preparation example

[0063] The preparation steps of phosphorus-containing pentaerythritol acrylate monomer:

[0064] According to the molar ratio of cyclic phosphoric anhydride and pentaerythritol acrylate is 1:1.2, weigh cyclic phosphoric anhydride and pentaerythritol acrylate, and then weigh a certain amount of strong acid cation exchange resin catalyst and hydroquinone polymerization inhibitor, wherein the catalyst It accounts for 1% of the total mass fraction of cyclic phosphoric anhydride and pentaerythritol acrylate, and the polymerization inhibitor accounts for 0.2% of the total mass fraction of cyclic phosphoric anhydride and pentaerythritol acrylate.

[0065] Put the weighed cyclic phosphoric anhydride into a three-necked round-bottomed flask equipped with a condenser tube, add a strong acid cation exchange resin and hydroquinone, stir and heat it to 90 ° C through an oil bath, and then slowly use a constant pressure dropping funnel. Pentaerythritol acrylate was added dropwise, and the t...

Abstract

The invention relates to the field of UV coatings, and particularly discloses a transparent flame-retardant UV coating as well as a preparation method and application thereof. The transparent flame-retardant UV coating comprises the following raw materials in parts by weight: 1-10 parts of a hydrogenated polybutadiene acrylate prepolymer; 10 to 30 parts of a polyurethane acrylate prepolymer; 10 to 30 parts of a hydroxyethyl acrylate monomer; 1 to 10 parts of an isobornyl acrylate monomer; 1 to 10 parts of an acryloyl morpholine monomer; 10 to 30 parts of a phosphorus-containing pentaerythritol acrylate monomer; 5 to 10 parts of polyether polyol; 1-5 parts of a photoinitiator; and 0.1-2 parts of an auxiliary agent. The preparation method of the transparent flame-retardant UV coating comprises the following steps: mixing the prepolymer, the monomer, the polyether polyol, the photoinitiator and the auxiliary agent together, and stirring for 20-40 minutes to obtain the transparent flame-retardant UV coating. The transparent flame-retardant UV coating has flame retardance and high transparency at the same time, and can be applied to wood cultural relic coatings with high requirements for flame retardance and transparency.

Description

technical field [0001] The present application relates to the field of UV coatings, and more particularly, to a transparent flame-retardant UV coating and a preparation method thereof. Background technique [0002] With the development of social economy, environmental and cultural relics protection issues have attracted more and more attention. Due to environmental and human factors, historical relics and cultural heritage have suffered more and more serious damage, and the rescue protection of some important civilization products has received more and more attention from research experts in the field of material protection. Therefore, the development of environmentally friendly, low-consumption Energy and multi-functional cultural relics protection materials are particularly important. Traditional chemical protection mostly uses methacrylic compounds, epoxy resins, polyamides, polyurethanes and other materials. When they are applied to wooden cultural relics and buildings,...
