Abstract
The invention belongs to the technical field of rubber and plastic gaskets, and in particular discloses a formula and a manufacturing method of a wearing-resistant rubber and plastic gasket. The wearing-resistant rubber and plastic gasket can be prepared from natural rubber, cis-polybutadiene, high styrene, high wearing-resistance carbon black, an anti-aging agent D, an anti-aging agent A, zinc oxide, an accelerant NOBS and sulfur powder through plastifying, curing, internal milling, open milling and vulcanizing processes. The rubber and plastic gasket disclosed by the invention has excellent wearing resistance, comprehensive mechanical property and excellent low-temperature property.
Description
Technical field
The present invention relates to rubber and plastic packing ring technical field, disclose specifically formula of a kind of wear resistance rubber and plastic packing ring and preparation method thereof.
Background technology
The rubber and plastic packing ring is a kind of very common part, be widely used in various components of machine, be mainly used to buffering, regulate, protection waits effect, it is exactly reason like this, causing the rubber and plastic packing ring is to change one of part the most frequently in engineering goods, also because this reason, just require the rubber plastic pad circle need to possess higher elasticity, plasticity, toughness and certain rigidity, simultaneously also very high to the requirement of wear resistance, reach test repeatedly through the many years of experience that rubber-plastics material is produced, develop a kind of rubber and plastic packing ring with comprehensive mechanical performance, it is a kind of wear resistance rubber and plastic packing ring.
Summary of the invention
Purpose of the present invention just is to provide the super wear-resisting rubber-plastics packing ring that a kind of performance perameter is good.
Realize that the technical scheme that above-mentioned purpose of the present invention adopts is:
A kind of formula of wear resistance rubber and plastic packing ring, the natural rubber by 40%～45%, 10%～15% cis-1,4-polybutadiene rubber, 13%～16% high-phenylethylene, 10%～18% high wear-resistant carbon black, 4%～5% antioxidant D, 1%～2% antioxidant A, 8%～21% zinc oxide, 2%～4% accelerant NOBS and 2%～3% SULPHUR POWDER form.
A kind of preparation method of wear resistance rubber and plastic packing ring comprises the following steps:
Plasticate: 10-25 minute plasticates natural rubber at the temperature of 60-75 ℃;
Slaking: the rubber after plasticating is placed in to slaking 10-15 hour under the normal temperature of 20-25 ℃;
Banburying: all raw materials except SULPHUR POWDER are added in Banbury mixer to mixing 15-20 minute at the temperature of 110-115 ℃;
Open refining: after the raw material after banburying adds SULPHUR POWDER mixing at the temperature of 40-45 ℃, by sheet under specification requirement;
Sulfuration: be that under 140-150 ℃, the pressure condition that is 15-18Mpa, sulfuration obtains a kind of wear resistance rubber and plastic packing ring in 20-25 minute in temperature by the conveying belt tablet of specification.
The prepared a kind of wear resistance rubber and plastic packing ring of the present invention compared with prior art has the following advantages: one, because the material that forms this rubber and plastic packing ring has comprised suitable high-phenylethylene and the high wear-resistant carbon black of ratio, make prepared conveying belt there is certain hardness, and can meet its wear-resisting performance; Its two, because the material forming this conveying belt has comprised zinc oxide, make this rubber and plastic packing ring physical strength be increased dramatically.
