Embodiment 1

[0025] 1. Drying treatment with non-asbestos cloth, so that the adsorbed moisture content is ≤1.5%.

[0026] 2. Configure resin alcohol solution,

[0027] ① Phenolic resin: hexamethylenetetramine: alcohol = 1:1:5.

[0028] ②Correctly mix phenolic resin and hexamethylenetetramine in proportion according to the output, crush them and crush them with an F-400 pulverizer.

[0029] ③Put the crushed resin and alcohol into the blender in proportion to make a resin solution.

[0030] 3. Asbestos-free cloth impregnated with resin,

[0031] ① Put the prepared resin alcohol solution into the dipping machine tank.

[0032] ②Try to start the machine for 2 to 3 minutes. After confirming that the equipment is working normally, pass the asbestos cloth between the two rollers, adjust the roller distance, and control the resin content.

[0033] ③The resin content is controlled at 18-22%, and the volatile matter is 2-3.5%.

[0034] Calculation method of resin content:

Abstract

A novel environmental-friendly wear and high-temperature resistant friction plate relates to the field of production and processing of automobile parts; a technological process comprises the following steps of: drying asbestos-free cloth; preparing a resin alcoholic solution, wherein the ratio of phenolic resin to hexamethylene tetramine to alcohol is 1:1:5; dipping the asbestos-free cloth by resin; orderly airing the asbestos-free cloth dipped with the resin on a material frame; starting a rubber mixing mill, adjusting the roller spacing to be 1-2mm, and placing styrene-butadiene rubber on a rubber mixing mill for mastication; adding an accessory ingredient padding for mixing; adding a solvent naphtha padding for pulping; carrying out rubber dipping on the asbestos-free cloth dipped with the resin through a rubber dipping machine; tailoring the asbestos-free cloth dipped with a sizing material, and winding the tailored asbestos-free cloth on a blank; putting the blank wound with the asbestos-free cloth in a pressing machine, and carrying out hot-press forming on the blank; putting the formed blank in a drying oven for carrying out thermal treatment; after finishing the thermal treatment, polishing the product with a machine tool; and checking the packaging and putting the product in storage. The novel environmental-friendly wear and high-temperature resistant friction plate has the beneficial effects of environmental friendliness, abrasion resistance and high temperature resistance.

Description

Technical field: [0001] The invention relates to the field of production and processing of auto parts, in particular to a production process of automobile clutch friction plates, in particular to a production process of a novel environmentally friendly, wear-resistant and high-temperature resistant friction plate. Background technique: [0002] At present, there are many kinds of applications for automobile clutch friction plates in the domestic and foreign markets, and at the same time, customers' requirements for the performance of friction plates are also increasing. At present, the additive materials of clutch friction plates in the same industry are generally of low grade, and they are all some mineral materials, and different mineral materials are also divided into good and bad, and the effects of adding them are also different. The friction plate must first meet the requirements of wear resistance and high temperature resistance. Wear resistance refers to the service ...
