Problems solved by technology

[0003] However, the current PPS profiles in the market are basically based on a single extrusion molding process, but the physical properties of the profiles such as surface hardness and steel strength are relatively weak, which is limited in the application field of "replacing steel with plastic". , so it is necessary to produce plastic products with steel properties closer to metal materials

Embodiment 1

[0023] The present invention provides a kind of forming technology of high rigidity PPS sheet material, comprises the following steps:

[0024] (1) Dry the PPS granules in an oven at 140°C for 3 hours, then put them into the barrel of the extruder and use 80°C circulating hot air to continue drying until the moisture content of the PPS granules is 0.2%, and then mix with glass fiber , the weight percentage of the PPS particles is 40%, and the weight percentage of the glass fiber is 60%, to obtain a raw material blend;

[0025] (2) Introduce the raw material blend obtained in step (1) into the barrel, and set the temperature of the barrel in three stages along the extrusion direction of the raw material blend. The temperature of the first stage is 280°C, and the temperature of the second stage is 305°C. The temperature of the third stage is 320°C, and the screw is extruded at a speed of 20r / min, so that the fluid melt passes through the extrusion joint at 330°C and flows to the...

Abstract

The invention relates to a high-rigidity PPS plate and a forming process of the high-rigidity PPS plate. The forming process comprises the following steps that (1) PPS particles are dried and mixed with glass fibers to obtain a raw material blend; (2) the raw material blend obtained in the step (1) is made to pass through a machine barrel, and extruded to a high-temperature charging barrel through a screw rod to form a bubble-free primary blank; (3) the bubble-free primary blank obtained in the step (2) is placed into a die, and pressed and formed by a die press to obtain a primary plate; and (4) the primary plate obtained in the step (3) is annealed to obtain the high-rigidity PPS plate. According to the forming process, the problem of difficulty in forming simultaneously extruded glass fibers and PPS particles is effectively solved, the internal stress of the plate is eliminated, and the density, the rigidity and the surface hardness of the plate are improved; and in addition, the problem of air holes in the product is completely eliminated, and the structure and density of the product are better than those of a common PPS plate.

Description

technical field [0001] The invention belongs to the field of plates, and in particular relates to a high-rigidity PPS plate and a forming process thereof. Background technique [0002] Polyphenylene sulfide (PPS) plastic is a thermoplastic special engineering plastic with excellent comprehensive properties. Its outstanding features are high temperature resistance, corrosion resistance and good mechanical properties. [0003] However, the PPS profiles in the current market are basically based on a single extrusion molding process, but the physical properties of the profiles such as surface hardness and steel strength are relatively weak, which is limited in the application field of "replacing steel with plastic". , so it is necessary to produce plastic products whose rigidity is closer to that of metal. Contents of the invention [0004] In order to solve the problems in the prior art, the invention provides a high-rigidity PPS plate and its forming process. The forming p...
