Abstract
The invention relates to calcium carbonate fillers and particularly relates to a dimethyl silicone oil modified superfine heavy calcium carbonate filler for a coating. Modified calcium carbonate is prepared from following raw materials in parts by weight: 200 parts of superfine heavy calcium carbonate, 2-3 parts of dimethyl silicone oil, 1-2 parts of alginic acid, 2-3 parts of bauxite, 1-2 parts of vanadium boride, 2-3 parts of calcium laurate, 3-4 parts of glycerol triacetate and 4-5 parts of an auxiliary agent. The modified calcium carbonate powder is obtained by carrying out modification treatment on the superfine heavy calcium carbonate by adopting the raw materials including the dimethyl silicone oil, the alginic acid, the calcium laurate and the like, so that the modified calcium carbonate powder can be easily dispersed and dissolved in a base material; the raw materials including the bauxite, the vanadium boride and the like are added so that the fireproof flame retardant property of the powder is increased; the modified calcium carbonate filler can be used for effectively improving the indexes including the flexibility, impact strength, adhesive force, fireproof performance and the like and has wide application prospect.
Description
Technical field
The present invention relates to a kind of pearl filler, be specifically related to a kind of coating dimethyl silicone oil modified superfine heavy calcium carbonate filling and preparation method thereof.
Background technology
Calcium carbonate is the important functional inorganic filling of a class, have cheap, reserves are abundant, stable performance, easily processing, the advantage such as nontoxic, can improve significantly Drawing abillity, physicals and reducing production costs etc., be widely used in plastics, rubber, coating, the fields such as papermaking, because calcium carbonate is hydrophilic compounds, cause existing in actual applications and Polymers Phase capacitive deficiency, the defects such as bad dispersibility, can not reach satisfied filler reinforcement effect, therefore need calcium carbonate to carry out modification, to improve its dispersiveness and consistency in various types of materials, to reach effect of improving product performance.
Summary of the invention
The object of the invention is to, a kind of dimethyl silicone oil modified superfine heavy calcium carbonate filling is provided, to improve its surfactivity, make it in coating, have good dispersiveness and consistency, to achieve these goals, the technical solution used in the present invention is as follows:
Dimethyl silicone oil modified superfine heavy calcium carbonate filling for a kind of coating, it is characterized in that, this pearl filler is made up of the raw material of following weight part: superfine heavy calcium carbonate 200, dimethyl silicone oil 2-3, Lalgine 1-2, bauxitic clay 2-3, vanadium boride 1-2, calcium laurate 2-3, Vanay 3-4, auxiliary agent 4-5;
Described auxiliary agent is made up of the raw material of following weight part: Union carbide A-162 2-3, Zirconium tetrafluoride 1-2, nano silicon 1-2, linden ashes 1-2, linking agent TAC1-2, xitix 1-2; Its preparation method is that grinding distribution is even by each mixing of materials, to obtain final product.
Dimethyl silicone oil modified superfine heavy calcium carbonate filling for described a kind of coating, is characterized in that, described modified calcium carbonate is made by following method:
(1) first superfine heavy calcium carbonate is mixed with dimethyl silicone oil, Vanay, grind 15-20min, cross 150-200 mesh sieve;
