Dacron glass fiber dipped canvas and its preparation method

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...
