The rubber industry is currently called more complex, the original rubber only refers to natural rubber or synthetic rubber, but there are also some elastomers called rubber. Rubber in modern industry because of its large pollution, many conventional rubber products have been gradually replaced, but many such as tires, conveyor belt and other rubber products, still have not found a suitable alternative products, rubber materials are widely used in automotive products, footwear, conveyor and other industries.

In recent years, due to the production of more fine-grade talc grinding equipment, talc powder has smoothly entered the application of water-based coating systems, and is currently used in a variety of priming, intermediate coating, road marking paint, industrial paint, as well as internal and external architectural coating, due to the soft texture of talc powder, good dispersion, suspension, in the coating industry filling material occupies a large proportion.

Adhesive is generally made of bonding material (matrix resin), curing agent, toughening agent, diluent and filler, etc. It is widely used in packaging, electronic and electrical appliances, building materials, automobiles and transportation, machinery manufacturing, new energy, medical health, aerospace and other fields.

The lamellar structure of talc makes certain properties of talc-filled plastics greatly improved, and talc is a reinforcing filler in plastics. First of all, talc can improve the stiffness of the filler material and creep resistance at high temperatures. When the talc particles are arranged along the direction of material flow during processing, according to the principle of least resistance, the arrangement is basically flaky, from small pieces of refining into large pieces. Thus, it can significantly improve the material stiffness in a specific direction. Secondly, talc can significantly improve the filler material heat resistance. Used to measure the heat resistance of the material heat distortion temperature refers to the specimen under a certain load bending to a certain degree of temperature, sheet talc in a specific direction to improve the thermal deformation temperature of the material.

As a filler used to reduce the cost of paint, which is based on the structure of talc powder and its own low cost.

Talc not only plays a role in reducing costs in plastic modification, but also has an obvious enhancement effect, but not all talc will have an enhancement effect. With the difference of product grade, the difference is very obvious. And the types of plastics are different, the performance is not the same, the processing equipment is different, it is difficult to give a unified specific standard for the talc used in the plastic industry. The overall principle of selecting talc powder in the plastics industry is: try to use talc powder products with matching particle size, talc raw materials and particle size distribution must be stable, and the distribution range should be narrow to ensure the stability of the quality of plastic products.

With the continuous expansion of the application field of nano-calcium carbonate, these shortcomings are more obvious. In order to give full play to the advantages of nano-calcium carbonate and improve the performance of nano-calcium carbonate, different surface modification methods and modifiers must be used for surface modification treatment.

Talc is a water-containing layered silicate mineral with the chemical formula 3MgO•4SiO2•H2O. Talc powder has good chemical stability, strong acid and alkali resistance, but also has good electrical insulation properties and heat resistance. As an excellent functional raw material and filler, it can be used in plastics. Modification can change the surface affinity of talc powder, so that plastic and talC better combination.

With the continuous improvement of society on mining, impurity removal and production processes, transparent inorganic fillers are now slowly entering the filler market, playing a significant role in coatings, modified plastics and other industries.
