Problems solved by technology

The impregnation formula and cloth base design can not meet the application conditions of abrasive belts with high strength and softness at all, which will cause problems such as softness and insufficient strength, breakage, elongation, etc., and eventually cause the service life of the formed abrasive belt to decrease, and the softness is not suitable Workpiece environment

Embodiment 1

[0072] Use rayon as the raw material of the cloth base for weaving; perform surface treatment to remove the fluff on the surface of the cloth base; pass the cloth base through a stretching machine, with a warp stretch rate of 6% and a weft shrinkage rate of 8%. The warp strength of the cloth base is 1150N / 5cm; the weft strength is 450N / 5cm; the cloth base is impregnated through a dipping tank containing rubber; after impregnation, the cloth base is dried at 70°C and then set at a high temperature of 160°C; Including 10 parts by weight of modified resin; 70 parts by weight of emulsion; 0.1 part by weight of penetrant; the viscosity of the rubber material is 10CPS, and the pH value is 6; Dried under; Coating machine scratch coating used coating comprises modified resin 10 weight parts; Emulsion 70 weight parts; Filler 10 weight parts; Defoamer 0.1 weight part; Wetting agent 0.1 weight part; Pigment 1 weight part; It is 1000CPS, and the pH value is 8; the cloth base is calendered...

Embodiment 2

[0074] Use rayon as the raw material of the cloth base for weaving; perform surface treatment to remove the fluff on the surface of the cloth base; pass the cloth base through a stretching machine, with a warp stretch rate of 8% and a weft shrinkage rate of 10%. The warp strength of the cloth base is 1200N / 5cm; the weft strength is 480N / 5cm; the cloth base is impregnated through a dipping tank containing rubber; after impregnation, the cloth base is dried at 90°C and then set at a high temperature of 190°C; Including 10 parts by weight of modified resin; 70 parts by weight of emulsion; 0.1 part by weight of penetrant; the viscosity of the rubber material is 10CPS, and the pH value is 6; Dried under; Coating machine scratch coating used coating comprises modified resin 10 weight parts; Emulsion 70 weight parts; Filler 10 weight parts; Defoamer 0.1 weight part; Wetting agent 0.1 weight part; Pigment 1 weight part; It is 1000CPS, and the pH value is 8; the cloth base is calendere...

Embodiment 3

[0076] Compared with Example 2, the difference is that the stretch rate in the warp direction is 12%, and the shrinkage rate in the weft direction is 20%.

Abstract

The invention relates to a treatment method for a high-strength soft cloth base of an abrasive belt. The treatment method comprises the steps that rayon is adopted as a cloth base raw material for weaving; fluff on the surface of the cloth base is removed; the cloth base is stretched, wherein the warp-wise stretching rate is 6%-12%, and the weft-wise shrinkage rate is 8%-20%; the cloth base is impregnated in an impregnating tank containing a sizing material; the impregnated cloth base is dried at the temperature of 70-160 DEG C, and shaped at the high temperature of 160-190 DEG C; and after blade coating is conducted on the cloth base, the cloth base is dried at the temperature of 70-160 DEG C, calendered and rolled. According to the method, rayon weaving is adopted, and the double-strand filaments are adopted, so that the problem of protruding defects caused by weaving can be effectively solved, and production of P600 and fine gauze is guaranteed; after singeing, stretching is adopted to reduce the elongation of the cloth base; and a low-boiling-point solvent is firstly removed during drying, then high-temperature setting is performed to cure and mold the impregnated sizing material, the obtained sizing material layer is compact and uniform, and the defect that the low-boiling-point solvent is quickly gasified to form the sizing material layer due to direct high-temperature drying is avoided.

Description

technical field [0001] The invention relates to the field of cloth base for abrasive belts and its manufacturing method, in particular to a processing method and system for high-strength soft cloth bases for abrasive belts. Background technique [0002] The driven abrasive belt is mainly composed of substrate, binder and abrasive. The abrasive is in contact with the workpiece. The binder enables the abrasive to be fixed on the substrate. The substrate provides the basic physical properties of the abrasive belt to adapt to different workpiece environments, such as Wear resistance, heat resistance, extensibility, binding force with adhesive, etc., the commonly used base material is cloth base. In addition, the traditional soft cloth is usually mainly used for tearing cloth, the softness and cloth base strength cannot meet the requirements of abrasive belt application, and it is prone to breakage, elongation and other problems, so the cloth base needs to be treated. [0003] T...
