Abstract
The invention relates to an ultra-fine calcium carbonate modified and filled master batch preparation method, which uses the following raw materials (by weight), and comprises: (1) adding 100 parts of ultra-fine inorganic calcium carbonate powder into a high speed mixer, and carrying out stirring dehumidification; (2) adding 2-4 parts of a modifier to carry out organic modification on the ultra-fine inorganic calcium carbonate; (3) adding 9-15 parts of a granulation carrier and 3-4 parts of a lubricant, and uniformly mixing and stirring; and (4) adding to an extrusion granulator, and granulating to obtain the modified and filled master batch. According to the present invention, with the modification treatment on the ultra-fine heavy calcium carbonate, the inorganic calcium carbonate surface is changed into the organic calcium carbonate surface, the calcium carbonate agglomeration is prevented, the poor dispersion of the calcium carbonate powder during the filling process is significantly improved, the filling amount of the calcium carbonate powder in the plastic product is improved, and the plastic product cost is reduced; and the polypropylene filling master batch produced by using the method can be widely used in plastic woven products, extruded plastic tubes and pressure plastic products, and the addition amount of the directly-used inorganic calcium powder does not exceed 5% while the addition amount of the ultra-fine calcium carbonate modified and filled master batch produced by using the method is 10-40%.
Description
Technical field
The present invention relates to a kind of preparation method of calcium carbonate superfine powder modified filler masterbatch, the plastic filler carrying out modified production, for saving plastic raw materials, reduces plastics production cost, provides the type material of energy-conserving and environment-protective.
Background technology
Society, the main daily necessities of people mostly is plastics, and plastic raw materials mainly refines machining from oil obtains.Along with the development of economy, constantly riseing of crude oil price, plastic raw materials price is caused to rise to 13000-14000 yuan/ton by every 3000-4000 yuan/ton, and then the cost of plastics improves, for complying with economic situation, reduce the production cost of plastics manufacturing enterprise, it is inexorable trend that plastics adopt calcium carbonate-filled.
Being prepared in traditional technology of calcium carbonate superfine powder filling master batch directly adds inorganic calcium powder, has the effect reduced costs in this way.But there are three problems: (1) directly uses inorganic carbonate calcium, in production process, dust is large, causes work under bad environment; (2) inorganic powder filled amount is little, and the amplitude reduced costs is too small, does not reach predictive role; (3) directly filling causes frosting rough, and various performance index are unstable, cause product quality problem to take place frequently.
Summary of the invention
The object of the invention is to for above-mentioned the deficiencies in the prior art, a kind of preparation method of calcium carbonate superfine powder modified filler masterbatch is provided, the method uses high-speed mixer that calcium carbonate superfine powder is carried out activation modification, and obtained modified filler masterbatch significantly can reduce the production cost of plastics.
The technical solution adopted in the present invention is: a kind of preparation method of calcium carbonate superfine powder modified filler masterbatch, adopts the raw material of following weight part, obtain according to the following steps:
(1) ultra-fine inorganic calcium carbonate powder 100 parts is added in high-speed mixer, stir dehumidifying;
(2) then add properties-correcting agent 2-4 part and organic decoration is carried out to ultra-fine inorganic calcium carbonate;
(3) then add the carrier 9-15 part needed for granulation, lubricant 3-4 part, be uniformly mixed;
(4) granulation of extrusion granulating machine is added, obtained modified filler masterbatch.
Described properties-correcting agent is stearic acid and titanate coupling agent; Described carrier is resin; Described lubricant is white oil or paraffin.
Described stearic acid and the mass ratio of titanate coupling agent are 2:3.
Described resin is polypropylene (Polypropylene is called for short PP).
Calcium carbonate superfine powder modified filler masterbatch prepared by the preparation method described in a kind of basis.
By the modification to superfine heavy calcium carbonate in the inventive method, calcium carbonate surface is organic by inorganic change, prevent the reunion of calcium carbonate, significantly improve the situation of calcium carbonate powder bad dispersibility in the filling process, improve the loading level of the calcium carbonate powder in plastics, reduce plastic prod cost.Adopt the polypropylene filling master batch that the inventive method is produced, plastic knitting, extruded pipe, moulded item can be widely used in, as refrigerator, air conditioner housing, bumper etc., the inorganic calcium powder addition of direct use is no more than 5%, and the calcium carbonate modified filling master batch addition using the inventive method to produce is at 10%-40%.
