Embodiment Construction

[0017] The automobile friction lining with flame-retardant function of the present invention is composed of 10-16 parts by weight of phenolic resin, 28-35 parts of steel wool, 3-8 parts of coke, 3-10 parts of mineral fiber, and nano 4-8 parts of magnesium oxide, 15-20 parts of barium sulfate, 10-18 parts of graphite, 2-6 parts of potassium feldspar, and 0.5-2 parts of zinc borate. The automobile friction lining with flame-retardant function of the present invention adds nano-scale magnesium oxide to its components, and the nano-scale magnesium oxide is an excellent resistance material with obvious small size effect, surface effect, quantum size effect and macroscopic tunnel effect. combustible substance. Compared with some traditional organic flame retardants containing phosphorus or halogens, nano-magnesia is non-toxic, tasteless, and has a small amount of addition. It is an ideal host material for compound flame retardants.

Abstract

The invention provides an automobile friction lining with a flame-retardant function and a production method of the automobile friction lining in order to solve the problem such as braking failure resulted from heating decomposition easily existing in a friction material of a disc brake in the prior art. The friction material comprises the components in percentage by weight: 10-16 parts of phenol-formaldehyde resin, 28-35 parts of steel wool, 3-8 parts of cokes, 3-10 parts of mineral fibers, 4-8 parts of nanoscale magnesium oxide, 15-20 parts of barium sulfate, 10-18 parts of graphite, 2-6 parts of potassium feldspar and 0.5-2 parts of zinc borate. The automobile friction lining with the flame-retardant function and the production method of the automobile friction lining have the beneficial effects of raising the thermal cracking temperature of a brake pad, eliminating the hidden danger of braking failure caused by high braking temperature and achieving the technical effect of replacing a powder metallurgy brake pad on the premise that the braking performance of the brake pad completely meets relevant standard requirements.

Description

[0001] field of invention [0002] The invention relates to the production technology of automobile friction materials, in particular to an automobile friction lining with flame-retardant function and a preparation method thereof. Background technique [0003] The development of automobile friction materials can be summed up by the word "advancing by leaps and bounds". The continuous emergence of new materials and new processes has provided a strong driving force for the development of this industry. At present, most of the friction materials on the market are organic friction materials based on high polymers. Organic friction materials are popular all over the world because of their simplified production process, cheap and easy-to-obtain raw materials, and high safety of equipment and tooling. However, the defect that high polymers are not resistant to high temperatures has become increasingly apparent with the development of high-speed and heavy-duty motor vehicles. The hi...
