Embodiment 1

[0021] Add 0.225g of silane coupling agent KH-5500 (the coupling agent accounts for 1.5% of the lignocellulose mass) in a 1000ml beaker, dilute with 8ml of absolute ethanol, add 750ml of deionized water, then add 15g of lignocellulose, and stir for 30min. To obtain a lignocellulose suspension, add montmorillonite DK-330g, mix and heat to 80°C, react for 6 hours, wash the reaction product until neutral, dry, and ball mill to below 120 mesh to obtain lignocellulose and montmorillonite Lignocellulose / montmorillonite rubber reinforcing agent with a soil mass ratio of 1:2.

Embodiment 2

[0023] Add 0.225g of silane coupling agent KH-5500 (the coupling agent accounts for 1.5% of the lignocellulose mass) in a 1000ml beaker, dilute with 8ml of absolute ethanol, add 750ml of deionized water, then add 15g of lignocellulose, and stir for 30min. To obtain a lignocellulose suspension, add montmorillonite DK-345g, mix and heat to 80°C, react for 6 hours, wash the reaction product until neutral, dry, and ball mill to below 120 mesh to obtain lignocellulose and montmorillonite Lignocellulose / montmorillonite rubber reinforcing agent with a soil mass ratio of 1:3.

Embodiment 3

Abstract

The invention discloses a preparation method of a lignocellulose / montmorillonite rubber reinforcing agent and a rubber reinforcing method. The preparation method of the lignocellulose / montmorillonite rubber reinforcing agent comprises the following steps of dispersing a silane coupling agent into anhydrous ethanol, diluting the mixture by adding deionized water, and adding lignocellulose to be uniformly stirred to obtain lignocellulose suspension liquid; and adding montmorillonite into the lignocellulose suspension liquid to be reacted for 4-8 hours in a stirring manner at the temperature of 80 DEG C, washing the reaction product to be neutral after the reaction is ended, and drying and ball-milling the reaction product to obtain the lignocellulose / montmorillonite rubber reinforcing agent. The rubber reinforcing agent prepared from the lignocellulose and the montmorillonite is rich in raw materials, simple in preparation process and capable of substituting partial carbon black, a reinforcing effect similar to the carbon black can be obtained and the consumption of petrochemical resources is reduced; the lignocellulose / montmorillonite rubber reinforcing agent is an environment-friendly material.

Description

1. Technical field [0001] The invention relates to a preparation method of a lignocellulose / montmorillonite rubber reinforcing agent and a rubber reinforcing method. 2. Background technology [0002] Carbon black is widely used as an important reinforcing agent in the manufacture of tires and other rubber products. As the most traditional reinforcing agent, carbon black does have an irreplaceable position, but it also has unavoidable shortcomings such as high pollution, high energy consumption, and dependence on petroleum resources. [0003] With the continuous shortage of oil and gas resource supply and the deepening of human understanding of environmental pollution and energy crisis, the preparation of renewable and degradable polymer materials with natural renewable resources as raw materials has attracted more and more attention. Lignocellulose is the most abundant natural renewable resource on the earth. It is rich in various functional groups and has high reactivity, ...
