Embodiment 1

[0058] (1) Add 10g (0.06mol) accelerator M and 50ml absolute ethanol to a 100ml four-necked round-bottomed reaction flask equipped with a mechanical stirrer, a thermometer, a reflux condenser and an exhaust gas absorption device, and add sodium hydroxide after completely dissolving Solution (2wt%), adjust the pH to 11, keep the temperature at 10-12°C, slowly feed chlorine gas, and feed according to the molar ratio of promoter M and chlorine gas at 1:1. After the gas feeding was completed, the temperature was raised to 45° C., and the reaction was carried out for 1 hour. During the reaction, sodium hydroxide was continuously added to maintain a slightly alkaline environment (pH=8-11). Then, the reaction solution was poured into 500 g of cold water, allowed to stand for 1 hour, filtered, washed with cold water, and dried at 50° C. to obtain intermediate compound Z.

Abstract

The invention discloses accelerator M modified alkylphenol-formaldehyde resin, and a preparation method and application thereof. The resin is obtained by carrying out a reaction on a reaction productof an accelerator M and chlorine with alkylphenol-formaldehyde resin under an alkaline condition. According to the invention, the accelerator M is used as a modifier, an intermediate compound Z whichcan easily react with resin is generated through a one-step reaction, and then the intermediate compound Z is mixed with the alkylphenol-formaldehyde resin for modification. The method provided by theinvention has a simple process and a high atomic utilization rate, adhesion performance of the obtained modified resin is obviously improved, performance of the modified resin is obviously better than performance of traditional tackifying resin, and tackifying durability and damp-thermal viscosity performance of the modified resin are obviously improved.

Description

technical field [0001] The present invention relates to a modified alkylphenol-formaldehyde resin, in particular to a modified alkylphenol-formaldehyde resin with strong viscosifying durability, high wet-heat viscous performance, and little influence on the vulcanization performance of the rubber compound and its preparation method and The application as tackifying resin for rubber belongs to the technical field of alkylphenol formaldehyde tackifying resin. Background technique [0002] Radial tires are commonly known as "steel tires". It is a new type of tire in which the carcass cords are arranged in the meridian direction, and the buffer layer arranged in the circumferential direction or close to the circumferential direction of the cords is tightly hooped on the carcass. The bonding strength of rubber and steel wire in the tire greatly affects the quality of the radial tire. Therefore, self-adhesion is very important in the molding process, so it is also called molding ...
