Embodiment Construction

[0052] Below in conjunction with specific example the present invention is described in further detail, the preparation method of a kind of 200 type polyester fiberglass dipped canvas (hereinafter represented by EG200 code name) among the present invention is as follows:

[0053] Preparation of warp and weft materials:

[0054] 1. Warp material: 1100dtex-3300dtex polyester industrial filament can be used. According to the variety requirements of customers, ordinary type, high-strength type, low-shrinkage type and high-modulus low-shrinkage type can be used for twisting production.

[0055] Type EG200 uses 1100dtex high-modulus low-shrinkage polyester industrial filament. According to the strength requirements of type 200, it needs to use 2 strands, that is, 1100dtex×2, and the twist range is 100±15 twists / m;

[0056] 2. Weft material: 150tex-2000tex modified glass fiber filaments. When spinning glass fiber, the following requirements are put forward. It is glass fiber of alk...

Abstract

The invention provides a polyester glass fiber dipped canvas and a preparation method thereof. Silk is woven into canvas. The single fiber diameter of glass fiber filaments in weft direction is ≤12μm. The glass fiber is a modified glass fiber filament, based on the total weight of the modified glass fiber filament, it consists of: SiO 2 : 50%~56%, Al 2 o 3 : 12%~16%, B 2 o 3 : 6%~9%, MgO: 2%~4%, CaO: 16%~20%, Na 2 O or / and K 2 O: 0.15% to 0.4%, Fe 2 o 3 : 0.1%~0.4%, TiO 2 or / and ZrO 2 : 0~0.1%, F 2 : 0.1% to 0.3%. The raw material cost is low, the preparation process is simple and reasonable, and the product has high heat resistance and dimensional stability.

Description

technical field [0001] The invention relates to a rubber conveyor belt frame material dipped canvas and a manufacturing process thereof, in particular to a polyester glass fiber dipped canvas and a preparation method thereof. Background technique [0002] With the rapid development of the world's industry, it has also brought about the shortage of resources. As the main energy source, oil is an important material that countries all over the world attach importance to. Nylon and polyester synthetic fibers are the end products of petroleum, and their prices are also relatively high. The main skeleton material used in the rubber conveyor belt industry is exactly the dipped canvas interwoven with nylon, polyester, and polyester-nylon. [0003] Existing nylon, polyester, and nylon dipped canvases are produced from industrial filaments through twisting, weaving, and dipping. They have the advantages of high strength and good flexibility, but they also have heat resistance and sta...
