According to calcium carbonate disclosed by the invention, waste hemp ropes, coal ash, waste cloth pieces and the like are secondarily used and a macromolecular polymer is added for coating; therefore, calcium carbonate not only has good mechanical property, but also is safe, environment-friendly and energy-saving and consumption-reducing. Moreover, in the production process, modified titanium dioxide is added after wet-process grinding, so that waste of raw materials is avoided. The multifunctional environment-friendly modified calcium carbonate disclosed by the invention is suitable for producing auxiliaries such as plastic, coatings and rubber.
Description
Technical field
The present invention relates to industrial filler field, particularly a kind of multi-functional environment-protection modified calcium carbonate and preparation method thereof.
Background technology
Calcium carbonate is a kind of very important functional inorganic filling, is widely used in the industrial circles such as plastics, rubber, coating and papermaking.In the Application Areas of calcium carbonate, most products belongs to the category of polymkeric substance, such as plastics, rubber, tackiness agent, coating etc., and occupies the important market share.The performance and application of properties-correcting agent to nano-calcium carbonate serves vital role.Such as, dispersion agent add the reunion that can reduce nano particle, improve dispersed; Adding of surface-modifying agent can improve the consistency of nano-calcium carbonate in polymeric system.As can be seen here, dispersion agent and surface-modifying agent are vital for the application of nano-calcium carbonate.But, adding of dispersion agent and surface-modifying agent, make nano-calcium carbonate temperature use window greatly to diminish, reason is that conventional dispersion agent and coupling agent are at high temperature easy to decompose, cause bubble, cracking, defect, distortion etc., thus affect the outward appearance of material, resistance toheat and mechanical property.Change the performance of traditional calcium carbonate product, improving its application performance to meet the needs of novel material, development of new techniques, is calcium carbonate industry urgent problem.
