Abstract
The invention discloses a preparation method and a production device of an anti-pilling and anti-oil-staining modified polyurethane coating. The polyurethane coating comprises a base layer, a polyurethane cloth and an oil-proof layer. The production device comprises two vertical plates, and the upper end of a support arm is installed There is an agitator, an oven is installed on the bottom of the agitator, an upper roller and a paint roller are arranged between the vertical plates, a paint tank is arranged under the paint roller, a cylinder is fixedly installed on one side of the connecting base, and a cylinder is fixedly installed on one end of the cylinder. Scraping head; the polyurethane coating has good anti-sticking oil performance, and the titanium dioxide in the oil-proof layer can also decompose the oil stain on the surface of the polyurethane coating under light to ensure that the surface of the polyurethane coating is clean; the distance between the scraping head and the polyurethane cloth is controlled by the cylinder , the thickness of the oil-proof layer can be precisely controlled, and the polyurethane cloth is extruded by two shaping rollers to eliminate the burrs on the surface of the oil-proof layer. The production device can automatically paint and generate the oil-proof layer, reducing labor intensity.
Description
technical field [0001] The invention relates to the technical field of polyurethane coatings, in particular to a method for preparing an anti-fluffing and anti-oil staining modified polyurethane coating and a production device thereof. Background technique [0002] With the progress of the times, people's aesthetic concepts are becoming more and more diversified. At the same time, higher requirements are put forward for the anti-pilling and oil-proof performance of polyurethane coatings. The existing polyurethane coatings are easily polluted by oil stains; [0003] The patent document (CN207003687U) is a polyurethane waterproof coating, which belongs to the technical field of waterproof coating. It includes an attapulgite paste-like water-resistant putty layer, permanent liquid DPS waterproof coating, polyester non-woven fabric, high-strength polyurethane waterproof coating and anti-crack protective coating. The attapulgite paste-like water-resistant putty layer is applied o...
