The present invention relates to the preparation method of SBR sponge matrix material.
Background technology:
SBR sponge matrix material is widely used in fields such as physical fitness, footwear material, bag material, medical protector, aquatic sports.Domestic existing SBR sponge matrix material main raw material is that styrene-butadiene rubber(SBR) and other raw material ratio mix through processing, forms sponge through the foaming of vulcanizing press High Temperature High Pressure post vulcanization again.The common shortcomings such as anti-aging is indifferent, easy firing, heat-shrinkable is big, tensile strength is low, compression deformation rate is big that exist of domestic existing SBR sponge matrix material.Usually its prescription is a radix with the SBR100 mass parts, allocate weighting agent 151~157 mass parts into by mass parts, tenderizer 53~55 mass parts, strengthening agent 26~26.3 mass parts, processing aid 15~16 mass parts, vulcanizing agent and auxiliary agent 2~2.5 mass parts, promoting agent 8~9 mass parts, dispersion agent 3~4 mass parts, whipping agent 13~18 mass parts.
SBR sponge matrix material master glue styrene-butadiene rubber(SBR) 1502, weighting agent light calcium carbonate and carclazyte, tenderizer is a RUBBER PROCESS OIL with oil generally, strengthening agent is generally used carbon black, and processing aid white factice, vulcanizing agent are generally used Sulfur, vulcanization aid is generally used thiazole accelerator, promoting agent is generally used stearic acid and zinc oxide, and dispersion agent is generally used AFLUX-42, and whipping agent is generally with DPT or AC.
With following example existing general making method is described: with 100 parts in 1502 glue, carclazyte 82.6,73.3 parts of fine particle calcium carbonates, 2.2 parts of Sulfur and auxiliary agents, 54.4 parts of treated oils, 26.1 parts of carbon blacks, 15.2 parts of white factices, 2 parts of stearic acid, 6.5 parts in zinc oxide, 3 parts of AFLUX-42 dispersion agents drop into internal mixer sequentially and mix and expect that the machine of beginning to pratise begins to pratise to the broad logical postcooling 12hr of 10min under 15min to 120 ℃, again with the machine preheating 6min forcing machine slice of beginning to pratise, earlier using 1800T oil press, vapor pressure is about 3 kilograms, carries out one step cure about time 30min; Oil press vapor pressure with 300T is about 6 kilograms at last, carries out the post vulcanization foaming about time 20min.Goods are after testing: tensile strength is 2 kilograms of f/cm 2, elongation is 210%, 1.33 kilograms of f/cm of tear strength 2, density is 0.219g/cm 3, percent thermal shrinkage (70 ℃ 24hr) are MD:4%; CD:5%, compression deformation rate are that (23 ℃ is 30% 22hr), and goods were parked after 7 days obvious aging characteristics, and naked light leaves and can not extinguish and burning always after lighting with naked light.
In sum, domestic existing SBR sponge matrix material exists anti-aging indifferent, easy firing, shortcoming such as heat-shrinkable is big, and tensile strength is low, and compression deformation rate is big.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of New type of S BR sponge matrix material and preparation method thereof is provided.
SBR sponge composite-material formula of the present invention is: with SBR rubber 1502100 mass parts is radix, allocating terpolymer EP rubber (EPDM) into by mass parts is 30~50 parts, 170~180 parts of weighting agent light calcium carbonates, 28~30 parts of carclazytes, 23~25 parts of strengthening agent N330 black smokes, 67~70 parts of tenderizer naphthenic oils, dispersant A FLUX-42 is 2.7~3 parts, 2~2.3 parts in oxidation inhibitor, 2.5~2.8 parts of protection waxes, 2.7~2.8 parts of stearic acid, 9 parts~9.5 parts in zinc oxide, 5~6 parts of vulcanizing agent and auxiliary agents thereof, 19~21 parts of AC whipping agents, 70~73.5 parts (wherein clorafin is 36~39 parts for fire retardant, 34~34.5 parts of antimonous oxides), the alcohols processing aid is 2.5~2.8 parts.
Preparation method of the present invention is: with SBR rubber 1,502 100 mass parts is radix, allocating terpolymer EP rubber (EPDM) into by mass parts is 30~50 parts, 170~180 parts of weighting agent light calcium carbonates, 28~30 parts of carclazytes, 23~25 parts of strengthening agent N330 black smokes, 67~70 parts of tenderizer naphthenic oils, dispersant A FLUX-42 is 2.7~3 parts, 2~2.3 parts in oxidation inhibitor, 2.5~2.8 parts of protection waxes, 2.7~2.8 parts of stearic acid, 9 parts~9.5 parts in zinc oxide, 5~6 parts of vulcanizing agent and auxiliary agents thereof, 19~21 parts of AC whipping agents, 70~73.5 parts (wherein clorafin is 36~39 parts for fire retardant, 34~34.5 parts of antimonous oxides), 2.5~2.8 parts of alcohols processing aids drop into internal mixer sequentially and mix and expect that the machine of beginning to pratise begins to pratise to the broad logical postcooling 12hr of 10min under 15min to 120 ℃, again with the machine preheating 6min forcing machine slice of beginning to pratise, and the first 1800T oil press of using, vapor pressure is about 3 kilograms, carries out one step cure about time 30min; Oil press vapor pressure with 300T is about 6 kilograms at last, carries out the post vulcanization foaming about time 20min.
The invention has the advantages that: present method is at the more above-mentioned performance deficiencies of domestic SBR sponge matrix material, develops maximum range under the prerequisite that guarantees its property and reduces defective on its performance.For obtaining this effect, we find that EPDM has outstanding ageing resistance (ozone resistance, thermally-stabilised, heat-resistant aging, anti-day marquis's property, chemical-resistant resistance, oil resistance), EPDM is that saturated nonpolar is not from reinforcement simultaneously, can absorb a large amount of oil and fillers makes its properties influence little, therefore in the traditional sponge composite-material formula of SBR, add the fine above-mentioned defective of improving SBR sponge matrix material of EPDM energy, allocating fire retardant simultaneously into makes goods possess strong flame retardant resistance and static resistance, make the SBR sponge can not cause that the incendiary probability is extremely low because of static sparking at compounding machine (rigging machine) compound tense.
