Description
Technical field
The invention belongs to the chemical building material technical field, in particular a kind of high temperature resistant adeciduate dope layer coating and preparation method thereof.
Background technology
Corrosion-resistant degree and service requirements by its coating rete are divided into universal and heavy anti-corrosive type two classes usually.Protective system is that the departments such as modern industry, traffic, the energy, oceanographic engineering use a kind of coating very widely.Heavy-duty coating refers to relatively conventional protective system, can use in relatively harsh corrosive environment, and have a class protective system that can reach than the conventional longer protection period of protective system.It is reported, national heavy-duty coating developmental level how, and coating performance how, is the important sign of a national coating scientific and technological level.Just at present, protective system is as important directions of Chinese paint industry development, and its prospect is can predict bright.Along with the high speed development of the industries such as Chinese transportation, the energy, building, certainly will achieve further developing of Chinese protective system industry.At present, Chinese coating technology innovation is continuous, and national consuming capacity strengthens increasingly, and the coating of China usage quantity per capita also increases year by year.According to statistics, 7.2 kilograms of weight of coated paint per capita in 2010, the building coating usage quantity is 2.6 kilograms per capita, and cities and towns building coating usage quantity per capita are 5.5 kilograms, are respectively 6 times, 4 times, 4.6 times of calendar year 2001.Cities and towns per capita building coating usage quantity speedup higher than building coating speedup per capita.Consider foreseeable future, along with the Re-search on Urbanization process is accelerated, the urban population speedup will be much larger than the population speedup, so Chinese weight of coated paint room for promotion is worth the imagination.In recent years, along with improving constantly of coating property, the human consumer also constantly promotes the degree of recognition of coating, add coating for the finishing material such as stone material, ceramic tile, with the obvious advantage at aspects such as energy consumption, costs, therefore in the architecture inside and outside decoration field, the coating consumption is increasing, and popularity rate is more and more higher.Chinese unit completed floor space building coating fraction of coverage reached 4.6 kilograms every square metre in 2010, was 2.3 times of calendar year 2001.
Epoxyn is that a kind of use is historical for a long time, purposes utmost point tackiness agent widely.Waterborne epoxy adhesives can be divided into water-soluble and the large class of water-latex type two.The former is owing to can not preparing the high solids content product, and water-content is high, moisture evaporation difficulty, and energy consumption is large, seldom uses as tackiness agent.And water-latex type can be accomplished high solids content, low viscosity, and moisture evaporation is easy, and easy construction so development is very fast, obtains using more and more widely.Waterborne epoxy adhesives is through the research and development of decades, and formula and manufacturing technology are updated, and kind is on the increase, and Application Areas constantly enlarges.But to can not show a candle to application of paints so extensive for the tackiness agent take epoxy resin latex as raw material up to now, and the more successful application of waterborne epoxy adhesives is mainly building field.
Nowadays improving constantly along with people's living standard, quality of life there has been deeper pursuit, being coated with in the room expected that the air outside the room all has higher requirement, the life of green low-carbon becomes the inexorable trend of whole world development already, the development of also just complying with society that each manufacturing enterprise will do now.More difficult although start, but lay a solid foundation for coatings enterprises sound development in the future.
Select paint in household, most people are concerned about most or environmental issue.The most expensive not necessarily best of coating price, equally also good coating of a lot of its real mass of coating without reputation is arranged on market now, nowadays some very loud brands of reputation on market, it is not the very high product of scientific and technological content, just stirred by " a bite cylinder, two rods " originally and build up, this is the fact that a lot of people have known.Although the certain quality of the coating of famous brand is pretty good,, the human consumer should be known in so-called famous brand, is to pile out by advertising fee, so after all,the wool still comes from the sheep's back, price has also got on naturally.
Summary of the invention
A kind of high temperature resistant adeciduate coating, it is characterized in that it is by modified Teflon (PTFE) water-based resin 40-70 part, high-temperature resisting pigment 10-30 part, fluoro-resin additive 1-5 part, tensio-active agent 1-5 part, 20～45 parts of 0.8～2.0 part of UV light absorber uv327,1.0～2.5 parts of promotor, face, filler, 5～15 parts of thinners, flow agent 0.1～0.4, wear resistant filler 20-40 part form.
High temperature resistant adeciduate coating of the present invention, modified Teflon wherein (PTFE) water-based resin 40-50 part, high-temperature resisting pigment 10-20 part, fluoro-resin additive 1-3 part, tensio-active agent 1-3 part, 20～30 parts of 0.8～1.0 part of UV light absorber uv327,1.0～2.5 parts of promotor, face, filler, 5～10 parts of thinners, flow agent 0.1～0.2, wear resistant filler 20-30 part.
Tensio-active agent is the molecule that is formed by two kinds of distinct particles, and a kind of particle has extremely strong lipophilicity, and is another kind of have extremely strong wetting ability.After being dissolved in the water, tensio-active agent can reduce the surface tension of water, and improves the solubility of organic compound.Tensio-active agent scope very extensive (positively charged ion, negatively charged ion, nonionic and both sexes) for concrete the application provides several functions, comprises foaming effect, surface modification, cleaning, emulsion, rheology, environment and healthy protect.Tensio-active agent is used as performance additive in many industry formulas, as individual and home care, and in countless industrial application: metal treatment, industry cleaning link, oil production, agricultural chemicals etc.
The technical indicator of the high temperature resistant adeciduate coating of the present invention is as follows:
1, viscosity not: very thin film also demonstrates well not adhesion property.
2, thermotolerance: have good heat-resisting and low temperature tolerance characteristics.Short period of time can be high temperature resistant to 300 ℃, generally can use continuously between 240 ℃～260 ℃, has significant thermostability, and it can be worked and not embrittlement under freezing temp, does not at high temperature melt.
3, sliding: when load is slided, frictional coefficient changes, and numerical value is only between 0.05-0.15.
4, moisture resistance: film coated surface does not get wet and oil, also is difficult for being stained with solution during production operation, as is stained with a small amount of dirt, and simple wiping can be removed.Stop time is short, saves man-hour and can increase work efficiency.
5, wearability: under high capacity, have good wear resisting property.Under certain load, possesses wear-resistant and inadhesive two-fold advantage.
6, erosion resistance: Teflon is corroded by medicine hardly, can protect part to avoid suffering the chemical corrosion of any kind.
7, safety performance: because the solid constituent of this coating is nontoxic, do not contain ammonium perfluorocaprylate, form technique reasonable, so coating is nontoxic, is widely used in cooker, medicine, food product containers etc.
