Description
Technical field
The invention belongs to paint field, a kind of heat-proof combustion-resistant powdery paints for gas cooker surface layer and
Its preparation method.
Background technology
Progress and the development of modern industry along with modern science and technology so that problem of environmental pollution becomes day by day to dash forward
Going out, the environment that it depends on for existence to the mankind itself and the mankind causes threat greatly.Traditional coating was either manufacturing
All can produce substantial amounts of poisonous and hazardous waste gas and waste water in journey or in using work progress, they can be to environment, air
And water resource pollutes, especially solvent based coating, work progress can discharge VOC (VOC) to big
In gas, its amount has reached more than 50% and has caused serious second time to pollute.This problem causes the attention of many industrial countries.
Powdery paints obtains in recent years as a class environmental type coating in terms of various fields particularly coated metal
It is widely applied.Powdery paints is often using organic resins such as epoxy, polyester, acrylic acid, polyurethane as matrix, due to by matrix
The impact of resin self structure and restriction, these conventional powdery paints also exist weak point in some performances, and result in should
The limitation used.Compared with common organic resin, organic siliconresin have the most excellent heat-resisting, weather-proof, resistance to water and
Electrical insulation capability.Powdery paints uses organic siliconresin, its thermostability and weatherability can be improved, but use merely organosilicon
Resin exists expensive, to problems such as base material poor adhesive force.Therefore, often utilize organic siliconresin other organic resins modified,
The advantage of organic siliconresin He other organic resins can be combined, make up mutual deficiency, improve paint film weather-proof, heat-resisting
Etc. performance, obtaining the powdery paints of excellent performance, this is also an effective way of development functional powder coating.But due to
Organic siliconresin differs greatly with the solubility parameters of organic resin, and the compatibility is poor, and in the case of directly mixing, organosilicon has excessive
Occur as, at surface enrichment, be susceptible to microphase-separated.And the appearance of microphase-separated, to the modified hardness of resin, stability and
Mechanical performance all has a great impact, and the overall performance of final film is bad.
Heat Resistant Powder Coatings can be widely applied to the row such as electrical equipment, metallurgy, oil, aviation field, chemical industry, medicine, food
The various high temperature resistant equipment of industry is (such as: oven, warm-air drier, high-power lamp decoration, caliduct, automobile and motorcycle silencer, height
Temperature stove, chimney etc.).Although the relatively oil paint environmental protection of existing Heat Resistant Powder Coatings, but owing to its cost is the highest and needs height
Temperature solidification (minimum 230 DEG C × 20 minutes of condition of cure) limits it and promotes the use of.
Developing low-cost normal temperature cure Heat Resistant Powder Coatings can make the powdery paints of environmental protection replace paint to be applied to above-mentioned
Various high temperature resistant equipment, have very much market.
