Problems solved by technology

This traditional process has a certain effect on reducing the dyeing cost of phenolic molding compounds; but it has certain limitations on the dispersion and utilization of carbon black
The main disadvantages are as follows: (1) The dosage is relatively large; (2) The dispersion is uneven; (3) The appearance of the product is not beautiful; (4) The product is brittle; (5) It affects the curing speed of phenolic resin; (6) It is easy to pollute the production process
[0005] According to market research, there is currently no product that uses pigment carbon black to replace oil-soluble aniline black and carbon black in the production of phenolic molding compounds and achieves relatively satisfactory results.

Abstract

The invention provides a phenolic resin black function master batch and a preparation method thereof. The phenolic resin black function master batch is prepared from the following raw materials by weight: 200 parts of phenyl hydroxide, 148 to 152 parts of formaldehyde, 2 to 10 parts of a catalyst, and 4 parts of a composite functional black coloring agent. The preparation method comprises the following steps: first, adding molten phenyl hydroxide into a three-mouth beaker equipped with a stirrer, a condenser and a thermometer, adding formaldehyde according to the weight ratio, and carrying out stirring and heating to ensure that the temperature of the reaction system is 100 to 104 DEG C; adding the catalyst according to the weight ratio for a 1 to 2 hours' reaction when the liquid flows back; adding the composite functional black coloring agent according to the weight ratio when the liquid becomes turbid, carrying out a backflow reaction for 1.5 to 2 hours, dehydrating under decompression, carrying out a polycondensation synthesis reaction when the viscosity of resin reaches up to a certain value, discharging fast after the polycondensation synthesis reaction is finished, and carrying out cooling and smashing for treatment. The master batch is good in dyeing property and flowability, can be added with an optional quantity, and can be used for improving toughness effect and rising heat distortion temperature, so that the comprehensive performance is improved remarkably.

Description

technical field [0001] The invention relates to a phenolic resin black functional masterbatch and a preparation method thereof, in particular to a phenolic resin black functional masterbatch using nano-material modified pigment carbon black as a dyeing agent and a preparation method thereof. Background technique [0002] Phenolic resin is a polymer material that is polymerized with phenol and formaldehyde as raw materials under the condition of acidic catalyst (or basic catalyst). Its production process is stable and easy to operate, the price of raw materials is low, and it has many advantages such as good heat resistance, electrical insulation, corrosion resistance, low smoke generation, and product dimensional stability. Therefore, phenolic molding compound (commonly known as bakelite powder) with phenolic resin as the main raw material is widely used in many fields such as household appliances, household cooking utensils, aerospace, and automobile industry. Among the ma...
