Example Embodiment

[0016] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the protection scope of the present invention. Improvements and adjustments made by technical personnel according to the present invention in practical applications still belong to the protection scope of the present invention. Example 1

[0017] (1) Prepare the following components in weight ratio: 55 parts of continuous alkali-free glass fiber and 45 parts of polytrimethylene carbonate;

[0018] (2) To process the continuous alkali-free glass fiber, first perform tension adjustment and static elimination treatment, and then perform preheating. The preheating temperature is 120°C, and then perform another tension adjustment; melt the polytrimethylene carbonate;

[0019] (3) Dip 55 parts of continuous alkali-free glass fiber treated in step (2) into 45 parts of melted ...

Abstract

The invention provides a preparation method of a resin material, the resin material is used for mold manufacturing, comprising: (1) preparing the following components by weight ratio: 50-55 parts of glass fiber, 45-50 parts of thermoplastic resin; (2 ) to process the glass fiber, first perform tension adjustment and static removal treatment, then preheat, and then perform another tension adjustment; melt the thermoplastic resin; (3) 50~55 parts of glass fiber treated in step (2) Impregnate into 45~50 parts of melted thermoplastic resin, impregnate the glass fiber and introduce it into the impregnated calender roll group for roll forming to make it completely impregnated. (4) cutting the ribbon-shaped fiber prepreg obtained in step (3), then hot-pressing, and then performing cold-pressing treatment to become a plate-shaped material, which can be used in molds. Manufactured resin material.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of resin materials. Background technique [0002] As an indispensable tooling for modern industrial production, molds play a decisive role in production. Most of the current molds are made of metal. The quality and life of metal molds are very high, but their production costs are expensive, especially for some complex shapes. The forming process of metal molds is extremely complicated, and many metal materials also have the defects of difficult processing, long processing cycle, and long repair time after the mold is worn. This makes the merchants who choose to use it do not have a favorable opportunity in time in the competition, and its higher cost makes the profit decline. [0003] With the rapid development of industry, the strength and precision of polymer composite materials are continuously improved, and the application range of ...
