Embodiment Construction

[0017] An activated reclaimed rubber powder / PVC blended damping material, which is prepared from the following raw materials in parts by weight: 40 parts of PVC, 50 parts of activated reclaimed rubber powder, 0.5 parts of sulfur, 5 parts of petroleum asphalt, maleic anhydride grafted ethylene glycol 1 part of propylene rubber, 3 parts of hollow fiber, 1 part of rubber oil, 0.1 part of anti-aging agent.

[0018] Wherein the activated regenerated waste rubber powder is prepared by the following method;

[0019] (1) Mix 30-mesh waste rubber powder and desulfurization regenerant at a weight ratio of 10:1, put it into the desulfurization tank, feed high-temperature steam to keep the pressure in the tank at 0.5MPa, heat to 120°C, and use 500 rpm Premix at a speed of 5 min, then raise the temperature to 180°C, raise the pressure to 3 MPa, stir and react at a speed of 100 rpm for 30 min, and then release the pressure to obtain desulfurized reclaimed rubber powder;

[0020] (2) Put th...

Abstract

The invention discloses an activated reclaimed rubber powder/PVC blended damping material and a preparation method thereof. In the invention, waste rubber powder is desulfurized and activated, and blended with PVC to prepare a composite material with good damping performance. The surface of waste rubber powder after activation treatment has active groups, and the reactivity is enhanced, so as to realize the efficient reuse of waste rubber powder and replace traditional rubber damping materials, effectively reducing production costs. Under the action of compatibilizer, the compatibility between recycled waste rubber powder and PVC is better, and the modification effect on PVC is remarkable. At the same time, under the auxiliary effect of petroleum asphalt, hollow fiber and other materials, the various components work together to finally obtain shockproof, The composite damping material with noise reduction, high elasticity and wide temperature range has low production cost and simple process, and has great application prospects in the fields of automobiles and construction.

Description

technical field [0001] The invention relates to the technical field of damping materials, in particular to an activated regenerated rubber powder / PVC blended damping material and a preparation method thereof. Background technique [0002] my country is a big country in tire production and automobiles. With the rapid increase of family car ownership, a large number of waste tires are produced every year. How to effectively recycle these waste tires and prevent environmental pollution has very important practical significance and huge economic value. . At present, the more common waste tire recycling methods mainly include direct utilization of prototypes, heat generation by incineration, retreading of old tires, production of recycled rubber, and production of vulcanized rubber powder. Among them, the production of rubber powder is the most common processing method, which is widely used in the fields of modified asphalt, road paving, and rubber products paving in sports venue...
