Problems solved by technology

Although desulfurization can effectively remove the three-dimensional network structure and obtain reclaimed rubber, it is easy to form waste smoke and gas emissions, causing environmental pollution. Today, as environmental pollution control is becoming more and more stringent, it is not a good method for green utilization. disuse

Embodiment 1

[0032] The mass percentage of each component of the synergistic hybrid textile waste rubber-based damping vibration reduction composite material adopts TWRP:AO 2246:AO4426=70:30:0, and the preparation steps of the composite material are as follows:

[0033] The first step of mixing:

[0034] 1> Raise the temperature of the rollers on the double-roller plastic refining machine to 60°C and keep it basically stable;

[0035] 2>Add textile waste rubber powder (TWRP) between the rollers to form a film through the surface temperature of the rollers and the shearing action between the double rollers;

[0036] 3> After weighing the film-forming TWRP and AO 2246 according to the mass ratio of 70:30, first mix the TWRP film between the double rollers, then slowly add AO 2246, and use a cutter as an auxiliary mixing to make the components well mixed;

[0037] 4> The total mixing time is 40 minutes. After mixing evenly, the mixed material is peeled off from the roller and cooled at room...

Embodiment 2

[0044] The first step of mixing:

[0045] 1> Raise the temperature of the rollers on the double-roller plastic refining machine to 65°C and keep it basically stable;

[0046] 2> After weighing the material of Example 1 and AO 4426 according to the mass ratio of 90.9:9.1 (that is, TWRP:AO2246:AO 4426=63.6:27.3:9.1), the TWRP / AO 2246 (70 / 30) film Mix between the double rollers, then slowly add AO 4426, use a cutter as an auxiliary mixing to make the components evenly mixed;

[0047] 3> the total mixing time is 60 minutes (adding the total time of the material prepared in Example 1), after mixing evenly, the mixing material is peeled off from the roller, and cooled at room temperature to prepare for heating For pressing and forming.

[0048] The second step of thermoforming:

[0049] 1> Cut the cooled kneaded film into a size slightly larger than the inner cavity of the mold and lay it in the mold cavity. Mucous membranes are isolated;

[0050] 2> Move the steel plate into the...

Embodiment 3

[0054] The mass percentage of each component of the textile waste rubber-based damping and vibration-reduction composite material of synergistic hybridization adopts TWRP:AO 2246:AO4426=70:30:30=53.8:23.1:23.1, and the preparation steps of the composite material are the same as in Example 2, Its process is different from Example 2 in that the temperature is 70° C. when the raw materials are uniformly mixed on the double-roller plastic extruder, and the time is 80 minutes (plus the total time of preparing the material in Example 1). The sample was hot-pressed under a flat vulcanizing machine at a temperature of 165°C. The preheating time was 30 minutes without pressure, and the hot-pressing time was also 40 minutes. The pressure was 16Mpa. Finally, the material was taken out and cooled in ice water. Thus, a synergistic hybrid textile waste rubber-based damping composite material C with a thickness of 1 mm was prepared.

[0055] It was placed in liquid nitrogen for brittle fract...

Abstract

The invention discloses a synergic-hybridization textile waste rubber-base damping vibration-reduction composite material which comprises textile waste rubber powder, a hindered phenol antioxidant AO 2246 and a hindered phenol antioxidant AO 4426. The preparation method comprises the steps of compounding and hot pressing. The method specifically comprises the following steps: selecting a high-polarity three-dimensional-net-structure textile waste rubber powder (TWRP) as a base, adding the two polar functional organic micromolecules (AO 2246 and AO 4426), compounding uniformly, and carrying out hot pressing to obtain the waste rubber-base damping composite material. OHs of different organic micromolecules and the CH group of nitrile-butadiene rubber of the textile waste rubber generate reversible hydrogen bond, and OHs of different organic micromolecules can also generate reversible hydrogen bond, thereby implementing synergic hybridization. The reversible hydrogen bond network is formed in the material, so that the peak value of the dissipation factor of the material is increased, and the corresponding temperature is more suitable for practical application.

Description

technical field [0001] The invention belongs to the field of engineering materials, and it relates to a kind of textile waste rubber (abbreviated as TWRP) as a matrix, and utilizes the synergistic hybridization of two functional organic small molecules to develop a damping and vibration-reducing composite material, more specifically, its It involves the use of textile waste rubber to develop engineering materials with damping and vibration-reducing properties, so as to realize the functional development of waste materials under green processing conditions; and involves a new method of synergistic hybridization between functional organic small molecules to further improve the damping properties of materials . Background technique [0002] Textile, as the pillar industry of our country, has a large number of textile rubber rollers and aprons scrapped every year. Due to its three-dimensional network structure, it is difficult to biodegrade. Although desulfurization can effect...
