Embodiment Construction

[0011] A composite powder for rubber, which is made from the following raw materials in parts by weight (kg): calcium carbonate 70, diatomaceous earth 50, crosslinking agent TAC2, aluminum nitride 0.6, antimony trioxide 4, Antioxidant DLTP2, NDZ-401 titanate coupling agent 5, dimethyl phthalate 2, dioctyl adipate 0.7.

[0012] Described a kind of calcium carbonate composite powder for rubber, preparation method is:

[0013] (1) After calcining the diatomite at 500°C for 2 hours, take it out, cool it, and grind it into nano-powder to obtain nano-calcined diatomite for later use;

[0014] (2) After sintering calcium carbonate at 280°C for 1 hour, take it out and cool it down to obtain calcined calcium carbonate, which is ready for use;

[0015] (3) After mixing the other raw materials except diatomite and calcium carbonate by weight, add an appropriate amount of water and stir at 35°C for 20 minutes to obtain a modified solution. Finally, mix nano-calcined diatomite with calcin...

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 [0001] The invention relates to the field of rubber production, in particular to a composite powder for rubber. Background technique [0002] The fillers used in the existing rubber products mainly play a reinforcing role and increase the strength performance of the rubber. The existing rubber-filled electrodeless powder has a single type and a single function, which cannot meet the diversified needs. Contents of the invention [0003] The object of the present invention is to provide a composite powder for rubber that can simultaneously play the roles of flame retardancy, anti-aging and reinforcement. [0004] The above purpose is achieved through the following schemes: [0005] A composite powder for rubber, characterized in that: it is made from the following raw materials in parts by weight: calcium carbonate 60-70, diatomaceous earth 30-50, crosslinking agent TAC1.5-2, nitriding Aluminum 0.4-0.6, antimony trioxide 3-6, antioxidant DLTP1-2, NDZ-401 t...
