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 the 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 to be main with tree elastomer, and tree elastomer is unsaturated non-polar rubber, and performance is more active, with airborne hot oxygen and light oxygen chemistry take place easily and reflect; 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 like 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 need the carrier on the rubber support be jack-uped, change.In fact, this rubber support only is to have surface imperfection, and its internal performance satisfies request for utilization 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 and need bridge not held up with screw block at the scene, 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 said rubber cement is by weight: 100 parts of chlorosulfonated polyethylene rubbers, Natural manganese dioxide 15-25 part, white titanium pigment 5-15 part, potter's clay 5-15 part, Microcrystalline Wax 0.3-2 part, UV light absorber 0.1-1 part, acetic acid is ester 400-800 part and propyl carbinol 50-100 part;
The component that comprises in the said vulcanizing agent is by weight: epoxy resin 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 said rubber cement is:
