preparation example Construction

[0015] The invention provides a method for preparing a high-hardness plastic manipulator, wherein the preparation method includes:

[0016] 1) mixing glass fibers with a silane coupling agent to obtain modified glass fibers;

[0017] 2) mixing and melting the polyamide plastic, the modified glass fiber prepared in step 1), wollastonite fiber, mica powder and lubricant to prepare the mixture M1;

[0018] 3) extruding and granulating the mixture M1 to obtain granules;

[0019] 4) After melting the granules obtained in step 3), the plastic manipulator with high hardness is obtained after being injected and filled into a mold, pressure-holding and shaped, and cooled and formed.

[0020] In the present invention, the glass fiber is modified with a silane coupling agent to change its physical and chemical properties such as specific surface area, and then polyamide plastic, modified glass fiber, wollastonite fiber, mica powder and lubricant are mixed and melted , then extrude the ...

Embodiment 1

[0033] 1) 100 parts by weight of glass fibers and 0.5 parts by weight of a silane coupling agent were mixed for 20 minutes at a temperature of 80° C. to prepare modified glass fibers;

[0034] 2) Put 100 parts by weight of polyamide plastics, 30 parts by weight of modified glass fiber prepared in step 1), 10 parts by weight of wollastonite fiber, 5 parts by weight of mica powder and 2 parts by weight of lubricant at a temperature of 260 Mixing and melting under the condition of ℃ to prepare the mixture M1;

[0035] 3) The mixture M1 is extruded and granulated by a twin-screw extruder with a screw speed of 300r / min (wherein, the temperature of the extrusion die is 190°C) to obtain granules;

[0036] 4) After melting the granules obtained in step 3), the high-hardness plastic manipulator A1 is obtained after injection filling into the mold (injection pressure is 140 Bar), pressure-holding molding (holding pressure is 100 Bar) and air-cooling molding .

Embodiment 2

[0038] 1) Mix 100 parts by weight of glass fiber with 2 parts by weight of a silane coupling agent at a temperature of 90°C for 30 minutes to prepare modified glass fiber;

[0039] 2) 100 parts by weight of polyamide plastics, 40 parts by weight of modified glass fiber prepared in step 1), 20 parts by weight of wollastonite fiber, 20 parts by weight of mica powder and 10 parts by weight of lubricant placed at a temperature of 300 Mixing and melting under the condition of ℃ to prepare the mixture M1;

[0040] 3) The mixture M1 is extruded and granulated by a twin-screw extruder with a screw speed of 330r / min (wherein, the temperature of the extrusion die is 230°C) to obtain granules;

[0041] 4) After melting the granules obtained in step 3), the high-hardness plastic manipulator A2 is obtained after injection filling into the mold (injection pressure is 160 Bar), pressure-holding molding (holding pressure is 120 Bar) and air-cooling molding .

Abstract

The invention discloses a high hardness plastic mechanical arm and a preparation method thereof. The preparation method comprises following steps: (1) mixing glass fibers with a silane coupling agentto obtain modified glass fibers; (2) mixing polyamide plastic, modified glass fibers, wollastonite fibers, mica powder, and a lubricating agent, and smelting the mixture to obtain a mixture (M1); (3)extruding and granulating the mixture (M1) to obtain particles; and (4) fusing the particles, injecting the fused particles into a mould, carrying out shaping under a constant pressure, and cooling and moulding to obtain the high hardness plastic mechanical arm. The glass fibers are modified by a silane coupling agent; then polyamide plastic, modified glass fibers, wollastonite fibers, mica powder, and a lubricating agent are mixed and smelted; then the mixture is extruded, granulated, and fused; and then the mixture is injected into a mould, shaped under a constant pressure, cooled, and moulded. The obtained mechanical arm has higher hardness and can meet the use requirements.

Description

technical field [0001] The invention relates to the field of plastic manipulator materials, in particular to a high-hardness plastic manipulator and a preparation method thereof. Background technique [0002] Plastics are widely used due to their good performance and renewable properties. Not only do we not come into contact with plastic materials all the time in our daily life, but even many equipment in the production industry are gradually using plastic materials instead of metal and other materials. As plastics are used more and more widely, for example, they are often used in engineering to make manipulators, etc., and the requirements for their hardness are also getting higher and higher. [0003] Therefore, it is an urgent problem to be solved by the present invention to provide a high-hardness plastic manipulator and its preparation method which has higher hardness and can meet the needs of engineering as a manipulator. Contents of the invention [0004] In view o...
