Problems solved by technology

[0002] At present, traditional antifouling paints are composed of relatively inert paint bases containing biocide pigments that can be leached from the paint. The paint base used is vinyl resin and rosin. Such paints have poor adhesion and poor antifouling effect. Does not protect the PVC substrate very well

Abstract

The invention discloses an ultraviolet light-cured PVC (polyvinyl chloride) anti-dirt paint. The anti-dirt paint comprises the following raw materials in percentage by weight: 20%-25% of aliphatic polyurethane diacrylate, 20%-23% of aliphatic polyurethane tetraacrylate, 8%-10% of TMPTA (trimethylolpropane triacrylate), 8%-15% of HEMA (hydroxyethyl methacrylate), 10%-15% of tetrafluoropropyl acrylate, 10%-15% of TPGDA (tripropylene glycol diacrylate) and 0.3%-0.5% of leveling agent. The paint disclosed by the invention has the advantages of good surface adhesion and relatively good anti-dirt effect against PVC substrates.

Description

technical field [0001] The invention relates to an ultraviolet photocuring PVC antifouling paint. Background technique [0002] At present, traditional antifouling paints are composed of relatively inert paint bases containing biocide pigments that can be leached from the paint. The paint base used is vinyl resin and rosin. Such paints have poor adhesion and poor antifouling effect. Can not protect the PVC substrate very well. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultraviolet photocurable PVC anti-fouling paint with good adhesion and good anti-fouling effect. [0004] In order to solve the above problems, the present invention is achieved through the following technical solutions: a kind of ultraviolet light curing PVC anti-fouling paint of the present invention, this anti-fouling paint is composed of the percentage of the following raw materials: aliphatic polyurethane diacrylate 20% -25%,...
