Abstract
The invention discloses a surface-treated modified calcium carbonate. The invention is characterized in that the surface-treated modified calcium carbonate is prepared from the following raw materials in parts by weight: 85-90 parts of calcium carbonate, 1-2 parts of glyceryl tristearate, 1.5-2.5 parts of polyaspartic acid, 3-5 parts of rosin resin, 4-6 parts of nylon 66, 1-1.5 parts of palmitic acid, 2-3 parts of pulverized monkey grass, 2-3 parts of mullite, 1-2 parts of hydroxypropyl cellulose, 0.8-1 part of titanate coupling agent TC-WT and 2.5-3.5 parts of modified titanium dioxide. The calcium carbonate surface is modified by the high-molecular polymer, so that the calcium carbonate has the high-molecular polymer layer; the calcium carbonate has many active groups, and thus, has favorable compatibility with many substances. For example, the unsaturated double bond can generate crosslinking reaction with the film-forming matters in the rubber, plastic and paint to generate very strong binding force, and the use of abundant calcium carbonate as the filler can not lower the properties of the product.

In order to realize object of the present invention, the present invention passes through following scheme implementation:
A kind of surface treated modified calcium carbonate, is made up of the raw material of following weight part: calcium carbonate 85-90, Tristearoylglycerol 1-2, poly aspartic acid 1.5-2.5, Gum Rosin 3-5, nylon 664-6, palmitinic acid 1-1.5, pulverizing monkey grass 2-3, mullite 2-3, hydroxypropylcellulose 1-2, titanate coupling agent TC-WT0.8-1, modifying titanium dioxide 2.5-3.5;
Described modifying titanium dioxide is made up of the raw material of following weight part: nano titanium oxide 50-60, mica powder 2-4, pulverizing zeolite molecular sieve 4-6, ferrocene 5-7, mineral fibre 3-4, trisodium phosphate 2-3, pure-acrylic emulsion 3-4, epoxyoleic acid butyl ester 3-5, phosphoric acid ester 2-4, water 50-60; First preparation method adds pure-acrylic emulsion, nano titanium oxide, mica powder, pulverizing zeolite molecular sieve, mineral fibre, water to stir, form suspension, then add immediately ferrocene, epoxyoleic acid butyl ester, be heated to 120-140 DEG C, mix and blend 25-35 minute, is cooled to room temperature, then add all the other remaining components, under 1200-1500 rev/min of condition, stir, at 60-70 DEG C, dry, be ground into ultrafine powder and get final product.
The surface treated modified calcium carbonate of one of the present invention, made by following concrete steps:
(1) calcium carbonate, pulverizing monkey grass, mullite, hydroxypropylcellulose, titanate coupling agent TC-WT are mixed and added in shredder, grind 15-20 minute with the speed of 1500-2000 rev/min, take out and dry, pulverize porphyrize, cross 100-200 mesh sieve, obtain mixed powder stand-by;
(2) Gum Rosin, nylon 66, palmitinic acid are put into mixing tank, be warming up between 80-90 DEG C, mix and blend half an hour, continue to add Tristearoylglycerol, poly aspartic acid, continue to be warming up to 130-160 DEG C, mix and pour out after 15-20 minute, obtain material modified;
(3) mixed powder is mixed with material modified, add suitable quantity of water, stir and grind 2-3 hour, form suspension stand-by;
(4) suspension is mixed with modifying titanium dioxide, stir 10-15 minute under 800-1000 rev/min, dry, be ground into 200-400 order powder and get final product.
The invention has the beneficial effects as follows: the present invention's high molecular polymer is to calcium carbonate modifying surface, make calcium carbonate there is high polymer layer, owing to thering are a lot of active groups, therefore better with the consistency of many materials, such as the unsaturated double-bond containing can with rubber, plastics, coating in filmogen generation crosslinking reaction, produce very strong bonding force, also can not reduce in a large number the performance of product as their filler.
