Abstract
The present invention relates to a rubber reinforcing filler. Its formula is composed of (wt%) 99.2-99.5% of wollastonite and 0.5-0.8% of coupling agent silica 69. Its preparation process is as followsL: the wollastonite is pulverized to that its grain size is greater than or equal to 400 meshes, placed in reaction still, heated to 105-115 deg.C, the coupling agent silica 69 is added, stirred for 10-15 min., then discharged, weighed, packaged and put in storage. it features easily available raw material, low cost, uniform mixing, good dispersity, short period, low energy consumption and high production efficiency and has the advantages of good abrasion performance, light colour and no contamination, etc..
Description
The present invention relates to a kind of rubber filler, particularly a kind of white carbon black rubber reinforcing filler.
At present, in the weighting agent of rubber reinforcing filler, be strengthening agent how with the carbon black.Usually the black-reinforced agent that adds is better with carbon black N500, N600, the N700 trade mark of U.S. ASTM name, doses these strengthening agents and can reach and improve rubber item intensity, can increase tensile strength, hardness, abrasion performance and the anti-performance such as scratch of vulcanized rubber.But this strengthening agent costs an arm and a leg, and can bring operating environment to pollute.White carbon black is good rubber reinforcing filler, can reduce the rubber item cost significantly, can improve operating environment again.
The prescription and the method for making thereof that the purpose of this invention is to provide a kind of rubber reinforcing filler.
Technical scheme of the present invention is finished like this.
A kind of prescription of rubber reinforcing filler comprises:
Wollastonite: 99.2-99.5% (weight part)
Coupling agent silicon 69:0.5-0.8% (weight part)
Blending process is: the wollastonite processing powder is broken to 〉=400 purpose granularities, drops into when heating 105-115 ℃ in the reactor, add coupling agent silicon 69, stir discharging after 10-15 minute, weigh, pack warehouse-in.
Wollastonite rubber reinforcing filler of the present invention, raw material is easy to get, and cost is low, mixing evenly, be easy to disperse, the cycle is short, power consumption is little, boost productivity, easily manufactured, reduced investment.The principal feature that is formulated into cross-linked rubber is that tensile strength height, elongation are big, elasticity and good heat resistance, and the tearing toughness height has the effect of anti-old, reinforcement, filling to rubber item.The sizing material property endured is good in extrusion, compressing technology, dimensional stabilizing, and good fluidity improves the bonding force of glue and wiring.Also have characteristics wear-resisting, that fall low-heat-generation, advantage such as of light color, as not pollute.
