Embodiment 1

[0047] The preparation method of the environment-friendly flame-retardant butyl rubber and EPDM multi-component blended closed-cell secondary foaming material comprises the following steps:

[0048] (1) Butyl rubber mastication: put 100PHR of butyl rubber and 0.2PHR of stearic acid into a 75L diamond-shaped leaf shaft W-type heavy hammer internal mixer, pressurize to 7 kg, and knead for 10 minutes. Continuously fill with cold water to cool down, and when the temperature reaches 110°C, the butyl rubber is discharged to obtain butyl rubber; put the butyl rubber into the 18-inch automatic turning mill, the temperature is controlled at 85°C, and the 5mm turning is 180 seconds , thin through 2mm thickness fluttering cut into the corresponding weight respectively static processing;

[0049](2) EPDM rubber refining: Put 100PHR of EPDM rubber and 0.1PHR of stearic acid into a 75L diamond-shaft W-type hammer internal mixer, pressurize to 7 kg, and knead for 10 minutes , during the kne...

Embodiment 2

[0059] The preparation method of the environment-friendly flame-retardant butyl rubber and EPDM multi-component blended closed-cell secondary foaming material comprises the following steps:

[0060] (1) Butyl rubber mastication: put 100PHR of butyl rubber and 0.2PHR of stearic acid into a 75L diamond-shaped leaf shaft W-type heavy hammer internal mixer, pressurize to 7 kg, and knead for 10 minutes. Continuously fill with cold water to cool down, and when the temperature reaches 115°C, discharge to obtain butyl rubber mastic; put the butyl rubber mastic into the 18-inch automatic turning mill, control the temperature at 90°C, and turn 5mm for 180 seconds , thin through 2mm thickness fluttering cut into the corresponding weight respectively static processing;

[0061] (2) EPDM rubber refining: Put 100PHR of EPDM rubber and 0.1PHR of stearic acid into a 75L diamond-shaft W-type hammer internal mixer, pressurize to 7 kg, and knead for 10 minutes , during the kneading process, con...

Abstract

The invention relates to the technical field of foaming materials, and provides an environment-friendly inflaming retarding butyl rubber and ethylene propylene diene monomer rubber multielement blended blind-hole secondary foaming material and a preparation method thereof. Butyl rubber with low elasticity and excellent damping performance and air tightness and ethylene propylene diene monomer rubber with excellent weather fastness, ozone resistance, heat resistance, electrical insulating performance and chemical mediator corrosion resistance are subjected to compatible blending to form the multielement blended blind-hole foaming material with good comprehensive performance and low cost. Good vibration absorption performance and excellent air tightness brought by the low-elasticity characteristic and excellent damping performance of the butyl rubber are kept, and meanwhile the product passes the ROHS international environmental requirement and has the novel inflaming retarding property.

Description

technical field [0001] The invention relates to the technical field of foaming materials, in particular to an environmentally friendly flame-retardant butyl rubber and EPDM multi-component blended closed-cell secondary foaming material and a preparation method thereof. Background technique [0002] Butyl rubber, referred to as IIR, is the abbreviation of Isobutylene Isoprene Rubber. It has good chemical stability and thermal stability, the most prominent is air tightness and water tightness, its permeability to air is only 1 / 7 of that of natural rubber, 1 / 5 of that of styrene-butadiene rubber, and its permeability to steam The transmittance is 1 / 200 of natural rubber and 1 / 140 of styrene-butadiene rubber. Therefore, it is mainly used to manufacture various rubber products such as inner tubes, steam pipes, water tires, dam bottom layers and gaskets, pharmaceutical products and automobiles that require sealing and insulation, and automobile sound insulation products. [0003...
