Abstract
Aiming at the condition that a loss factor, an applicable temperature range and a flame retardant property of a conventional rubber material cannot meet use requirements, the invention discloses a rubber material which is wide in applicable temperature range and high in loss factor, has the flame retardant property and can meet requirements of vibration isolation and noise reduction of electronic equipment. The flame retardant rubber material with the wide temperature range and the high loss factor comprises the components in a raw material weight ratio as follows: 100 parts of butyl rubber, 39-41 parts of phenolic resin, 4-6 parts of zinc oxide, 1.4-1.7 parts of stearic acid, 29-50 parts of carbon black N330, 9-11 parts of di-iso-octyl sebacate, 29-30 parts of small organic molecules 1010, 30-31 parts of aluminum hydroxide and 0.9-1.1 parts of a phenolic antioxidant D. According to the flame retardant rubber material with the wide temperature range and the high loss factor, tests show that a maximum loss primer is larger than or equal to 0.8, the loss primer is larger than or equal to 0.5 at the temperature ranging from subzero 10 DEG C to 80 DEG C, and the oxygen index is higher than or equal to 27%.
Description
Technical field:
Belong to high polymer material formulation design field, mainly as electronics vibration isolation and noise reduction elastomeric material.
Background technology:
Rubber is the effective way that suppresses vibration and attenuate acoustic noise, along with electronics is to high-performance, high precision future development, various electronicss are if computer, workstation, exchange board etc. are because fan and hard disk rotate vibration and the noise causing, the use of equipment and performance are brought and had a strong impact on, need more efficient terms of settlement, performance to elastomeric material is had higher requirement, and will have flame retardant properties.Domestic existing wide its maximum loss factor of temperature range elastomeric material is generally in 0.3 left and right, and temperature corresponding to dissipation factor peak value is generally below 0 ℃, and Applicable temperature is generally+20～+ 80 ℃ of left and right, cannot meet the demand that applicable for temperature field width and dissipation factor are high.
Summary of the invention:
For existing elastomeric material dissipation factor and applicable temperature range, flame retardant properties, cannot meet the situation of service requirements, the present invention proposes a kind of applicable for temperature field width, dissipation factor is high and there is the elastomeric material of flame retardant properties, meet electronics vibration insulation and noise reduction demand.
The high dissipation factor fire-retardant rubber material of a kind of wide temperature range, comprise following component, described proportioning is raw-material weight ratio: isoprene-isobutylene rubber component 100, resol component 39～41, zinc oxide component 4～6, stearic acid component 1.4～1.7, carbon black N330 component 29～50, diisooctyl sebacate component 9～11, organic molecule 1010 components 29～30, aluminium hydroxide component 30～31, phenolic type antioxidant D component 0.9～1.1.
The high dissipation factor fire-retardant rubber material of a kind of wide temperature range of the present invention, after tested, maximum loss introduction >=0.8, at-10～+ 80 ℃ of temperature range internal loss factor >=0.5, oxygen index >=27%.Take this rubber is that the vibration isolator of starting material compacting is applied on certain electronics, its random vibration acceleration responsive value 16g before vibration isolation is not reduced to 4g, in this equipment work temperature range, there is good vibration isolating effect, and its flame retardant properties meets equipment design requirements.
