Novel nanoscale high molecular memory material and preparation method thereof

Abstract

The invention relates to a novel nanoscale high molecular memory material and a preparation method thereof. The preparation method comprises the following steps: preparation of paste: fully grinding rosin pentaerythritol ester, terpene resin, diethyl phthalate, N'-diphenyl p-phenylenediamine aluminum hydroxide, nano calcium carbonate, 4, 4'-dibenzoxyl sulfur hydrazine and N, N-dimethyl ethylamino ethylene glycol, hydrolyzing under an acidic or alkaline condition, then adding an SEPS (Styrene-Ethylene / Propylene / Styrene) thermoplastic elastomer and polyisoprene rubber, adding to above melting point, mixing and stirring till no macroscopic particles are founded, thus obtaining the paste; high-seed rotating centrifugation: cooling the paste to room temperature, carrying out high-seed rotating centrifugation in a centrifugal machine; vacuumizing and drying: vacuumizing and drying the centrifugalized paste; and curing: taking out the centrifuged and dried paste and curing the centrifuged and dried paste for 24 hours under a room temperature condition to obtain the nanoscale high molecular memory material.

Description

technical field [0001] The invention relates to a novel nanoscale polymer memory material and a preparation method thereof. Background technique [0002] As consumers have higher and higher requirements for the safety performance of automobile tires, various safety tires appear. Therefore, the technology of spraying the polymer material layer inside the tire to achieve explosion-proof, leak-proof, and even bullet-proof effects has emerged. The adhesion is small, and air leakage will still occur after long-term use, which will affect driving safety. Therefore, a new type of leak-proof sealing material is needed to solve this problem. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a novel nanoscale polymer memory material with small molecular distance and strong adhesion, which can be used for leak-proof and tight repair of tires, and its preparation method. [0004] A method for preparing a novel nanoscale poly...
