Abstract
The invention relates to a photocuring paint which is prepared from the following raw materials in parts by weight: 10-30 parts of polyester acrylate, 20-40 parts of epoxy acrylate, 20-30 parts of styrene, 1-10 parts of zinc oxide, 1-10 parts of talcum powder, 50-200 parts of deionized water, 1-5 parts of sodium dodecylsulfate, 1-8 parts of ammonium persulfate 3-10 parts of potassium persulfate and 1-5 parts of photoinitiator. The photocuring paint is a water-based paint; by using deionized water instead of the organic diluent, the photocuring paint has lower toxicity and irritation, and is easier for production manufacturing and viscosity control; the obtained cured film has the advantages of high adhesive force for the substrate, high abrasive resistance, low shrinkage and short curing time; and the paint has high stability.
Description
Technical field
The present invention relates to a kind of photo-cured coating and preparation method thereof, belong to chemical material technical field.
Background technology
Photo-cured coating claims again photoactive coating, mainly photosensitive resin, photosensitizers (light trigger) and thinner, consists of, and adds some additives simultaneously, as thermo-stabilizer, adds pigment and filler while preparing colored paint.
Ultraviolet light polymerization refers to that take ultraviolet ray is quickly converted to the process of solid completely as the liquid material of energy initiation reaction.The method that traditional paint solidification is normally physical dryness by heating is removed the solvent in macromolecular solution, obtains the paint film of sclerosis.Ultraviolet light polymerization mechanism is: a network polymer can be interconnected to form by macromolecular chain, again can be by least containing the monomer of 2 active sites on those each molecules or the reaction of oligopolymer forms.When ultraviolet radiation causes causing, be the chain reaction that a kind of speed of response is exceedingly fast immediately.Because most of monomer molecule does not produce spike conventionally under ultraviolet radiation, therefore must add light trigger, typical ultraviolet light polymerization formula must comprise 2 basal components: can effectively absorb UV-light and can efficiently produce the light trigger of spike and at least with 2 monomer or oligopolymer that can form the unsaturated group of polymer network.
With general curing comparison, ultraviolet light polymerization has following advantages: 1. set time short, speed is fast, can in several seconds, solidify, and can be applied to require quick-setting occasion; 2. do not need heating, the material that the thermal capacity such as the material that this should not heat for covering with paint timber, paper, plastics etc. and concrete, thick sheet metal are large is very useful; 3. can be mixed with solvent-free product, reduce topsoil, be conducive to environmental protection; 4. save energy, the efficiency of ultraviolet source will be higher than baking oven; 5. solidification process can automated operation, improves the level of automation in producing, thereby enhances productivity and economic benefit.
Ultraviolet light polymerization oiliness coating is a current most widely used class uv curing coating, but exist some shortcomings, conventional acrylate can cause allergic, and there is irritating smell, and curing mechanism belongs to free radical to be caused, generally to be subject to preventing of oxygen, easily cause surface cure bad etc.; UV curing powder coating is a new technology that traditional powder coating and ultra-violet curing technology are combined, but cost is higher.Ultraviolet solidified aqueous coating combines the features of traditional ultraviolet-curing paint and water-borne coatings, with respect to traditional photocuring oil paint, has the advantages such as raw material sources are wide, cheap, suitability strong, good product quality.
