Abstract
The invention discloses composite powder for rubber. The composite rubber is prepared from the following raw materials in parts by weight: 60-70 parts of calcium carbonate, 30-50 parts of diatomite, 1.5-2 parts of a cross-linking agent TAC, 0.4-0.6 part of aluminum nitride, 3-6 parts of antimony trioxide, 1-2 parts of an antioxidant DLTP, 3-6 parts of an NDZ-401 titanate coupling agent, 1-2 parts of dimethyl phthalate and 0.5-0.7 part of dioctyl adipate.
Description
Technical field
The present invention relates to rubber and make field, is exactly a kind of composite granule for rubber.
Background technology
Existing rubber item stopping composition used mainly plays strengthening action, increases the strength property of rubber.The electrodeless powder kind of existing rubber filling is single, acts on singlely, can't meet multiple demands.
Summary of the invention
The object of the present invention is to provide a kind of can play simultaneously fire-retardant, anti-aging, the composite granule for rubber of strengthening action.
Above-mentioned purpose realizes by following scheme:
A kind of composite granule for rubber, it is characterized in that: it is that raw material by following weight parts makes: calcium carbonate 60-70, diatomite 30-50, linking agent TAC 1.5-2, aluminium nitride 0.4-0.6, antimonous oxide 3-6, anti-oxidant DLTP 1-2, NDZ-401 titanate coupling agent 3-6, dimethyl phthalate 1-2, Octyl adipate 0.5-0.7.
Described a kind of composite granule of calcium carbonate for rubber, is characterized in that, the preparation method is:
(1) diatomite, is taken out after 1-2 hour in calcining under 400-500 ℃, cooling, grind to form nanometer powder, obtain the nanometer calcined diatomite standby;
(2) by calcium carbonate after 200-300 ℃ of lower sintering 1-2 hour, take out coolingly, obtain calcination of calcium carbonate, standby;
(3) after will all the other raw materials mix by weight except diatomite, calcium carbonate, add suitable quantity of water, under 30-35 ℃, stir 15-25 minute, obtain modification liquid, finally nanometer calcined diatomite and calcination of calcium carbonate are mixed, then add modification liquid, under 40-50 ℃, stir 20-30 minute, dry again, wear into nanometer powder, obtain.
Beneficial effect of the present invention is: it is good that the composite granule that the present invention prepares is manufactured adaptability to rubber, and intensity is high, stable performance, and flame-retardant anti-aging, high temperature resistant.
Embodiment
A kind of composite granule for rubber, it is that raw material by following weight parts (kg) makes: calcium carbonate 70, diatomite 50, linking agent TAC 2, aluminium nitride 0.6, antimonous oxide 4, anti-oxidant DLTP 2, NDZ-401 titanate coupling agent 5, dimethyl phthalate 2, Octyl adipate 0.7.
Described a kind of composite granule of calcium carbonate for rubber, the preparation method is:
(1) diatomite, is taken out after 2 hours in calcining under 500 ℃, cooling, grind to form nanometer powder, obtain the nanometer calcined diatomite standby;
(2) by calcium carbonate in 280 ℃ of lower sintering after 1 hour, take out coolingly, obtain calcination of calcium carbonate, standby;
(3) after will all the other raw materials mix by weight except diatomite, calcium carbonate, add suitable quantity of water, under 35 ℃, stirred 20 minutes, obtain modification liquid, finally nanometer calcined diatomite and calcination of calcium carbonate are mixed, then add modification liquid, under 50 ℃, stirred 30 minutes, dry again, wear into nanometer powder, obtain.
With the present embodiment gained composite granule, terpolymer EP rubber is carried out to reinforcement, calcium carbonate: terpolymer EP rubber=50:100, the gained material carries out performance test
Tensile strength is 17.8Mpa, tensile strength at yield >=12Mpa, tensile yield >=299.
High temperature resistant test: 125 ° of C*164h, outward appearance without distortion, contraction, crackle, be clamminess and separate out phenomenon.
