Problems solved by technology

It is easy to loosen when the cast iron bearing seat is closely matched with the idler tube body
In this way, the metal bearing seat is used at the same time, which has poor shock absorption effect, poor toughness, and poor waterproof performance, thereby affecting the service life of the bearing seat, and the production cost is also greatly increased.

Embodiment 1

[0014] The nylon composition for the bearing seat is characterized in that, by weight percentage, it consists of the following components:

[0015] Nylon 6 80%

[0016] Decabromodiphenyl ether 9%

[0017] Antimony trioxide 4%

[0018] Zinc borate 2%

[0019] Carbon black 5%

[0020] After the above raw materials are mixed evenly, they are added to a granulator to granulate, and the obtained granules are melted and injected into the mold of the bearing seat to obtain the required nylon bearing seat.

Embodiment 2

[0022] The nylon composition for the bearing seat is characterized in that, by weight percentage, it consists of the following components:

[0023] Nylon base 93.5%

[0024] Decabromodiphenyl ether 4%

[0025] Antimony trioxide 1%

[0026] Zinc borate 0.5%

[0027] Carbon black 1%

[0028] After the above raw materials are mixed evenly, they are added to a granulator to granulate, and the obtained granules are melted and injected into the mold of the bearing seat to obtain the required nylon bearing seat.

Embodiment 3

[0030] The nylon composition for the bearing seat is characterized in that, by weight percentage, it consists of the following components:

[0031] Nylon base 89%

[0032] Decabromodiphenyl ether 5%

[0033] Antimony trioxide 2%

[0034] Zinc borate 1%

[0035] Carbon black 3%

[0036] After the above raw materials are mixed evenly, they are added to a granulator to granulate, and the obtained granules are melted and injected into the mold of the bearing seat to obtain the required nylon bearing seat.

Abstract

The invention discloses a nylon composite for a bearing pedestal, which is characterized in that the nylon composite comprises the following components in percentage by weight: 80 to 93.5 percent of nylon base material, 4 to 9 percent of decabromodiphenyl ether, 1 to 4 percent of antimonous oxide, 0.5 to 2 percent of zinc borate and 1 to 5 percent of carbon black. The invention has high strength and high toughness as well as waterproof performance and flame retardant property.

Description

technical field [0001] The present invention relates to a composition, in particular to a nylon composition for a bearing housing. Background technique [0002] Traditional bearing housings are generally made of cast iron or stamping parts, and gas shielded welding between stamped bearing housings and roller tubes is prone to shrinkage and weld seams. It is easy to loosen when the cast iron bearing seat is closely matched with the idler tube body. In this way, the metal bearing seat is adopted at the same time, which has poor shock absorption effect, poor toughness, and poor waterproof performance, thereby affecting the service life of the bearing seat, and the production cost is also greatly increased accordingly. Contents of the invention [0003] The purpose of the present invention is to provide a nylon composition ingredient that can make the bearing seat have good waterproof performance, strong shock resistance and high toughness. [0004] In order to solve the abo...
