Problems solved by technology

[0003] At present, the pressure rollers on the glass fiber drawing machines at home and abroad are generally made of metal materials, but the wear resistance of this pressure roller is poor. Obvious nicks and uneven surfaces in contact with the yarn lead to poor product appearance and quality problems such as yarn fuzz. In addition, because the pressure roller is prone to wear and tear, it is necessary to replace the pressure roller frequently. On the one hand, it increases the Reduce the consumption of the pressure roller, increase the production cost of the enterprise, on the other hand, every time the pressure roller is replaced, it needs to be shut down, which reduces the work efficiency of glass fiber production and brings losses to the enterprise

Embodiment 1

[0051] Mix 60 parts of polyphenylene sulfide resin (PPS), 30 parts of glass fiber (with a length of 4.5 mm), 8 parts of talc powder, 0.3 part of silicone powder, and 0.5 part of antioxidant 168, and then feed it into the screw material of the injection molding machine The warehouse is melted and injected at 320°C to obtain the wear-resistant pressing roller blank; then through grinding, the smoothness of the workpiece can reach 0.4um, the straightness can reach 0.2mm / m, and the roundness can reach 0.02mm; The end processing is used to install the card slot of the pressure roller, which is made figure 1 Wear-resistant pressure rollers shown in .

[0052] Such as figure 1 The wear-resistant pressure roller 1 shown has a length of 280mm, a density of 1.6g / cm, and a hardness of HRL125. Both ends of the wear-resistant pressure roller 1 are provided with slots 110. Through the grooves 110, the wear-resistant pressure roller can be easily installed on the wire drawing on board.

Embodiment 2

[0054] Mix 80 parts of polyether ether ketone resin (PEEK), 10 parts of glass fiber (length range is 8mm), 8 parts of polytetrafluoroethylene micropowder, 0.3 part of TAF lubricant, 0.5 part of antioxidant 1010; mix the above raw materials from the feeding Put it into the screw silo of the injection molding machine, melt injection molding at 380°C, and obtain the wear-resistant pressing roller rough parts; and then grind the parts to achieve a smoothness of 0.38um, a straightness of 0.28mm / m, and a roundness of 0.03mm; At the end of the pressure roller, the installation hole 120 for installing the pressure roller is drilled to the inside of the pressure roller, and made as figure 2 For the wear-resistant pressing roller shown, the obtained wear-resistant pressing roller has a length of 280 mm, a density of 1.21 g / cm, and a hardness of HRL100.

Embodiment 3

[0056] 68 parts of polyether ether ketone resin (PEEK), 23 parts of carbon fiber (length range of 6mm), 5 parts of polytetrafluoroethylene micropowder, 3 parts of talcum powder, 0.2 parts of silicone powder, 0.3 parts of TAF lubricant, 0.5 parts of anti- The oxidant 1010 is mixed evenly, and the above-mentioned raw materials are fed into the screw hopper of the extruder, and melted and extruded at 380°C to obtain a wear-resistant pressing roller blank; through grinding, the wear-resistant pressing roller blank is ground until the smoothness reaches 0.35 um, the straightness reaches 0.23mm / m, and the roundness reaches 0.03mm; then a connection hole 130 is drilled in one section of the wear-resistant pressure roller 1, and a connection bolt 131 is cut and processed at the other end to make it as image 3 The wear-resistant pressure roller 1 shown, the length of the obtained wear-resistant pressure roller is 975mm, the density is 1.39g / cm, and the hardness is HRL115.

Abstract

The invention relates to a wear-resistant material for the compression roller of the glass fiber drawing machine, a resin matrix is adopted, fibers are added to serve as a reinforcing material, a certain wear-resistant modifier is added, a lubricating agent and an antioxidant are matched in a certain proportion, and on the basis that the strength is met, the self-lubricating property, the wear-resistant property and the stability are remarkably enhanced; and very low frictional wear in the long-term use process is ensured. The invention further provides a wear-resistant compression roller prepared from the wear-resistant material and used for a glass fiber drawing machine, the service life of the wear-resistant compression roller can be greatly prolonged, replacement is reduced, meanwhile,the appearance quality of glass fibers is improved, and the number of broken filaments and hairiness is reduced.

Description

technical field [0001] The invention relates to the technical field of glass fiber drawing, in particular to a wear-resistant material for a press roller of a glass fiber drawing machine, a wear-resistant press roller prepared from the wear-resistant material, and a preparation process. Background technique [0002] The wire drawing machine is a glass fiber drawing and forming winding equipment. When the glass fiber yarn is rolled into the wire drawing machine equipment, it needs to go through reciprocating motion to arrange the wire, and then feed the yarn ball after moving back and forth on the surface of the pressing roller. The role of group forming. [0003] At present, the pressure rollers on the glass fiber drawing machines at home and abroad are generally made of metal materials, but the wear resistance of this pressure roller is poor. Obvious nicks and uneven surfaces in contact with the yarn lead to poor product appearance and quality problems such as yarn fuzz. I...
