Background technology
As everyone knows; The rubber dam that elastomeric material is made is a kind of hydraulic structure; The checkdam that water (gas) inflation forms; Can be used for flood control, irrigate, generating, supply water, usefulness that ecoscape is built in retaining tide and city, the rubber floor covering that the public place is laid is because no antibiotic mildew-resistant algae-resistant function (general more than 2 months) in use for some time, because a large amount of black mildew of the etch of mould appearance; The colorful rubber dam that is used to control flood, block water, administer beautifying city, river course ecotope is after operation for some time; A large amount of blackish green liver moss mildews appears in the surface; Destroyed rubber item interior molecules structure like this, made the product appearance downgrade, aging resistance reduces; Need often to clean, expended a large amount of human and material resources.
Summary of the invention
For addressing the above problem, thereby the present invention provides a kind of antibiotic mildew-resistant algae-resistant to keep its visual appearance and inner quality, thereby not needing often to clean has saved antibiotic mildew-resistant algae-resistant elastomeric material of a large amount of manpower and materials and preparation method thereof.
Antibiotic mildew-resistant algae-resistant elastomeric material of the present invention; Wherein, Main rubber comprises tree elastomer, styrene-butadiene rubber(SBR), terpolymer EP rubber, X 050, paracril, chlorosulfonated polyethylene rubber, chlorinatedpolyethylene or arbitrary combination wherein, it is characterized in that: also comprise derosal, N-octyl group RH-893 and Diuron Tech.
The preparation method of antibiotic mildew-resistant algae-resistant elastomeric material of the present invention, wherein,
1 >, mixing fusion or back mixing fusion: derosal, N-octyl group RH-893, three kinds of materials of Diuron Tech are joined in the elastomeric material sizing material by the formula rate fusion; Fusion is in closed rubber kneading machine or back mixing machine, to carry out; 50 ℃-110 ℃ of the temperature of sizing material are admixed time 5-10 minute during fusion.
2 >, roll, extrude compound slice: the rubber unvulcanizate that fusion is good extrudes on rubber calender or film forcing machine has certain width in (general 0.5-1.5 rice), the film that certain thickness (general 0.4-20mm) length is not limit.40 ℃-90 ℃ of the temperature that calendering is extruded.
3 >, sulfuration flat board or drum vulcanizer sulfuration: film is vulcanized on sulfuration flat board or drum vulcanizer, process work in-process sulfide film or adhesive plaster.140-160 ℃ of sulfuration process temperature.
4 >, blanking moulding: will vulcanizate film or adhesive plaster and promptly be made into the antibiotic mildew-resistant algae-resistant elastomeric material by size blanking, the moulding of stipulating.
Beneficial effect of the present invention is: the compound ligand that in used elastomeric material, adds three kinds of mould inhibitors, antiseptic-germicide, anti-algae agent makes it have the antibiotic mildew-resistant algae-resistant function; Its mechanism of action is through destroying the cell structure of mould and algae; Stop metabolism; The activity that reduces mould and algae prevents or mould fungus inhibition and algae grows and breeding, thereby keeps its visual appearance and performance, do not need frequent cleaning, saved a large amount of manpower and materials.
Embodiment
Antibiotic mildew-resistant algae-resistant elastomeric material of the present invention; Wherein, Main rubber comprises tree elastomer, styrene-butadiene rubber(SBR), terpolymer EP rubber, X 050, paracril, chlorosulfonated polyethylene rubber, chlorinatedpolyethylene or arbitrary combination wherein, derosal, N-octyl group RH-893 and Diuron Tech, at first, derosal, N-octyl group RH-893, three kinds of materials of Diuron Tech is joined in the rubber dam sizing material by the formula rate fusion; Fusion is in closed rubber kneading machine or back mixing machine, to carry out; The sizing material temperature is 50 ℃-110 ℃ during fusion, and blending time 5-10 minute, (wherein; The add-on of compound ligand accounts for the heavy 0.3%-0.5% of elastomeric material sizing material); Secondly, the rubber unvulcanizate that fusion is good extrudes on rubber calender or film forcing machine has certain width in (general 0.5-1.5 rice), the film that certain thickness (general 0.4-20mm) length is not limit.40 ℃-90 ℃ of the temperature that calendering is extruded once more, are vulcanized film on vulcanizing press, process work in-process sulfide film or adhesive plaster.140-160 ℃ of sulfuration process temperature, last, promptly be made into the antibiotic mildew-resistant algae-resistant elastomeric material with vulcanizating size blanking, the moulding of film or adhesive plaster by regulation.
Above embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
