Description
Technical field
The invention belongs to technical field of paint preparation, be specifically related to the impermeable coating that a kind of adhesion property is excellent.
Background technology
Chlorosulfonated polyethylene is a kind of special synthetic rubber [document 1: Ye Chunbao, rubber sources utilizes, and 3 (2000) 5.] with ozone weather-proof, resistance to, oil resistant, acid and alkali-resistance, the high comprehensive performance such as ageing-resistant, corrosion-resistant, adhesion is strong.Due to the performance that it is excellent, chlorosulfonated polyethylene is being widely developed and is utilizing, and is a kind of developing novel high polymer material.Its main application fields has: construction material, cable insulation material, auto parts and components, industrial product, coating, blend rubber are modified.
At present, the industrial process of chlorosulfonated polyethylene mainly has two kinds, ie in solution method and solid phase method [document 6: Yang Wei, Feng Weijia, Sun Xiuying, chemistry and bonding, (1997) 46. documents 7: Wang Peixi, China's chlor-alkali, (2001) 25.].Solwution method is also referred to as solvent method, with a long history for producing chlorosulfonated polyethylene, it is always up the main production method adopted both at home and abroad, solvent carbon tetrachloride has concurrently for advantages such as dissolubility are good, boiling point is low, easily separated, but relatively difficult owing to separation process being removed trace solvent and residual reaction gas from product, cause carbon tetrachloride discharge to produce to pollute.Carbon tetrachloride heavy damage ozone layer, is also a kind of greenhouse gases.
For overcoming disadvantages mentioned above, attempted later adopting fluidized bed process, and used substantial amounts of inorganic additive, but be not fully solved Problems existing yet, and owing to using inorganic filler too much, caused separation difficulty.Therefore, one-step technology does not have industrialization future.The raw material that solid phase stepwise method production technology uses is chlorinated polyethylene, only it need to carry out a step chlorosulfonation again just can obtain product, it is to avoid the chloridization process process that heat release is violent, is thus susceptible to control.But this technique needs specifically to produce equipment, the controllability of operating process still needs to be improved further.
Polyethylene powder coating has the general character of linear polymer, by can be changed into viscosity flow state after high temperature, the characteristic of original resin is recovered again after cooling, there is excellent flexible resistance, impact, electrical insulating property and resistance to chemical corrosion simultaneously, thick coating, price is low, is widely used in the application of daily living article, traffic guardrail, chemical industry equipment anticorrosion, auto parts machinery etc.；In recent years along with China's expanding economy, growth in the living standard, its demand grows with each passing day, but polythene thermoplastic powdery paints belongs to non-polar material, and coating is poor with the adhesion of metal base, limits its application development.
Summary of the invention
For problems of the prior art, it is an object of the invention to provide the impermeable coating that a kind of adhesion property is excellent, use inorganic acid ester as suspended solvents, chlorosulfonated polyethylene is produced by suspension process, thus preparing coating have prominent wearability, proof stress crack resistence, low-temperature flexibility be good and excellent heat resistance.
Technical scheme is as follows:
The impermeable coating that a kind of adhesion property is excellent, it is characterised in that specifically include following steps:

(2) chlorosulfonated polyethylene processed: take suspended solvents and chlorinated polyethylene powder according to weight ratio 1:5; chlorinated polyethylene powder is realized chlorosulfonation by dispersed with stirring in suspended solvents; pass in solution under inert gas shielding; add the benzoyl peroxide of 2-4% and the pyridine of 0.6-0.8%; control reaction temperature 70-80 ° of C, response time 40-50min, suspended solvents is recovered by filtration; material dewatering, to washings pH > 6, is then dried by filter cake use water cyclic washing；
(3) fusion-grafting pelletize: take bentonite base material and chlorosulfonated polyethylene mixing according to percentage by weight 3:1, add the antioxidant 1010 of oxidation diisopropylbenzene (DIPB), the phenolic resin of 2-4% and 0.3-0.5% that mixture weight percentage ratio is 0.3-0.5%, double screw extruder controls temperature be 150-160 DEG C and carry out melting graft reaction, extrusion pelletize.
Further, in described step (2), suspended solvents is that carbonic ester and phosphate ester are according to the weight ratio 2:3 mixture formed.
Further, in described step (2), noble gas is nitrogen or argon.
The using method of the impermeable coating that a kind of adhesion property is excellent, it is characterized in that, above-mentioned gained powdery paints is carried out application with electrostatic spray, 25-35min is toasted under 190-200 degree, then sample is put into heat-insulation soaking certain time in the hot water of 86-88 DEG C, complete cross-linking reaction, cool down film forming.
The invention have the benefit that
The present invention uses carbonate-based solvent safety non-pollution, is green and environment-friendly solvent, adopt suspension method chlorosulfonation technique solve solid phase method production process exists dust is many and reactor off-gas difficult treatment and the problem such as alkali consumption is big；Being conducive to when carrying out chlorosulfonation going deep into carrying out inside chlorinated polyethylene, react abundant, uniform, easily controllable, properties of product are stable, excellent.
The coating that the present invention prepares has prominent wearability, proof stress crack resistence, low-temperature flexibility be good and excellent heat resistance, suspended solvents enables thermoplastic molecular resin hydrolytic crosslinking itself, while increasing its corrosion resistance, also its adhesion property with bentonite base material is made to be greatly improved, the suspended solvents abundant recovery of method by direct isolated by filtration, cost declines.
The present invention adopts the rotating speed high-speed stirred of 1500rpm-2000rpm can be effectively prevented pore, slag inclusion phenomenon, gained coating carries out application with electrostatic spray, heat-insulation soaking certain time is put in hot water after baking, complete cross-linking reaction, cooling film forming, be suitable for large-scale industrial production, simple to operate efficiently.
