Problems solved by technology

[0007] Glass microspheres are widely used as an excellent filler for composite materials, but glass microspheres are inorganic fillers with few surface active hydroxyl groups, weak interfacial bonding with the rubber matrix, and poor dispersion in rubber. The comprehensive mechanical properties of the filled rubber drop significantly, and the performance deteriorates rapidly during use, which has a negative impact on the use of tires

preparation example Construction

[0051] The present invention also provides a method for preparing modified glass microspheres, comprising: cleaning the glass microspheres in the first step, adding the glass microspheres into deionized water, stirring, filtering, adding to absolute ethanol, stirring, and standing for 12 hours, Filter and dry for use; the second step is to hydrolyze the sulfur-containing organosilicon compound, put the sulfur-containing organosilicon compound, distilled water, and acetic acid into a beaker according to the mass ratio of 1:0.2:0.02, and hydrolyze at room temperature for 1 hour under magnetic stirring Add a certain amount of absolute ethanol (the mass ratio of absolute ethanol to the sulfur-containing organic compound is 100:1); in the third step, the glass beads are grafted with the sulfur-containing organosilicon compound, and a certain amount of glass beads (the glass beads and the sulfur-containing organic compound) are weighed. Sulfur-organic compound (mass ratio: 100:1) is ...

Embodiment

[0058] Each component was weighed according to the proportions of Examples 1-3 in Table 1, and elastic inner support body materials were prepared according to the above-mentioned preparation method.

[0059] Adjust the speed of the internal mixer to 55 rpm, add raw rubber composed of natural rubber and polybutadiene rubber, press the top bolt for 30 seconds, lift the weight, add zinc oxide, stearic acid, and carbon black, and put the internal mixer Adjust the speed to 50 rpm, press the top bolt for 40 seconds, lift the weight, adjust the speed of the internal mixer to 45 rpm, press the bolt for 40 seconds, lift the weight, press the top bolt for 25 seconds, and remove glue at 165°C; open the mixer Unloading, cooling and stacking;

[0060] Adjust the speed of the internal mixer to 50 rpm, add a section of masterbatch, press the top bolt for 15 seconds, lift the mound, add anti-aging agent and protective wax, adjust the speed of the internal mixer to 45 rpm, and press the top bo...

Abstract

The invention relates to the technical field of military automobiles and particularly relates to a formula and preparation process of a lightweight elastic inner support body. The formula contains the following components in parts by weight: 80-100 parts of natural rubber, 0-20 parts of polybutadiene rubber, 50-70 parts of carbon black, 10-40 parts of a modified glass bead pre-dispersion master batch, 4.5-7.5 parts of an active agent, 3-8 parts of rubber operation oil, 1.5-6.5 parts of an anti-aging agent, 1.0-2.5 parts of protecting wax, 0.5-2.5 parts of an accelerant and 0.8-1.8 parts of sulfur. The important physical properties of a rubber material of the elastic inner support body are improved, meanwhile, the formula density of the lightweight elastic inner support body can be reduced, the volume weight can be reduced, and the light weight of a military bulletproof safety tread is realized; the elastic inner support body has the characteristics of high strength, low themogenesis, ageing resistance and light weight.

Description

technical field [0001] The invention relates to the technical field of military vehicles, in particular to a lightweight elastic inner support formulation and a preparation process thereof. Background technique [0002] The anti-breakage of military vehicle tires and the safe driving performance after damage have a crucial impact on the survivability of vehicles on the battlefield. In wartime, due to the complex driving areas and the hail of bullets on the battlefield environment, various wheeled military vehicles deployed by the troops may be attacked from the air and the ground at any time, and are vulnerable to man-made damage. At the same time, modern warfare will force military vehicles to drive more on the ground with complex terrain and no roads, which requires high off-road passing performance and safety protection performance of military vehicle tires. Therefore, high-performance military safety tires must meet two conditions: one is that the vehicle equipped with ...
