Problems solved by technology

Because it adds acrylamide that can be dissolved in water for fishing supplies, the modified resin can be decomposed in water to avoid environmental pollution. There is basically no application value in communication equipment, medical equipment, toys, sports and leisure equipment, and there are still unreasonable things in its technology, so that its performance cannot meet people's basic needs

Embodiment Construction

[0023] Below in conjunction with embodiment the present invention is described in further detail.

[0024] Implementation Example 1

[0025] A kind of production method of high specific gravity resin is characterized in that the steps are as follows:

[0026] (1) Surface activation pretreatment of tungsten powder Mix tungsten powder and surfactant in a ball mill at room temperature in a ratio of 1000:0.8, and the specific gravity of tungsten powder is 19.1-19.5 g / cm 3 , the fineness is in the range of 200-300 mesh, and the surfactant adopts the composite active agent of the SA-HDR brand produced by Ningbo Nengzhiguang New Material Technology Co., Ltd. It adopts silane KH550: adipic acid: stearamide is 3.5- 4.5: 2.5-3.5: 2.5-3.5, and dissolve and dilute with 15-25 parts of ethanol, and their optimal ratio is 4:3:3 of silane KH550: adipic acid: stearamide, and dissolve and dilute with 20 parts of ethanol.

[0027] (2) Stir and mix at high speed, stir nylon PA powder, coupling ...

Abstract

Production of high-specific weight is carried out by mixing tungsten powder with surface activator in proportion of 1000:0.8-1.5 proportion, agitating at normal temperature in ball grinder, surface activation pre-treating, mixing Nylon PA powder and coupler with plasticizer, lubricant, brightener and anti-ageing agent in proportion of 18-22:0.3-0.5:0.8-1.2:1.1-1.5:0.1-0.3:0.08-0.12 proportion, high-speed agitating in agitator at 600-900 circle / min for 6-10 mins, metering while charging for Nylon PA powder and accessory in bi-screw extruder, passing through paralleling streamline-shaped internal-cavity mouth, extruding into flake at 180-220 degree and 8-20 circle / min, and crushing to obtain final product. It's convenient and reasonable, and has excellent universal performance.

Description

technical field [0001] The invention relates to the technical field of a production method of a high specific gravity resin. The method uses a unique processing aid and a process formula, adopts improved special equipment, and can produce a high specific gravity resin with a specific gravity as high as 9-14, which can be used to replace harmful heavy metals . Background technique [0002] High specific gravity resin is a composite material developed in response to the impact of harmful metals on the environment in recent years, which can replace metal lead and other harmful metals. It uses thermoplastic resin as the base material, and adds high specific gravity metal powder as filler. Through different weight ratios Combined with materials, a series of engineering plastics with specific gravity above 6 and unique performance and applicability can be obtained. [0003] Because its specific gravity is comparable to that of metal, high specific gravity resin can be used to rep...
