10-15 minutes with the rotating speed of 15-25 rev / min, leave standstill for 1 -2 hours; Stir for another 15-25 minutes and stand for 4 hours; Stir for another 15-25 minutes and stand for 8-10 hours; Stir for another 15-25 minutes and stand for 2 hours to obtain the product.

Embodiment 2

[0031] The present invention can also mix the pinene resin and ethanol at a temperature of (55-70)°C according to the proportioning of the above-mentioned components, and then stir for 10-15 minutes; drop polyvinyl butyral to Stir at a speed of 15-25 rpm, stir for 15 minutes, and then stand for 2 hours; stir for another 15 minutes, and stand for 2 hours to obtain the product.

[0032] The products made in Embodiment 1 and Embodiment 2 all reach the regulation of the national standard G B18581-2001 of the People's Republic of China and the enterprise standard of varnish after testing. Therefore, the present invention is a non-polluting varnish and a method of making the same. There is no pollution in the production process or in the use process, and the product itself has excellent performance.

Abstract

A non-pollution varnish is prepared from pinene resin, polyvinyl butyral and alcohol through proportional mixing, stirring and laying aside. Its advantages are high transparnecy and film forming performance, high resistance to high temp, low temp. water, oil and impact high drying speed and low cost.

Description

Technical field: [0001] The invention relates to a paint and a production method. In particular, a pollution-free varnish and a manufacturing method thereof. Background technique: [0002] At present, paints for interior decoration, including nitro paints, polyester paints, alkyd paints, etc., all contain a large amount of harmful volatiles, such as: benzene, toluene, xylene, free toluene diisocyanate, etc., the volatilization of these harmful volatiles , seriously polluting the environment, threatening and damaging people's health. Invention content: [0003] The invention aims to provide a pollution-free varnish and its preparation method. [0004] The preparation method of the present invention is: [0005] Pinene resin, polyvinyl butyral, ethanol are according to weight ratio: [0006] Pinene resin: polyvinyl butyral: ethanol = (18-20): (16-18): (66-62) is mixed in a ratio, stirred and left to stand to become a product. [0007] The invention adopts resin polymeri...
