A polyester lining cloth

Abstract

This invention discloses a polyester padding fabric, comprising polyester fibers woven into a plain weave to form a plain fabric, which primarily serves a wear-resistant function; a pre-impregnated adhesive made of liquid epoxy resin, which permeates the plain fabric and bonds it into a whole, with the epoxy resin acting as a binder; and glass fibers in filament form wound around the outer surface of the plain fabric, bonded and fixed to it by the pre-impregnated adhesive, primarily increasing the load-bearing capacity of the padding fabric. By bonding and fixing it to the surface of the working parts, the surface of the parts can also possess good wear resistance, oxidation resistance, and corrosion resistance, thereby reducing wear, oxidation, and corrosion on the working surface of the parts and improving their service life.

Description

Technical Field

[0001] This invention relates to the field of wear-resistant materials, specifically a polyester padding cloth. Background Art

[0002] When sliding friction occurs between the two surfaces of a part, the friction will cause wear between the friction surfaces. As the amount of wear increases, friction damage or even failure will occur on the working surfaces. Moreover, due to the friction and the influence of surrounding environmental factors, oxidation and corrosion will occur on the friction surfaces of the parts, further damaging the contact surfaces of the parts.

[0003] For two surfaces with sliding friction, friction can cause frictional damage, oxidation, and corrosion between the working surfaces, thereby damaging the working surfaces or even causing them to fail. Existing wear-resistant materials act directly on the contact surfaces of the parts to delay the damage caused by friction. Most existing wear-resistant materials are resin injection molded sheets. In actual use, fixing them to the surface of the parts can only achieve isolation and wear prevention. However, under high pressure, the hard material is subjected to a large downward pressure, resulting in a large horizontal tensile force and vertical cracking, which affects normal use. In view of this, we propose a polyester padding cloth. Summary of the Invention

[0004] The purpose of this invention is to provide a polyester padding fabric to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A polyester padding fabric includes polyester, which is filamentous and woven into a plain weave to obtain a plain weave fabric. The polyester plain weave fabric mainly serves as a wear-resistant padding fabric.

[0007] Prepreg is made of liquid epoxy resin. The prepreg penetrates the plain weave fabric and bonds it into a whole. Epoxy resin is mainly used as a binder in the prepreg.

[0008] Glass fiber, which is filamentous, is wound around the outer surface of plain weave fabric. The glass fiber is bonded and fixed to the plain weave fabric with pre-impregnated adhesive. In padding fabric, glass fiber mainly plays the role of increasing load-bearing capacity.

[0009] As a preferred technical solution: a polyester padding fabric, the specific production steps are as follows:

[0010] S1. The raw material of polyester plain weave fabric is polyester. It is made by using a loom with an up-and-down weaving method to obtain polyester plain weave fabric with a plain weave texture.

[0011] S2. Polyester plain weave fabric is pre-impregnated using a pre-impregnating adhesive, which is epoxy resin.

[0012] S3. Roll the pre-impregnated polyester plain weave fabric onto the surface of a specific mold.

[0013] S4. Use a winding machine to wind glass fiber onto the surface of the prepreg fabric;

[0014] S5. Place the mold and the wrapped prepreg in an oven for heating, then allow it to cool and cure naturally.

[0015] S6. Demold using a demolding machine;

[0016] S7. Process the padding fabric to the designed dimensions.

[0017] As a preferred technical solution, E51 epoxy resin is used.

[0018] As a preferred technical solution, the glass fiber winding method is wet winding.

[0019] As a preferred technical solution, medium-alkali glass fiber is used.

[0020] As a preferred technical solution, the prepreg fabric is kept warm in an oven at 120°C for 4-5 hours.

[0021] 1. The lining fabric manufactured using this method, a plain polyester fabric, has good abrasion resistance. As an inner lining, it enhances the overall integrity and increases the load-bearing and compressive strength. By layering and reinforcing the plain polyester fabric with glass fiber, the tensile strength and resistance to breakage are further improved. The epoxy-impregnated plain polyester fabric, which is not in direct contact with air after being impregnated with epoxy resin, has good oxidation and corrosion resistance. After being bonded and fixed to the surface of the working parts, the surface of the parts can also have good abrasion resistance, oxidation resistance, and corrosion resistance, thereby reducing the wear, oxidation, and corrosion on the working surface of the parts and thus improving the service life of the parts. Detailed Implementation

[0022] Example 1: This example provides a polyester padding fabric. The main materials for manufacturing the padding fabric are plain polyester fabric and prepreg.

[0023] The functions of each component are as follows:

[0024] Prepreg: Primarily used as an adhesive;

[0025] Polyester: It mainly plays a role in abrasion resistance in padding fabric.

