Abstract
The invention relates to self-vulcanized rubber and a processing method and an application method thereof. The service performance of the rubber support can be restored on the site without lifting the bridge with a jack or limiting the road traffic. The self-vulcanized rubber is prepared through thoroughly mixing adhesive cement and vulcanizing agents and curing in the air, wherein the adhesive cement comprises chlorosulfonated polyethylene rubber, magnesium oxide, titanium dioxide powder, clay, microcrystalline wax, ultraviolet absorbers, capryl acetate and n-butanol; and the vulcanizing agents comprise epoxy resin, hydrogenated rosin, vulcanization accelerator and acetone. The self-vulcanized rubber is applied in repair and maintenance of rubber products which has ageing phenomenon, such as rubber supports. Although the self-vulcanized rubber can only form physical coupling, the coupling strength is very high, and the self-vulcanized rubber can not easily depart from the body of the rubber product, and can be used for reliable protection with sunlight resistance, no cracking, no discoloration, high extension rate and acid and alkali resistance. Moreover, the self-vulcanized rubber of the invention has the advantages of rapid curing, high adhesion, good mechanical properties, good aging resistance and the like. The operation for application is simple, and the cost is less than 1 percent of the cost for support replacement.
Description
Technical field
The present invention relates to a kind of prescription, working method and the application method aspect the maintenance rubber item thereof of preventing rubber layer of the bearing of reduced rubber at the scene use properties.
Background technology
Rubber support mainly is to transmit the load on bridge top and regulate relative displacement between superstructure and the substructure, and it mainly leans on is that translation and rotation are regulated in the distortion of rubber.Because the rubber support quality is uneven on the market; And most of rubber supports are based on natural rubber, and natural rubber is unsaturated non-polar rubber, and performance is more active, with airborne hot oxygen and light oxygen the chemistry reflection take place easily; Reasons such as the site operation technology is lack of standardization cause rubber support that serious be full of cracks and aging in use takes place, and as untimely processing, rubber support will be lost functions of use, cause bridge deformation, cause serious consequence.
At present, when meeting the problems referred to above, generally the carrier on the rubber support need be jack-uped, change.In fact, this rubber support only is to have surface imperfection, and its internal performance satisfies service requirements fully.But as timely treat surface defective, its internal performance promptly can worsen.
Summary of the invention
The present invention is directed to above technical barrier, provide a kind of the needs at the scene that bridge is held up with screw block, need not limit self-vulcanized rubber, working method and application that road gets final product reduced rubber bearing use properties.
Self-vulcanized rubber of the present invention by rubber cement and vulcanizing agent uniform mixing after, form in air set,
The component that comprises in the described rubber cement is by weight: 100 parts of chlorosulfonated polyethylene rubbers, magnesium oxide 15-25 part, titanium dioxide 5-15 part, potter's clay 5-15 part, Microcrystalline Wax 0.3-2 part, UV light absorber 0.1-1 part, acetic acid own fat 400-800 part and propyl carbinol 50-100 part;
The component that comprises in the described vulcanizing agent is by weight: Resins, epoxy 20-30 part, staybelite 5-20 part, vulcanization accelerator 1-9 part and acetone 50-80 part.
The working method of self-vulcanized rubber of the present invention is,
The working method of described rubber cement is:
1), earlier chlorosulfonated polyethylene rubber is plasticated with mill, thin-pass 8-12 time is glue, parks 12-24 hour, and is stand-by;
2), magnesium oxide, titanium dioxide, potter's clay, Microcrystalline Wax, UV light absorber are added in the stand-by chlorosulfonated polyethylene rubber, use mill mixing, make the film of 0.5-1mm again, park 12-24 hour, stand-by;
3), with film chopping, add and be equipped with in the reflection still of the own fat of acetic acid, propyl carbinol, at 15-40 ℃ of following stirring and processing 24-48 hour, be the rubber cement shape of thickness liquid state, make rubber cement;
The working method of described vulcanizing agent is: Resins, epoxy, staybelite, vulcanization accelerator and acetone are added in the reactor mix, stirring and processing 24-48 hour at normal temperatures, make vulcanizing agent.
The application method that self-vulcanized rubber of the present invention is safeguarded rubber support is:
1), rubber support surface dirt earlier that the working-yard is aging and be full of cracks is removed;
2), use sand mill sand paper the rubber support surface sand milling of aging and be full of cracks;
3), aging and be full of cracks rubber support surface cleaning is clean after with sand milling with acetone;
4), rubber cement and vulcanizing agent are pressed 4-8: 1 weight ratio uniform mixing gets latices after the mixing;
5), latices is coated on the rubber support surface that cleans up, to be dried after, apply next time, until coat-thickness to 1.5-2mm.
Self-vulcanized rubber of the present invention is mixed by A (rubber cement), two kinds of materials of B (vulcanizing agent), wherein the A material is material of main part with the chlorosulfonated polyethylene rubber, add and have magnesium oxide fire-retardant, stabilization, titanium dioxide with reinforcement, anti-aging, filling effect, the potter's clay of enhanced shine, put aged Microcrystalline Wax and UV light absorber, and adopt own fat of acetic acid and propyl carbinol jointly as solvent, to improve synergistic effect, be convenient at the scene with after the B material mixes, can promote mechanical property, anti-aging of cured glue body etc. to greatest extent.With Resins, epoxy, staybelite and usefulness, can greatly increase the sticking power of cured glue body in the B material; Wherein vulcanization accelerator is preferably selected M type and ZDC type, and by 1: the mixed of 2-5 is used, and can further improve the curing speed under the normal temperature.Be applied to keep in repair, safeguard that rubber support etc. has on the rubber article of catabiosis, although be a kind of connection of physical angle, it is very big that it connects fastness, is difficult for breaking away from the body of rubber item; Under sun exposure, sun-resistant, do not ftracture, nondiscoloration, percentage of elongation reaches acid and alkali-resistance greatly; Thereby can protect rubber item reliably.Self-vulcanized rubber of the present invention has characteristics such as quick solidifying, sticking power height, good mechanical property, resistance to deterioration be good; Simple to operate, with low cost, cost is not enough changes 1% of bearing.
