Embodiment 1

[0023] Input wood powder 30%, thermoplastic phenolic resin 40%, Hexa 6.5%, calcium carbonate 8%, talcum powder 4%, magnesium oxide 2.5%, slaked lime 0.5%, calcium stearate 1.5%, titanium blue 2%, Put 3.5% of titanium dioxide and 1.5% of polyethylene glycol into the mixer in turn, and mix thoroughly at room temperature for 30 minutes. Using the intermittent operation method, start the roller press and its auxiliary equipment, and slowly drop the fully mixed mixture into the roller. In the middle of the rollers of the press, the temperature of the front rollers was set at 85°C. The temperature of the rear roller is set to 140°C, and when a layer of material of about 2.4mm is covered with the roller, the electric scraper is turned on for cutting. First cut about 3 kg as the primer, and at the same time, the feeding bin will slowly add the material into the middle of the roller until the entire roller is covered with the material, and no longer add the mixed material; at this time...

Embodiment 2

[0025] Add 30% bamboo powder, 45% thermoplastic phenolic resin, 6% Hexa, 6% calcium carbonate, 3% talcum powder, 2% magnesium oxide, 0.5% slaked lime, 2% zinc stearate, 1.5% titanium blue, Put 3% of titanium dioxide and 1% of ethylene glycol into the mixer in turn. After fully mixing at room temperature for 45 minutes, use the intermittent operation method to start the roller press and its auxiliary equipment, and slowly drop the fully mixed mixture into the roller. In the middle of the rollers of the press, the temperature of the front rollers was set at 90°C. The temperature of the rear roller is set to 145°C, and when a layer of material of about 2mm is covered with the roller, the electric scraper is turned on for cutting. First cut about 4 kg as the primer, and at the same time, the feeding bin will slowly add the material to the middle of the roller until the entire roller is covered with the material, and no longer add the mixed material; at this time, the material shou...

Embodiment 3

[0027] Put in 32% wood powder and bamboo powder mixture, 42% thermoplastic phenolic resin, 6% Hexa, 7% calcium carbonate, 2% talcum powder, 3% magnesium oxide, 0.5% slaked lime, 1.5% zinc stearate, titanium blue Blue 1.8%, titanium dioxide 3.2%, and ethylene glycol 1% were put into the mixer in turn, and after fully mixing at room temperature for 60 minutes, the batch operation method was adopted to start the roller press and its auxiliary equipment, and the fully mixed mixture Slowly fall into the middle of the roller of the roller press, and the temperature of the front roller is set to 100°C. The temperature of the rear roller is set to 150°C, and when a layer of material of about 2.5mm is covered on the belt roller, the electric scraper is turned on for cutting. First cut about 3 kg as the primer, and at the same time, the feeding bin will slowly add the material into the middle of the roller until the entire roller is covered with the material, and no longer add the mixed...

Abstract

The invention relates to a blue phenolic moulding plastic and a preparation method thereof, the blue phenolic moulding plastic is prepared by sufficiently and evenly mixing organic reinforcing material, thermoplastic phenolic resin, curing agent, lubricating agent, inorganic filler, plasticizing agent and pigment, feeding the mixture into a roller press for plastication, and cooling and crushing the mixture. The phenolic moulding plastic not only has excellent light fastness and heat resistance, good aging resistance, dazzling color and little possibility of decolorization, but is also outstanding in injection molding performance and high in bending strength.

Description

technical field [0001] The invention relates to a blue phenolic molding compound and a production method thereof. Background technique [0002] At present, in order to beautify the appearance of bakelite products, it is usually necessary to spray paint the bakelite products, which undoubtedly greatly increases the production cost. Phenolic molding compound, also known as bakelite powder and bakelite powder, has good insulation properties and is mainly used in the manufacture of daily necessities, low-voltage electrical appliances, insulating structural parts and mechanical parts of instruments. If phenolic molding compound is used to directly inject bakelite products, then The above problems can be solved. Contents of the invention [0003] The object of the present invention is to provide a kind of blue phenolic molding compound. The phenolic molding compound made with the formula of the present invention not only has good aging resistance, bright color and is not easy t...
