Abstract
The invention provides quick-drying water-based paint which comprises the following components in parts by mass: 60-85 parts of a resin emulsion, 10-20 parts of deionized water, 5-12 parts of a coalescing agent, 0.1-0.3 part of a surfactant, 0.2-0.6 part of a defoaming agent, 0.5-1 part of a flatting agent, 0.3-0.8 part of a substrate lubricant, 0.1-0.3 part of a preservative, 0.3-0.5 part of ammonia water and 0.1-0.2 part of a thickener. The quick-drying water-based paint provided by the invention has the characteristic of being environmental-friendly. In addition, with assistance of auxiliaries such as the coalescing agent and the like, the prepared paint is excellent in adhesive force, quick in drying speed, high in hardness, good in wear resistance, water-resistant, high in glossiness, low in VOC content and low in toxicity and pollution, and meets the general trend of energy conservation and environmental protection.
Description
Technical field
The invention belongs to paint field, particularly a kind of can the water-borne coatings of quick-dry type.
Background technology
China is the big country that toy is produced and exported, but a lot of individual workship toy of working it out often index is undesirable, especially European Union area is sold to, this area formulates the regulation relevant to the toxicity related request such as harmful heavy metal, phthalic ester plasticizer and VOC for plastic toy goods, toy domestic in usually causing is detained because of not up to standard etc. to be dropped sharply, not only have impact on market, and compromise made in China reputation.Therefore, the water-borne plastic coatings of development low toxicity, low stain, low VOC content, imperative in plastic toy industry.
Summary of the invention
The technical problem solved: for the deficiencies in the prior art, the invention provides a kind of quick-dry type water-borne coatings, solves the defective technical problem of environmental protection index that existing plastic toy coating exists.
Technical scheme: for solving the problems of the technologies described above,
A kind of quick-dry type water-borne coatings, comprises the component that massfraction is following: resin emulsion 60 ~ 85 parts, deionized water 10 ~ 20 parts, film coalescence aid 5 ~ 12 parts, 0.1 ~ 0.3 part, tensio-active agent, defoamer 0.2 ~ 0.6 part, flow agent 0.5 ~ 1 part, ground wetting agent 0.3 ~ 0.8 part, sanitas 0.1 ~ 0.3 part, ammoniacal liquor 0.3 ~ 0.5 part, thickening material 0.1 ~ 0.2 part.
The present invention take resin emulsion as matrix, in addition not within the scope of VOC and the film coalescence aid that toxicity is lower, is aided with other auxiliary agents simultaneously, such that final product sticking power is good, water tolerance good and the feature that film coated surface defect is few.
Concrete, resin emulsion belongs to the category of environment-friendly type aqueous coating, is suitable for the product of toys.Secondly, desirable film coalescence aid, effectively should reduce the second-order transition temperature of low-grade polymer, be convenient to film formation at low temp; In water, solubleness is little, easily with adsorbed by latex particle and make it plastify distortion; There is good consistency, do not affect outward appearance and the glossiness of film; Speed matters can be sent out, while taking into account film forming, be convenient to rapid drying.General selection alcohol ethers and alkoxide solvent are as film coalescence aid.
As preferably, in the present invention, stating resin emulsion is acrylate copolymer emulsion.This this emulsion by vinylbenzene, vinyl cyanide and vinylformic acid three class monomer copolymerization form, the hardness of this emulsion film, tensile strength and wear resistance increase, and water tolerance and solvent resistant ability are also strengthened, and also ensure that film can obtain specular removal fruit.In addition, the molecular-weight average of emulsion is 20000, and surface acrylic emulsion also has snappiness to a certain degree, and second-order transition temperature is not too high is about 50 DEG C, can not only take into account the mechanical property of film, can also reduce the usage quantity of film coalescence aid.
As preferably, in the present invention, described film coalescence aid is propylene glycol.Secondly film coalescence aid should be noted 2 points when adding, and first avoids the film coalescence aid of high density to add in emulsion produces breakdown of emulsion, and appropriate stage in process of production adds, and controls interpolation speed.
As preferably, in the present invention, described defoamer is the one in BYK-024, BYK-28 and Foamex80.The main component of these three kinds of defoamers is all polyether-modified polysiloxane, and containing hydrophobic nature particle, effect is ideal, and film also can not produce surface imperfection.
Beneficial effect: the present invention take resin emulsion as substrate, there is eco-friendly feature, be aided with the auxiliary agents such as film coalescence aid in addition, the city made coating has sticking power excellence, rate of drying is fast, hardness is high, wear resistance is good, water-fast, glossiness is high, VOC content is low, low toxicity low stain, meet the megatrend of energy-conserving and environment-protective, meanwhile, the cost value of coating of the present invention and solvent based coating are more or less the same.Be applicable to plastic toy, family's motor casing, high-grade packaging, indoor decoration etc. relate to plastic industry use.
