A kind of solvent-free ultraviolet ray UV photocuring bead paint and its preparation and use method

Abstract

The invention discloses solvent-free type ultraviolet (UV) photocuring water drop paint and a preparation and use method thereof. The solvent-free type ultraviolet (UV) photocuring water drop paint is prepared from, by mass, 5-7 parts of aliphatic polyurethane 6 functional group crylic acid oligomer, 17-19 parts of aliphatic polyurethane 2 functional group crylic acid oligomer, 53.5-56.5 parts of bisphenol A epoxy 2 functional group crylic acid oligomer, 5-7 parts of tripropylene glycol diacrylate (TPGDA) monomers, 7-9 parts of 1,6-high definition discrete architecture (HDDA) monomers, 10-12 parts of pentaerythritol triacrylate (PET3A) monomers, 3-5 parts of 2-hydroxy-2-methyl-1-phenyl-1-acetone light initiator (1173), 2-3 parts of benzophenone photoinitiator (BP), 7-9 parts of reaction type tertiary amine promoter and 0.45-0.55 part of polyether modified polydimethylsiloxane flatting agent. According to the solvent-free type ultraviolet (UV) photocuring water drop paint and the preparation and use method thereof, energy saving and environment friendliness can be achieved, operation is easy and convenient, a water drop shape is naturally formed, curing and drying are fast, the visual effect is good, and the paint is suitable for indoor PVC coated wall slab decoration of building houses.

Description

【Technical field】 [0001] The invention relates to the technical field of chemical coatings, in particular to the technical field of a solvent-free ultraviolet UV photocurable bead paint and its preparation and use methods. 【Background technique】 [0002] Civil coatings are widely used in interior and exterior decoration of buildings and homes. Traditional coatings form a dense and flat protective film on the coating substrate, which cannot naturally form the artistic effect of natural water droplets with strong three-dimensional effect. [0003] In order to meet people's increasing visual requirements for paint decoration, various artistic paints have emerged in the market. When these paints form their own artistic effects, they all require artificial special operations, such as using special tools or specific patterns. Molds, etc., volatilize VOC substances that pollute the air during the drying process, and need to be heated and dried for a long time, which is time-consum...

[0003] In order to meet people's increasing visual requirements for paint decoration, various artistic paints have emerged in the market. When these paints form their own artistic effects, they all require artificial special operations, such as using special tools or specific patterns. Molds, etc., volatilize VOC substances that pollute the air during the drying process, and need to be heated and dried for a long time, which is time-consuming and labor-intensive
