CN103012943A - Method for preparing high-solute LDPE (Low-Density Polyethylene) powder dispersant color masterbatch - Google Patents

Abstract

The invention relates to a method for preparing a high-solute LDPE (Low-Density Polyethylene) powder dispersant color masterbatch, belonging to the field of chemical industry production technologies. The high-solute LDPE powder dispersant color masterbatch is made from the following raw materials in weight fraction: 30% of carrier, 40% of inorganic pigment, 15% of polyethylene wax and 15% of LDPE powder. According to the method for preparing the high-solute LDPE powder dispersant color masterbatch, the polyethylene wax is replaced with the 15% of LDPE powder, so that the effects of improving the coloration ability and apparent quality of the color masterbatch and reducing the cost of the color masterbatch are achieved; and meanwhile, the color masterbatch has good physical properties, and serves as a carrier and plays the role of a dispersant in a color masterbatch material, so that the market competitiveness of the color masterbatch is enhanced.

Description

High solute LDPE powder dispersing agent look mother's preparation method

Technical field

The present invention relates to a kind of high solute LDPE powder dispersing agent look mother's preparation method, belong to chemical production technical field.

Background technology

At present; look mother's Main Function is exactly in order to painted; like this along with the development of technology; existing look female effect is comparatively single; and in the look female process of using, often can require the look mother to possess again other effects, and for example in use namely need look mother's tinting strength, also need simultaneously it to possess some physicalies; under these require, present look mother just seem can not satisfying the market demand.

Summary of the invention

According to the deficiencies in the prior art, the technical problem to be solved in the present invention is: provide a kind of high solute LDPE powder dispersing agent look female, this look female, and Color is good, also possesses simultaneously good physicals; This preparation method of while, technique is simple, convenient operation.

The technical solution adopted for the present invention to solve the technical problems is: provide a kind of high solute LDPE powder dispersing agent look female, made by the raw material of following parts by weight:

Carrier 30 as one kind ﹪

Mineral dye 40%

Polyethylene wax 15%

LDPE powder 15%.

Described carrier is linear low density polyethylene (LDPE).

Described mineral dye is phthalocyanine green or phthalocyanine blue.

Described high solute LDPE powder dispersing agent look mother's preparation method is characterized in that following steps:

(1) LDPE is ground to form 3 microns powder with pulverizing mill;

(2) in proportion carrier, pigment and LDPE powder are dropped into high-speed mixer and be mixed to drying;

(3) polyethylene wax is added in proportion in the above-mentioned starting material with combination drying, again again stirs, until bonding evenly, emit and dry;

(4) will dry rear material and drop into granulation in the forcing machine, make product.

The invention has the beneficial effects as follows: the LDPE powder with 15% substitutes polyethylene wax, effect improved the look mother tinting strength and apparent mass, reduced cost, also possessed simultaneously good physicals, in colour batch, namely play the dispersion agent effect as carrier, strengthened the competitiveness of product in market.

Embodiment

Below in conjunction with embodiment the present invention is described further:
