Abstract
The invention relates to the field of coatings, in particular to a photocuring waterproof antibacterial coating. The photocuring waterproof antibacterial coating is prepared from the following raw materials in parts by weight: 55-65 parts of polyurethane formate resin, 3-8 parts of isobutyl triethoxy silane, 2-5 parts of carboxymethyl cellulose, 3-5 parts of nano silver, 5-10 parts of nano titanium dioxide, 5-13 parts of a photoinitiator, 7-12 parts of a reactive diluent, 3-5 parts of a thickening agent, 0.3-0.6 part of a flatting agent, 0.2-0.5 part of an anti-settling agent and 1-2.5 parts of a defoaming agent. The polyurethane formate resin serving as a main material contains free cyano-oxygen ions, so that the coating has water resistant property; the added isobutyl triethoxy silane is capable of penetrating a cementing surface, and permeating into concretes to be subjected to chemical reaction together with air in an acidic or alkaline environment and water molecules in a substrate so as to form a permanent and firm waterproof layer with high environmental friendliness, and the coating permeates deeply and is capable of restraining moisture absorption; the nano silver and the nano titanium dioxide are added, so that the antibacterial property and bacterial inhibition property of the coating are effectively improved.
Description
Technical field
The present invention relates to paint field, especially a kind of photocuring water-proof antibiotic coating.
Background technology
Photocureable coating, owing to having the advantages such as hardening time is short, solidification temperature is low, volatile matter is low, almost occupies whole Coating Market, is widely used in every field.
But under wet environment or water environment, easily absorb moisture and expand, cause the destruction of paint coatings.And under moist or water environment, easy breed bacteria.
Summary of the invention
The present invention is directed to the problems referred to above and propose a kind of photocuring water-proof antibiotic coating, it is possible to use the most for a long time, and effectively prevent bacteria breed.
To achieve these goals, the technical solution adopted in the present invention is, a kind of photocuring water-proof antibiotic coating, its raw material is calculated as by weight: polyurethane formate resin 55～65 parts, isobutyl triethoxy silane 3～8 parts, carboxymethyl cellulose 2～5 parts, nanometer silver 3～5 parts, nano titanium oxide 5～10 parts, light trigger 5～13 parts, reactive diluent 7～12 parts, thickening agent 3～5 parts, levelling agent 0.3～0.6 part, anti-settling agent 0.2～0.5 part, defoamer 1～2.5 parts.
As preferably, a kind of photocuring water-proof antibiotic coating, its raw material is calculated as by weight: polyurethane formate resin 60 parts, isobutyl triethoxy silane 5 parts, carboxymethyl cellulose 3 parts, nanometer silver 4 parts, nano titanium oxide 8 parts, light trigger 10 parts, reactive diluent 10 parts, thickening agent 4 parts, levelling agent 0.5 part, anti-settling agent 0.3 part, defoamer 1.5 parts.
Described light trigger is 1-hydroxy-cyciohexyl phenyl ketone, 2-hydroxy-2-methyl-1-phenyl-1-acetone, one or more compositionss in TMDPO.
Photocuring water-proof antibiotic coating selection polyurethane formate resin of the present invention is major ingredient, dissociate containing a certain amount of-NCO-, coating is made to have excellent resistance to water, coating adds isobutyl triethoxy silane, its small molecule structure having can penetrate cementing properties surface, hydrone generation chemical reaction in the air penetrating into inside concrete and be exposed in acidity or alkaline environment and substrate, form permanent firm high-environmental waterproof layer, percdation, suppression moisture absorption, produces Cl waterproof, anti--, anti-ultraviolet performance and there is breathability；Add carboxymethyl cellulose as adhesive；Addition nanometer silver and nano titanium oxide effectively promote antibacterial, the bacteriostasis property of coating, and nano titanium oxide also has photocatalysis, is that coating has certain self-cleaning property.
Detailed description of the invention
By predetermined purpose and technological means and effect that the present invention reached is expanded on further, below in conjunction with embodiment, specific embodiments of the present invention are described in detail.
