Abstract
A composition as reinforcing agent for rubber is prepared through calcining diatomite powder, crushing, wind selection to obtain product of granularity less than 20 microns, addition of silane as coupling agent and high-speed stirring by adding white carbon black or carbon black, and features stable chemical properties, high termal stability and acid resistance and low cost. It serves to increase the mechanical performance of rubber.
Description
The invention belongs to Chemicals, relate to a kind of invention the rubber item strengthening agent.
At present, in rubber item, for the requirement that reaches required various physical strengths will be added strengthening agent, present used strengthening agent generally has two kinds, in the light-colour rubber goods, use white carbon black, use carbon black in the black rubber goods, these two kinds of strengthening agents exist and have certain weak point in price height, reinforcement difference and the course of processing.
The purpose of this invention is to provide the composite material rubber reinforcing agent that a kind of price is low, easy to manufacture, reinforcing property is good.
It is raw material that technical scheme of the present invention is selected the diatomite in powder dry product for use, its silicon-dioxide (SiO
2) content is greater than 85 percent, raw material is through selected back roasting, maturing temperature is at 400 ℃-900 ℃, time is 35 minutes to 1 hour, raw material after the roasting goes out particle diameter below 20 microns through pulverizing selection by winnowing, silane coupling agent with 20/2/1000ths to thousand joins particle diameter in diatomite powder below 20 microns, the diatomite powder that adds silane coupling agent is mixed (its proportioning is decided according to the needs of rubber item) with white carbon black or carbon black high-speed stirring, promptly make composite material rubber reinforcing agent.
Positively effect of the present invention is owing to adopt the diatomaceous strengthening agent that adds silane coupling agent, use every physical strength to be improved separately than white carbon black or carbon black, and reduced the compression set of rubber item, chemical property is stable, heat-resisting, acidproof, excellent propertys such as insulation, reduce the cost of rubber item, satisfied the particular requirement of a lot of rubber items.
Embodiments of the invention are:
Selecting the diatomite in powder dry product for use is raw material, raw material is put into the stoving oven roasting, the temperature of stoving oven is divided intake zone, the three kinds of temperature in intermediate zone and combustion zone, the intake zone temperature is about 400 ℃, the intermediate zone is 600 ℃, the combustion zone is about 850 ℃-900 ℃, raw material is put into intake zone and was got final product discharging in about 40 to 50 minutes to the combustion zone required time, raw material through naturally cooling after the roasting after pass through selection by winnowing after the powder essence again, the particle diameter of raw material is reached below 20 microns, in the diatomite powder below 20 microns, stir and get final product by weight 5/1000ths silane coupling agent being joined particle diameter then; Diatomite powder with 45% (containing silane coupling agent) and 55% white carbon black or carbon black stir, and promptly make composite material rubber reinforcing agent.
Claims (2)
1, a kind of composite material rubber reinforcing agent, it is characterized in that: selecting the diatomite in powder dry product for use is raw material, its dioxide-containing silica is greater than 85 percent, raw material is through selected back roasting, maturing temperature is at 400 ℃-900 ℃, time is 35 minutes to 1 hour, and the raw material after the roasting goes out particle diameter below 20 microns through pulverizing selection by winnowing, and the silane coupling agent with 20/2/1000ths to thousand joins particle diameter in diatomite powder below 20 microns.
2, composite material rubber reinforcing agent according to claim 1 is characterized in that: the diatomite powder that will add silane coupling agent mixes with white carbon black or carbon black high-speed stirring, and its proportioning is decided according to the needs of rubber item.
