Abstract

The invention discloses an active calcium silicate, and a preparation method and application thereof. The preparation method comprises the following steps: (1) mixing a coupling agent and water to prepare a dispersion solution; (2) adding calcium silicate into the dispersion solution prepared in the step (1), and stirring; carrying out vacuum filtration to obtain modified active calcium silicate; and (3) drying the active calcium silicate prepared in the step (2). The invention also discloses a plastic stuffing which comprises the active calcium silicate, a lubricant, polymers and a compatilizer. The invention also discloses a method for preparing the plastic stuffing. When being used in blow molding, running, injection molding and other plastic products, the active calcium silicate or plastic stuffing has favorable dispersion effect and toughening effect.

Description

technical field [0001] The present invention relates to active calcium silicate, and further relates to a preparation method of active calcium silicate and its application in preparing plastic fillers, blow molding, tape casting, injection molding and other plastic products, and belongs to the technical field of preparation and application of active calcium silicate . Background technique [0002] Calcium silicate is a kind of plastic filler. Due to its low price, non-toxicity, and good chemical stability, adding it to plastics can reduce costs and improve the mechanical properties of products. Therefore, calcium silicate is used in plastics. Has a good application. Calcium silicate is an inorganic particle and has poor compatibility with plastics. Calcium silicate is directly added to plastics, which is prone to agglomeration and poor modification effect. At the same time, a large amount of dust and water vapor will be generated during processing, which is not conducive t...
