Embodiment 1

[0024] Add 32% of wood powder, 45% of phenolic resin, 7.5% of Hexa, 3% of magnesium oxide, 0.5% of slaked lime, 5% of talcum powder, 3% of calcium carbonate, 2% of calcium stearate, and 2% of oil black into the mixing Mix with normal temperature, add cashew nut oil and an equal amount of water to the mixed material to form an emulsion after vigorously stirring as a plasticizer, then mix for 5 to 20 minutes, use continuous operation roller pressing method, start the plastic refining machine and When it is attached to the equipment, the feeding bag is put down, and the temperature of the front roller is set to 80°C. The temperature of the rear roller is set at 135°C, so that the material slowly falls into the feeding end of the roller. When the roller is covered with a layer of material, the coulter can be put down. Send it to the conveyor belt to let it air-cool, and then break it after cooling.

Embodiment 2

[0026] Put 32% of bamboo powder, 40% of phenolic resin, 7.2% of Hexa, 2% of magnesium oxide, 0.8% of slaked lime, 14% of talcum powder, 2% of calcium stearate, and 2% of oil black into the mixer in turn, and mix with normal temperature Mix evenly under the ground, add cashew nut oil and an equal amount of water to the mixed material to form an emulsion after vigorously stirring as a plasticizer, and then mix for 5 to 20 minutes, use continuous operation roller pressing method, start the plastic refining machine and its auxiliary equipment The feeding bag is put down, and the temperature of the front roll is set to 90°C. The temperature of the rear roller is set at 145°C, so that the material slowly falls into the feeding end of the roller. When the roller is covered with a layer of material, the coulter can be put down. Send it to the conveyor belt to let it air-cool, and then break it after cooling.

Embodiment 3

[0028] Put 20% of wood powder, 35% of phenolic resin, 8% of Hexa, 3% of magnesium oxide, 1% of slaked lime, 14% of talcum powder, 15% of mica powder, 2% of zinc stearate, and 2% of oil black into the mixing Mix with normal temperature, add cashew nut oil and an equal amount of water to the mixed material to form an emulsion after vigorously stirring as a plasticizer, then mix for 5 to 20 minutes, use continuous operation roller pressing method, start the plastic refining machine and When it is attached to the equipment, the feeding bag is put down, and the temperature of the front roller is set to 100°C. The temperature of the rear roller is set at 155°C, so that the material slowly falls into the feeding end of the roller. When the roller is covered with a layer of material, the coulter can be put down. The material is cut by several coulters and directly from the discharge end Send it to the conveyor belt to let it air-cool, and then break it after cooling.

Abstract

The invention relates to a phenolic molding compound in which the emulsion formed by cashew nut oil and water is used as a plasticizer and a preparation method thereof. Accelerators, lubricants and pigments are put into the mixer in turn and mixed fully and evenly, then the emulsion formed by cashew nut oil and water is added as a plasticizer and mixed for 5-20 minutes, sent to a roller press for plastication, and finally cooled and crushed to produce . Using the emulsion formed by cashew nut oil and water as a plasticizer can improve the material stability of phenolic molding compound under injection molding conditions, increase the fluidity of the material, not affect the curing speed of the material in the mold, and effectively improve the injection molding performance of phenolic molding compound .

Description

technical field [0001] The invention relates to a phenolic molding compound in which the emulsion formed of cashew nut oil and water is used as a plasticizer and a preparation method thereof. Background technique [0002] The raw materials of phenolic molding compound are easy to obtain, the cost is low, and it has the advantages of high mechanical strength and stable performance. However, with the continuous development of society, new requirements are put forward for high-performance phenolic molding compound. Phenolic molding compounds produced with existing plasticizers such as furfural, aniline, ε-caprolactam, p-toluenesulfonamide, etc. are prone to poor thermal stability during injection molding, and sticky molds and black molds occur during molding processing. And problems such as poor appearance of injection parts. Contents of the invention [0003] The object of the present invention is to provide the phenolic molding compound that the emulsion that a kind of ca...
