Embodiment Construction

[0009] The processing process is as follows:

[0010] 1. Select raw material diatomite and its Slo 2 The content is more than 85%, and the algae species are preferably long. After natural drying, when the water content is 20%, it is crushed, sorted, and impurities are removed.

[0011] 2. Put the selected materials into a drying kiln for drying at a temperature of 200°C for 1 hour, so that the moisture content of the materials is below 5%. The kiln is a dynamic kiln, and the heat source can be selected from various methods such as fuel oil, gas, electric heating, etc. .

[0012] 3. After the material is dried and released from the oven, after crushing and winnowing, select the fine powder with a particle size below 20 μm, put it into the coating equipment, add a silane coupling agent, and use diatomaceous earth and coupling agent for coating. The agent is fully combined with the device. The amount of coupling agent added is 2‰-10‰ of the weight of diatomite. The model of ...

Abstract

The present invention, diatomite rubber reinforcing agent, relates to non-metal mineral product. The present invention features that diatomite is prepared into the diatomite rubber reinforcing agent to replace white carbon black. The rubber reinforcing agent with high quality and low cost is prepared with diatomite and through material selection, eliminating impurity, drying in kiln, crushing, wind selection and other technological processes.

Description

technical field [0001] The present invention relates to diatomite, a non-metallic mineral product. Background technique [0002] In rubber products, in order to achieve the various mechanical strengths required, functional inorganic filler reinforcing agents should be added. There are two types of reinforcing agents currently used: carbon black for black rubber and white carbon black for light-colored rubber. The product of the present invention is light-colored and mainly replaces white carbon black. The production of white carbon black requires complex processes such as water glass and hydrochloric acid to be made into acidic silica sol through chemical reaction, and then mixed with alkaline water glass to add regulator, heat and catalyze in the reaction kettle, so the cost is high and the price is high. Contents of the invention [0003] The object of the present invention is to provide a rubber reinforcing agent with simple manufacture, low price and excellent perfor...
