Embodiment 1

[0040] On the 1000 ml four-neck reaction flask, install stirring, thermometer, reflux condenser and addition funnel. Add 300 g of p-tert-butylphenol, 194 g of 37% formaldehyde solution, and 2 g of triethylamine catalyst. The temperature was raised to 80°C. 21 g of morpholine was added dropwise through the addition funnel. Reflux for 2 hours. Normal pressure dehydration. When the temperature rises to 170° C., add 80 g of rosin and 40 g of stearic acid. Remove residual water to 180°C, and keep it warm at this temperature for 2 hours. Add FePc 3g. The temperature was raised to 200°C and maintained at this temperature for 2 hours. Drain the resin mass into a stainless steel pan and cool to room temperature. The product is transparent, the softening point is 125℃, dark green.

Embodiment 2

[0042] On the 1000 ml four-neck reaction flask, install stirring, thermometer, reflux condenser and dropping funnel. Add 300 g of p-tert-butylphenol, 194 g of 37% formaldehyde solution, and 2 g of triethylamine catalyst. The temperature was raised to 80°C. 28.1 g of 2-hydroxymethylmorpholine was added dropwise through the addition funnel. Reflux for 2 hours. Normal pressure dehydration. When the temperature rises to 170° C., add 80 g of rosin and 40 g of stearic acid. Remove residual water to 180°C, and keep it warm at this temperature for 2 hours. Add FePc 1.5g. The temperature was raised to 200°C and maintained at this temperature for 2 hours. Drain the resin mass into a stainless steel pan and cool to room temperature. The softening point of the product is 125°C, blue.

Embodiment 3

[0044] On the 1000ml four-neck reaction flask, install stirring, thermometer, reflux condenser and addition funnel. Add 300 g of p-tert-butylphenol, 194 g of 37% formaldehyde solution, and 2 g of triethylamine catalyst. The temperature was raised to 80°C. 26 g of aniline was added dropwise through the addition funnel. Reflux for 2 hours. Normal pressure dehydration. When the temperature rises to 70°C, add 80g of rosin and 40g of stearic acid. Remove residual water to 180°C, and keep warm at this temperature for 1 hour. Add FePc 1.5g. The temperature was raised to 200°C and maintained at this temperature for 2 hours. Drain the resin mass into a stainless steel pan and cool to room temperature. The product is transparent, with a softening point of 136°C and dark blue.

Abstract

The invention provides a multifunctional phenolic resin for a rubber industry and a manufacture method thereof. Nitrogen-containing compound is introduced to a condensation resin structure of alkylphenol and aldehyde. Phthalocyanine iron (II), abietic acid, and fatty acid which have chemical peptized activity and contained in rubber are improved so that rubber peptization is improved and the rubber has the best self-adhesive property and retainability.

Description

technical field [0001] The invention relates to a multifunctional phenolic resin for rubber industry, in particular to a preparation method of the multifunctional phenolic resin. Background technique [0002] There are two types of rubber, namely natural rubber and synthetic rubber, both of which are important raw materials for economic development in the world today. The annual consumption of rubber in the world has reached more than 24 million tons, of which synthetic rubber accounts for about 60%, and is widely used in the manufacture of tires, rubber hoses, conveyor belts, various laminated products and model products. Since synthetic rubber undergoes chemical treatments such as termination, salting out, coagulation and anti-aging in the synthetic process, the self-adhesiveness of synthetic rubber is far inferior to that of natural rubber, which brings great difficulties to the processing technology of rubber products. The purpose of developing rubber tackifying resin i...
