Embodiment 1

[0020] Embodiment 1 Concrete production steps are as follows

[0021] Compound production

[0022] (1) Weigh various ingredients according to the specific formula ratio. Its rubber raw material components and proportions are: 120 parts of 18-type nitrile rubber, anti-aging agent NBC (Chinese name: N,N-dibutyldithioamino Nickel formate) 2 parts, FEF330 carbon black (Chinese name: fast extruded carbon black) 30 parts, zinc oxide 6 parts, magnesium oxide 9 parts, sulfur 1 part, spray carbon black 30 parts, o-dibutyl ester 20 parts, transformer 10 parts of oil, accelerator DM (Chinese name: 2,2'-dithiodibenzothiazole, molecular formula: C 14 h 8 N 2 S 4 ) 1 part. The weight unit of each part in the component is determined according to production needs, such as 1 kilogram per part.

[0023] (2) Add 18-type nitrile rubber according to the ratio of rubber raw materials in (1) and add it to the rubber mixer. After mixing for 2 minutes with the roller distance of the rubber mixer...

Embodiment 2

[0031] The production process of embodiment 2 is identical with embodiment 1, and difference is that the rubber material component ratio is different, and the rubber material composition of embodiment 2 is calculated as follows by component: 120 parts of 18 type nitrile rubbers, antioxidant NBC (Chinese name : N, N-dibutyl dithiocarbamate nickel) 2.3 parts, FEF330 carbon black (Chinese name: fast extrusion carbon black) 40 parts, zinc oxide 6 parts, magnesium oxide 9 parts, sulfur 1 part, spray carbon 30 parts of black, 20 parts of o-dibutyl ester, 10 parts of transformer oil, accelerator DM (Chinese name: 2,2'-dithiodibenzothiazole, molecular formula: C 14 h 8 N 2 S 4 ) 1 part.

Embodiment 3

[0032] The production process of embodiment 3 is the same as that of embodiment 1, and the difference is that the ratio of rubber material components is different. The rubber material components of embodiment 3 are calculated as follows by components: 13 parts of 18 type nitrile rubber, anti-aging agent NBC (Chinese name : N, N-dibutyl dithiocarbamate nickel) 3 parts, FEF330 carbon black (Chinese name: fast extrusion carbon black) 50 parts, zinc oxide 7 parts, magnesium oxide 9.5 parts, sulfur 1.1 parts, spray carbon 50 parts of black, 25 parts of o-dibutyl ester, 12 parts of transformer oil, accelerator DM (Chinese name: 2,2'-dithiodibenzothiazole, molecular formula: C 14 h 8 N 2 S 4 ) 1.1 parts.

Abstract

The invention provides a low compression and deformation rubber part. The rubber part comprises the following rubber raw material ingredients in weight ratio: 120-140 parts of No.18 butadiene rubber, 2-3 parts of antioxidant (Chinese name: N, N-dibutyldithiocarbamate), 30-50 parts of fast extruding furnace (FEF) 330 carbon black (Chinese name: fast extruding furnace carbon black), 6-8 parts of zinc oxide, 9-10 parts of magnesium oxide, 1-1.2 parts of sulfur, 30-40 parts of spray carbon black, 20-30 parts of dibutyl phthalate, 10-15 parts of transformer oil and 1-1.2 parts of accelerant DM (Chinese name: 2, 2'-dithio-dibenzo thiazole). The rubber formula takes the No.18 butadiene rubber with good compression resistance as a main material, so that the vulcanization efficiency is increased, a three-dimensional network structure is improved, and the rubber part has good elasticity under compression.

Description

technical field [0001] The invention relates to the field of rubber, in particular to low compression deformation rubber parts. Background technique [0002] In the production process of mechanical seal equipment, there are relatively high requirements on the compression resistance of rubber. The existing products cannot rebound due to compression during production, resulting in poor sealing effect. Contents of the invention [0003] The object of the present invention is to provide a method to improve the compression deformation resistance of rubber parts and improve the problem of inability to rebound due to long-term compression. [0004] The technical solution of the present invention is to provide low-compression deformation rubber parts, which are characterized in that: its rubber raw material components and weight ratio are selected as 120-140 parts of 18-type nitrile rubber, anti-aging agent NBC (Chinese name: N, N -Nickel dibutyldithiocarbamate) 2~3 parts, FEF330...
