Abstract
The invention relates to a highly transparent unsaturated polyester primer with low cost, which contains ingredients in weight proportion as follows: 60 to 80 unsaturated polyester resin, 0.1 to 0.5 antifoaming agent, 0.1 to 0.5 wetting dispersant, 3 to 8 zinc stearate, 0.2 to 0.5 anti-settling agent, 5 to 25 transparent powder, 0.2 to 0.5 leveling agent, and 4 to 14 styrene. The reparation of the highly transparent unsaturated polyester primer comprises the following steps: adding the unsaturated polyester resin, the antifoaming agent and the wetting dispersant in a container sequentially, conducting dispersion for 3 to 5 minutes at 500RPM; adding the anti-settling agent, the zinc stearate and the transparent powder while stirring, conducting dispersion for 15 to 20 minutes at 1200RPM to fineness of less than or equal to 30Mum; adding the leveling agent and the styrene, conducting dispersion for 10 minutes at 500RPM, and conducting filtering, thus obtaining the highly transparent unsaturated polyester primer. When in use, the primer, ethyl methyl ketone peroxide, thinner and cobalt naphthenate are mixed in the weight proportion of 100:1-2:30:1-2; and the thinner is mixed by dimethylbenzene, acetic ether and styrene in the weight proportion of 50:20:30. In the primer, the transparent powder is adopted to replace resin with the weight of 5 to 25 percent, thus not only obviously lowering cost, without influencing the transparency, but also improving the filling capacity and the hardness of paint; and a paint film can not turn white.
Description
Technical field
The present invention relates to unsaturated polyester priming paint, particularly a kind of highly transparent unsaturated polyester priming paint and preparation method thereof and method of use.
Background technology
Existing conventional unsaturated polyester priming paint on the market, main raw material(s) is resin and solvent in its prescription, and these all belong to refinery products, and price is all higher, has just caused the integral formula cost of unsaturated polyester priming paint high.Profit is more and more lower because rising steadily of oil price drives the refinery products substantial appreciation of prices, and the cost of feasible paint is increasingly high, and this area hopes guaranteeing that the high-quality while of priming paint can reduce cost.
Summary of the invention
The technical problem that the present invention will solve provides a kind of priming paint of highly transparent unsaturated polyester cheaply and preparation method thereof and method of use.
For addressing the above problem, the present invention provides a kind of highly transparent unsaturated polyester priming paint, is processed by the component of following weight proportion:
Said unsaturated polyester resin is the sky dryness, and acid number is 10-30, admittedly contain the resin liquid for 72%-78%.
Said transparent powder is silica weight percentage composition＞70%, contain the white powder of crystal water.
Said Zinc Stearate is zinc content>=11% weight percent, the fines of moisture content≤0.5% weight percent.
Said wetting dispersing agent is the HMW unsaturated polyester carboxylic acid solution of organic modified polyorganosiloxane, and model is Tego610S.
Said anti-settling agent is that a kind of superfine, specific surface area are 220m
2The hydrophobic type silicon-dioxide of/g, model are A200; Said flow agent is the good polyacrylate solution of consistency, and model is BYK358.
Said skimmer is the polymers soln with silicone end group, and model is Tego986.
Said each composition weight proportioning is:
The present invention also provides a kind of method for preparing said highly transparent unsaturated polyester priming paint simultaneously; It is characterized in that: get unsaturated polyester resin, skimmer, wetting dispersing agent in the component according to weight proportion; And adding container successively, 500PRM disperses 3-5 minute to even; Add anti-settling agent, Zinc Stearate, transparent powder more while stirring by weight ratio, after adding, 1200RPM disperses 15-20 minute to fineness≤30 μ m; Add flow agent, vinylbenzene then by weight ratio successively, 500RPM disperses 10 minutes to evenly, filters and promptly gets described highly transparent unsaturated polyester priming paint.
The present invention also provides the method for use of said highly transparent unsaturated polyester priming paint simultaneously; It is characterized in that at first, by unsaturated polyester priming paint: methylethyl ketone peroxide: thinner: the weight proportion of cobalt naphthenate=100: 1-2: 30: 1-2 is got said components; And mix; Carry out spraying application then, sprayed air-dry 24 hours, promptly get the paint film of highly transparent unsaturated polyester priming paint; Wherein, described methylethyl ketone peroxide, the addition of cobalt naphthenate changes with temperature is different, when envrionment temperature more than 30 degrees centigrade the time, addition is 1% of priming paint weight; When envrionment temperature during at 20-30 degree centigrade both additions be 1.5% of priming paint weight; Both additions are 2% of priming paint weight when envrionment temperature is lower than 20 degrees centigrade; Said thinner, mixed by the component of following weight proportion and to constitute:
YLENE 50
Vinyl acetic monomer 20
Vinylbenzene 30.
Highly transparent unsaturated polyester priming paint of the present invention; Used a kind of transparent powder that can partly replace resin in its component; The resin that in prescription, replaces 5%～25% weight percentage does not influence the transparency basically, but also has improved the fillibility and the hardness of paint.This kind transparent powder only need disperse just can reach in 10～15 minutes the fineness requirement of 30 μ m in the resin liquid high speed.And the price of this kind transparent powder is merely about 10% of resin price, so obviously reduced formulation cost.The prescription of prior art basically all is made up of separately resin, and cost is higher; Or resin adds talcum powder and forms, and cost has reduced, but the difference that the transparency just becomes.And used transparent powder not only reduces cost but also does not influence the transparency among the present invention.Because contain certain crystal water in the transparent powder; When doing prescription, may cause the problem of turning white of lacquer; So general technician can not select transparent powder for use owing to turning white of transparent powder; And among the present invention since the higher dispersion agent of acid number and contain and gather silica, experiment shows can prevent turning white of paint film.
