Abstract
The invention provides a dimethyl ether resistant rubber treatment method, wherein a rubber piece used on a position which contacts gas phase or liquid phase of dimethyl ether is separated from the gas phase or the liquid phase of the dimethyl ether by the film-forming treatment method, so that the effect of corrosion resistance is achieved. The dimethyl ether resistant rubber treatment method has the advantages that the dimethyl ether resistant rubber treatment method creates conditions for application of the dimethyl ether, can be used for producing dimethyl ether resistant products, and has convenient processing.
Description
Technical field
The present invention relates to a kind ofly prepare rete at rubber surface, to reach rubber dimethyl ether resistant corrosive purpose, it is applicable to heating or room temperature preparation rete.
Background technology
Dme (DME) wide material sources can be produced in a large number from raw materials such as coal, Sweet natural gas, coal-seam gas, biomass.As a kind of new green energy resource, the prospect of dme is very wide.Simultaneously, dme to the material of its cooperation, the performance of the rubber parts that uses at the position that contacts with the gas phase or the liquid phase of dme etc. has also proposed new adaptability requirement.
Dme is a kind of polar solvent, though metal there is not corrodibility, but can the multiple rubber of swelling, as paracril commonly used in pipeline, the equipment, viton etc.Rubber parts is for a long time with after dme gas phase or liquid phase contact, because oxygenizement, usually cause the phenomenon such as decomposition, dissolving, stripping of molecular breakdown, depolymerization and the Synergist S-421 95 of rubber, cause the corrosion of these materials or cause swelling, mechanical property is variation thereupon also, thereby causes it aging or damage, and can't normally use, threaten the safe operation of equipment, elastomeric material or the method for therefore studying dimethyl ether resistant have epochmaking using value.Existing dimethyl ether resistant corrosion rubber as perfluor ether rubber, costs an arm and a leg on the market, is unsuitable for applying, and how satisfying these new requirements becomes the current problem of researching and solving that presses for both at home and abroad.
Summary of the invention
The object of the present invention is to provide a kind of dimethyl ether resistant corrosive to handle the method for rubber.
The present invention seeks to be achieved through the following technical solutions:
1. clean: rubber parts is carried out oil removing, scrubbing, bad to prevent rete and rubber substrate sticking power;
2. oven dry or room temperature are dried: remove the moisture in the rubber parts, bubble in film process preventing;
3. preparation rubber rete: with spray, smear, methods such as brushing or dip-coating, on the surface that needs apply, apply one deck coating;
4. in baking oven internal heating film forming or drying at room temperature film forming.
According to the prepared coating of the present invention, cost is low, technology is easy, filming forms fast, and can be used for the rubber parts of different shapes, unlike material.
On the technique scheme basis, described rubber substrate can be a kind of or its synthetic rubber in natural rubber, paracril, ethylene-propylene rubber(EPR), polyisobutene and isoprene-isobutylene rubber, polyacrylic rubber, polyisoprene rubber, polybutene rubbers, viton, silicon rubber, trifluoropropyl siloxane, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, chloroprene rubber, polyether rubber, thiorubber, chlorinatedpolyethylene, chlorosulfonated polyethylene and the urethanes, but is not limited to above-mentioned rubber.
On the technique scheme basis, described coating is the dimethyl ether resistant material.
The method for treating rubber of dimethyl ether resistant of the present invention possesses following advantage: one, the method for treating rubber of dimethyl ether resistant, for Application of dimethyl ether has been created condition; Two, the rubberized method of dimethyl ether resistant of the present invention can be used for producing the dimethyl ether resistant product, processes very convenient.
Specific embodiment
Describe the present invention and preparation process thereof in detail below in conjunction with embodiment, but the present invention is not subjected to the qualification of following embodiment.
Embodiment 1:
Spray a kind of coating to rubber substrate spare surface, or rubber substrate is immersed in the coating, at room temperature drying and forming-film.
Embodiment 2:
Spray a kind of coating with high-pressure air to rubber substrate spare surface, in heat temperature drying in oven film forming, temperature: 140 ℃, the time: 10 minutes.
Embodiment 3:
Rubber substrate is immersed in the coating, in heat temperature drying in oven film forming.
Claims (3)
1. a dimethyl ether resistant corrosive method for treating rubber is at rubber parts surface preparation rete, and the position that rubber parts is contacted with the gas phase or the liquid phase of dme isolates.
2. rubber parts according to claim 1, it is characterized in that: described rubber is a kind of or its synthetic rubber in natural rubber, paracril, ethylene-propylene rubber(EPR), polyisobutene and isoprene-isobutylene rubber, polyacrylic rubber, polyisoprene rubber, polybutene rubbers, viton, silicon rubber, trifluoropropyl siloxane, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, chloroprene rubber, polyether rubber, thiorubber, chlorinatedpolyethylene, chlorosulfonated polyethylene and the urethanes, but is not limited to above-mentioned rubber.
3. rete according to claim 1 is characterized in that: being used for film forming coating is the dimethyl ether resistant material.
