Embodiment 2

[0041] Material:

[0042] (1) The mass ratio of each component in the high-concentration sericite material is: 150 parts of sericite powder, 10 parts of resin acid, 20 parts of oxidized PE wax, 0.1 part of antioxidant 1010, and 30 parts of recycled HDPE, of which Resin acid is resin acid extracted from rosin, which is C 19 h 29 A mixture of organic carboxylic acids that are isomers of COOH. High concentration sericite material preparation method is the same as embodiment 1

[0043] (2) The mass ratio of each component of the hollow winding pipe is: 15 parts of high-concentration sericite material, 100 parts of recycled HDPE, and 0.2 part of black mother.

[0044] Preparation method of hollow wound pipe: same as in Example 1.

[0045] For the hollow wound pipe prepared in Example 2, performance tests such as ring stiffness were carried out according to GB / T14152-2004. Test results: see Table 1.

Embodiment 3

[0047] Material:

[0048] (1) The mass ratio of each component in the high-concentration sericite material is: 120 parts of sericite powder, 7 parts of resin acid, zinc stearate (industrial grade, produced by Jiangsu Nantong Huizhi Chemical Co., Ltd., the same below) 15 parts, 0.06 parts of antioxidant 1010, and 30 parts of recovered HDPE.

Abstract

The invention discloses a method for preparing high concentration sericite master batch and an application thereof. The high concentration sericite master batch includes 80-150 portions of sericite powder, 1-10 portions of resin acid, 5-20 portions of dispersant, 0.1-0.01 portions of antioxidant 1010 and 10-30 portions of recycled HDPE (high-density polyethylene). Sericite power is added to the high-speed mixer and heated to 105-110 DEG C. After 10 minutes of preheating, resin acid and antioxidant 1010 are added and mixed in high speed for 5-10 minutes. Then the oxidized PE wax and recycled HDPE are added. 10-30 minutes of mixing is needed before discharging. Mixture is fed in the twin-screw extruder for prilling to obtain sericite master batch and then produce the hollow winding pipe. The method significantly improves the rigidity of the recycled HDPE and also improves the ring rigidity of the prepared hollow winding pipe. Meanwhile, the prepared sericite master batch can be mixed with the recycled HDPE conveniently to produce the hollow winding pipe directly, thereby saving both production cost and energy.

Description

technical field [0001] The invention relates to a master material of sericite powder with reinforcing effect, in particular to a high-concentration sericite material and its preparation and application, which utilizes the flaky anisotropic characteristics of mica to strengthen and recycle HDPE to produce low-cost and high-strength Large-diameter hollow winding pipes are used for urban drainage. Background technique [0002] Plastic products have been widely used in all fields including industrial and agricultural production, construction, municipal construction, national defense construction, transportation, energy transmission, packaging industry, daily life, etc., and our country has discarded more than 3 million tons of plastic every year. Degradation in a short period of time has caused great pressure on my country's ecological environment. Recycling and reusing waste plastics has huge economic and social benefits. The development of the waste plastics recycling industry...
