Description

A kind of high temperature resistant low toxicity mallear stria spray painting and preparation method thereof
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of high temperature resistant low toxicity mallear stria spray painting and preparation method thereof.
Background technology
The coating surface of mallear stria spray painting is uneven, has three-dimensional uneven hammer tone effect, can cover base material out-of-flatness Smooth, the defects of color and luster is uneven, ornamental strong, various colors, improve the aesthetic property and surcharge of product.Spirit is operated during construction It is living, simple, it is widely used in decorating the materials such as metal, glass, ceramics, but colour stability to be present poor for the spray painting of general category mallear stria, It is easy to change and insufficient in terms of heat-resisting quantity, it is general heat-resisting at 80 DEG C or so, at higher temperature and harsher corrosive environment can not be met Occasion.High temperature resistant spray painting refer to paint film more than 200 DEG C non-foaming, not efflorescence, be not cracked, do not fall off, it is allowed to have slight mistake Light, the special coating of suitable physical mechanical performance can be kept.It can meet that metal material can be under high temperature and harsh corrosive environment Operation, without oxide etch occurs, to reach the service life for extending high-temperature service.Meanwhile high temperature resistant spraying on the market Color is single, common to have high temperature resistant silver and high temperature black, it is difficult to meet market to the diversified demand of color.
In addition, from 2 1st, 2015 to coating impose the consumption tax and " 13 " planning in strengthen Ecological Civilization Construction, The key task of the adjusting and optimizing industrial structure, beautiful China Reconstructs is promoted, accelerate China's aerosol paint to low toxic and environment-friendly coating direction Transition.Spray painting（Also referred to as aerosol paint or hand-operated automatic paint spraying）By content, propellant, pressure vessel and the part of valve system four Composition.Product sheet has certain internal pressure as closed container after filling propellant and active ingredient, exist inhalator jar deformation and Two kinds of potential dangers of explosion.PORT OF TIANJIN " 8.12 " fire explosion causes 165 people to be murdered, the auspicious Hai Guojiwuliucang in explosion scene Contain second and third, four, five, six, eight, nine class dangerous material, including compressed liquefied gas, inflammable solid, liquid and oxidant With organic peroxide etc..The chemical plant institute inner oil sump car of Liaoyang one on the 15th of September in 2015 is natural.Harmful influence security incident is frequently sent out Worry is drawn in life, triggers us to aerosol products safety in production, storage, transport and the great attention using problem.
At present, at home and abroad disclosed hammer paint technology has a lot.If number of patent application is CN201210255388.0 A kind of high temperature resistant low-temperature quick-drying type hammer paint is disclosed, mainly passes through organic siliconresin, non-floating type aluminium powder, sec-Butyl Acetate, glass Glass powder, hammer agent and dimethylbenzene, solve the resistance to elevated temperatures, quick-drying and antiseptic property of existing hammer paint, contain in formula Dimethylbenzene toxic solvent, low toxic and environment-friendly requirement is not met, and color is single and does not refer to resistance to 500 DEG C of longer times or higher temperature When its technique effect；The number of applying for a patent CN200810211114.5 discloses a kind of environment protective polyurethanes hammer paint, mainly passes through Three components are mixed by certain weight ratio, have paint film bright-colored, and clean mark, hammer tone effect is good, and hardness of paint film is high, Without triphen, the characteristics of low VOC, but it does not refer to the technology effect of specific hammer tone effect, temperature tolerance and hammer paint colour stability Fruit.《Science Chinese》Periodical discloses " technical research of hammer paint resistance to elevated temperatures " paper, passes through self-cross linking type organosilicon Modified resin, non-floating type aluminium powder, glass dust, hammer agent, dimethylbenzene, sec-Butyl Acetate, obtain that there is excellent mallear stria outward appearance Effect and antiseptic property, can resistance to 500 DEG C of hammer paint for a long time, but it has that color is single and the toxic solvent containing dimethylbenzene lacks Fall into, its technique effect when also not referring to resistance to 500 DEG C of longer times or higher temperature.
As can be seen here, develop one kind can for a long time resistance to 600 DEG C of high temperature, rich in color and colour stability it is good, it is less toxic, safety be The high high temperature resistant low toxicity mallear stria spray painting of number is imperative.