[0026] The core of this embodiment is to improve the integrity of the wear-resistant material. This is achieved by making specific improvements to the configuration and bonding method of the prepreg and polyester to prevent breakage under pressure from both top and bottom.

[0027] Regarding polyester, polyester is in the form of filaments, which are woven into a plain weave to obtain plain fabric. Polyester plain fabric mainly plays a role in abrasion resistance in padding fabric.

[0028] Regarding the prepreg, the prepreg is made of liquid epoxy resin. The prepreg penetrates the plain weave fabric and bonds it into a whole. The epoxy resin, as the prepreg, mainly acts as a binder. After the prepreg is fixed, the polyester plain weave fabric can be made into a fixed sheet.

[0029] The cured polyester plain weave fabric is directly fixed to the contact surface of the part. The epoxy resin can reduce the amount of wear between the contact surfaces. After the epoxy resin on the surface of the polyester plain weave fabric wears off, the polyester plain weave fabric comes into contact with the wear-resistant material again. The epoxy resin completely fills the gaps in the polyester plain weave fabric itself. The surface of the polyester plain weave fabric has good flatness, and the polyester plain weave fabric makes the padding fabric strong in integrity, with good tear resistance under pressure, which can prevent breakage and reduce friction damage, oxidation and corrosion damage on the surface of the part, thus protecting the working surface of the part and improving the service life of the part.

[0030] Example 2: This example provides a polyester padding fabric, the main materials of which are polyester plain weave fabric, prepreg and epoxy resin.

[0031] Regarding glass fiber, it is in the form of filaments and is wound around the outer surface of plain weave fabric. The glass fiber is bonded and fixed to the plain weave fabric by pre-impregnation. In padding fabric, glass fiber mainly plays the role of increasing load-bearing capacity.

[0032] For specific configurations of glass fibers, the following effects can be achieved:

[0033] 1. Fiberglass is in the form of filaments and can be adhered to the bottom of polyester plain weave fabric. The top of polyester plain weave fabric is connected to the parts. The fiberglass is arranged towards the sliding end. Due to the high strength of fiberglass, it is not easy to break under pressure and can play a role in increasing the load-bearing capacity in the padding fabric.

[0034] 2. The high strength and wear resistance of glass fiber can increase the wear resistance of the padding cloth.

[0035] In this embodiment, apart from the addition of glass fiber, the polyester plain weave fabric and prepreg involved are completely identical in structure to those in Example 1. For ease of understanding, part of the content of Example 1 is copied below:

[0036] Regarding polyester, polyester is in the form of filaments, which are woven into a plain weave to obtain plain fabric. Polyester plain fabric mainly plays a role in abrasion resistance in padding fabric.

[0037] Regarding the prepreg, the prepreg is made of liquid epoxy resin. The prepreg penetrates the plain weave fabric and bonds it into a whole. The epoxy resin, as the prepreg, mainly acts as a binder. After the prepreg is fixed, the polyester plain weave fabric can be made into a fixed sheet.

[0038] The cured polyester plain weave fabric is directly fixed to the contact surface of the parts, which can reduce the amount of wear between the contact surfaces. It also has very good oxidation resistance and corrosion resistance, which can reduce friction damage, oxidation and corrosion damage on the surface of the parts, thus protecting the working surface of the parts and improving the service life of the parts.

[0039] The lining cloth with added glass fiber has good wear resistance, oxidation resistance and corrosion resistance. After being bonded and fixed to the surface of the working parts, the surface of the parts can also have good wear resistance, oxidation resistance and corrosion resistance, thereby reducing the wear, oxidation and corrosion of the working surface of the parts and thus improving the service life of the parts.

[0040] The specific production steps are as follows:

[0041] S1. The raw material of polyester plain weave fabric is polyester. By using a loom to weave in an up-and-down manner, polyester plain weave fabric with a plain weave texture can be obtained.

[0042] S2. Polyester plain weave fabric is pre-impregnated with epoxy resin, and the pre-impregnating adhesive is epoxy resin (E51).

[0043] S3. Roll the pre-impregnated polyester plain weave fabric onto the surface of a specific mold.

[0044] S4. Use a winding machine to wind glass fiber (medium alkali glass fiber) onto the surface of the prepreg fabric. The winding method is wet winding.

[0045] S5. Place the mold and the wrapped prepreg in an oven and heat at 120℃ for 4-5 hours, then let it cool naturally and cure.

[0046] S6. Demolding is performed using a demolding machine. The prepreg fabric after demolding becomes a padding fabric with wear-resistant, oxidation-resistant, and corrosion-resistant functions.

[0047] S7. Process the padding fabric to the designed dimensions.
