Embodiment 1

[0017] The invention provides an oil-resistant paper-based friction sheet, which comprises the following materials in mass fractions: compounding agent: 0.8-1.2; sulfur: 2.5-5.5; filler: 44-73; adhesive: 20-28; nitrile rubber: 10 ~14.

[0018] The oil-resistant paper-based friction sheet in the present invention increases the oil resistance of the friction sheet by using nitrile rubber, and at the same time ensures other physical properties and mechanical properties of the friction sheet, has a high friction coefficient and is resistant to oil. The lower friction performance remains the same.

[0019] Optionally, the compounding agent includes the following materials in mass fraction: Accelerator: 0.4-0.6; Anti-aging agent: 0.4-0.6.

[0020] Optionally, the filler includes materials with the following mass fractions: zinc oxide: 1.5-3.5; carbon black: 6-10; graphite: 6-10; chromite powder: 6-10; petroleum coke powder: 3-5 ; Precipitated barium sulfate: 16~20; Coumarone: 2.5~...

Embodiment 2

[0025] The present invention also provides a production method of the above-mentioned oil-resistant paper-based friction plate, the flow chart is as follows figure 1 shown, including steps:

[0026] S101: putting the nitrile rubber into an internal mixer for masticating;

[0027] S102: Put the compounding agent, sulfur, filler, adhesive and masticated nitrile rubber into an internal mixer for mixing to form a mixed rubber;

[0028] S103: moving the mixed rubber into an open rubber mixing machine, and making the mixed rubber pass through the rollers of the open rubber mixing machine to form a film;

[0029] S104: Wrap a film around the film for isolation.

[0030] The production method in the present invention is aimed at the production method of the above materials, and the produced paper-based friction sheet has high friction coefficient, stable friction performance and certain friction performance under the condition of oil immersion.

[0031] Optionally, in the step S101...

Abstract

The invention relates to an oil-resistant paper-base friction plate and a production method thereof. The oil-resistant paper-base friction plate comprises the following materials in parts by weight: 0.8-1.2 parts of compounding agent, 2.5-5.5 parts of sulfur, 44-73 parts of filler, 20-28 parts of adhesive and 10-14 parts of butadiene-acrylonitrile rubber. The method comprises the following steps: S101: plastifying the butadiene-acrylonitrile rubber in a Banbury mixer; S102: adding the compounding agent, sulfur, filler, adhesive and plastified butadiene-acrylonitrile rubber into the Banbury mixer, and compounding to form the compounded rubber; S103: moving the compounded rubber into an open rubber mixing mill to form a rubber plate; and S104: winding a film outside the rubber plate for isolation. The production method can ensure the oil resistance of the friction material. The frictional property of the friction plate subjected to oil impregnation is the same as before oil impregnation, thereby simultaneously ensuring the stable frictional property and higher friction factor of the paper-base friction plate.

Description

technical field [0001] The invention relates to the field of friction plates, in particular to an oil-resistant paper-based friction plate and a production method thereof. Background technique [0002] Friction materials are mainly composed of fibers, binders, fillers, and friction modifiers, and are usually produced by papermaking, so they are called paper-based friction materials. Because of its high friction coefficient, stable friction performance, adjustable dynamic and static friction coefficient ratio, good wear resistance, high energy absorption capacity and many other excellent properties, it is widely used in various heavy vehicles and engineering vehicles. Traditional clutch facings are mainly used for dry clutches, not suitable for wet clutches. Contents of the invention [0003] A brief overview of the invention is given below in order to provide a basic understanding of some aspects of the invention. It should be understood that this summary is not an exhau...
