Problems solved by technology

Due to the complex manufacturing process and high cost of white carbon black, the current market price is 4,000 to 15,000 yuan / ton per share, which is unacceptable to users, and they are often replaced by mineral fillers with poor performance, resulting in damage to rubber and plastic products. low quality
In addition, there is a serious problem of environmental pollution in the manufacturing process of white carbon black.

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 1 Shown is the process flow chart of the cross-linking modification method of the glassy acidic lava micropowder provided by the embodiment of the present invention. The cross-linking modification method of the vitreous acidic lava micropowder provided by the invention comprises the following processes:

[0026] Raw materials: Vitreous acidic lava (commonly turpentine, obsidian, perlite, etc.), widely distributed in my country, with large reserves, often exposed to the surface, easy to mine, the price of raw ore is only 100-200 yuan / ton.

[0027] Crushing and pretreatment of raw materials: including coarse crushing and ultrafine crushing; rocks are heated to 500-600°C after coarse crushing and before ultrafine crushing, and rapidly cooled to below 100°C. Its purpose is twofold: one is to remove the adsorbed water in the...

Abstract

The invention provides a crosslinking modification method and a composite material of vitric acidic lava micro powder. By the method, a novel vitric acidic lava / difunctional silane coupling agent composite material can be prepared from natural rocks and can be applied to reinforcing agents and reinforcing fillers of rubber and the like. With low price, the composite material can replace reinforcing agents and reinforcing fillers of white carbon black, and other rubber and plastics; in addition, the production process of the composite material has no environment pollution.

Description

technical field [0001] The invention relates to the field of chemical product production, in particular to a method for organic crosslinking modification of vitreous acidic lava micropowder, and a novel vitreous acidic lava / bifunctional sulfur-silane coupling composite material produced by the method , mainly used as reinforcing agent and reinforcing filler for rubber etc. Background technique [0002] Natural rubber and synthetic rubber are the main materials of rubber technology, but their own strength is very low, and their mechanical properties are very poor. Adding reinforcing agent to raw rubber can significantly improve the mechanical properties of vulcanized rubber, making it an elastic material with a wide range of uses. The largest and most common reinforcing agents are carbon black and white carbon black. [0003] The rubber industry also uses a large number of non-metallic mineral materials as fillers (fillers), which account for about 1 / 4 of the rubber consump...
