Abstract

The invention discloses a preparation method of a halogen-free rubber foam insulation material. The preparation method comprises the following steps: mixing an ethylene-propylene-diene monomer with ethylene propylene, adjusting the temperature to 110-120 DEG C, and performing a stirring reaction for 20-30 minutes; further adding polyvinyl chloride, polydipentanone and methyl magnesium chloride, adjusting the temperature to 120-125 DEG C, and performing a reaction for 15-25 minutes; further adding polycaprolactone and trioctyl phosphate, adjusting the temperature to 128-132 DEG C, and performing a reaction for 20-30 minutes continuously; adding 2-methyl-6-isopropyl phenylamine, aluminum silicate and azodicarbonamide, and leaving to stand at 135-140 DEG C to react for 30-40 minutes; further performing a stirring reaction for 20-30 minutes at a velocity of 800-900r / minute; cooling after the reaction, drying, and pelletizing, thereby obtaining the halogen-free rubber foam insulation material. The halogen-free rubber foam insulation material prepared by using the method is good in both flame retardancy and heat preservation.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, in particular to a halogen-free rubber and plastic foam thermal insulation material and a preparation method thereof. Background technique [0002] The traditional thermal insulation materials are mainly to increase the gas phase void ratio and reduce the thermal conductivity and conductivity coefficient. In order to increase convective heat transfer and radiation heat transfer in the use environment, fiber-based thermal insulation materials must have a thicker coating; while profile-based inorganic thermal insulation materials need to be assembled and constructed, there are many seams, which damage the appearance and waterproof. Poor performance, short service life and other defects. The promulgation and implementation of rubber and plastic insulation materials and products, and energy-saving regulations are the influencing factors affecting building energy conservation, involving a ...
