Abstract
The invention discloses modified calcium carbonate with a flame-retardant effect. The modified calcium carbonate is characterized by being prepared from the following raw materials in parts by weight: 90-95 parts of calcium carbonate, 3-5 parts of carbide slag powder, 3-4 parts of vermiculite powder, 2-4 parts of antimonous oxide, 1-2 parts of asbestos fibers, 2-3 parts of zinc borate, 2-4 parts of ground nutshells, 6-8 parts of iso-octyl acrylate, 5-7 parts of acetyl citrate, 3-5 parts of EVA (ethylene vinyl acetate) wax, 1-2 parts of bromobisphenol a and 3-4 parts of modified titanium dioxide. According to modified calcium carbonate, flame-retardant components such as antimonous oxide and zinc borate are added for coating, and modified titanium dioxide is added after grinding, so that the dispersity is good and the cost increment due to raw material waste cannot be caused; fillers are used for producing assistants such as coatings, pigments and rubber.
Description
Technical field
The present invention relates to industrial filler field, particularly a kind of modified calcium carbonate with flame retardant effect 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.
