Problems solved by technology

[0004] However, in the prior art, the PC material will be further dried before injection molding, but because the moisture completely penetrates into the inside of the PC material, the traditional hot air dryer cannot completely dry it. A dehumidifier with a honeycomb filter structure will be used for drying. Since the thickness of the honeycomb plate is greater, the flow resistance to the airflow is higher. When the PC material is dried in the early stage, the moisture in the gas is higher, and the dehumidification required at this time The higher the temperature is, the moisture content in the gas will decrease in the later stage of drying. At this time, the thicker honeycomb plate will affect the circulation efficiency of the airflow instead.

preparation example Construction

[0036] A preparation method of a wear-resistant and flame-retardant PC material, which is suitable for the formulation of the above-mentioned wear-resistant and flame-retardant PC material, comprising the following preparation steps:

[0037] S1: First, weigh PC material, antioxidant, heat stabilizer, bright lubricant, phase solvent, flame retardant, hydroxyl silicone oil, silicone and matrix resin according to the proportion requirements;

[0038] S2: Then first add the PC material into the dehumidifier, and dehumidify the gas derived from the PC material through the honeycomb plate 3 inside the dehumidifier, so that the moisture derived from the PC material condenses on the surface of the honeycomb plate 3, and then pass through the dehumidifier. Introduce hot gas to the guide to quickly remove the water inside the honeycomb plate 3;

[0039] S3: Add the dehumidified PC material into the heating and stirring machine, and then add antioxidants, heat stabilizers, bright lubric...

Abstract

The invention relates to the field of plastic formulas, and concretely relates to a formula, a preparation method and a production device of a wear-resistant flame-retardant PC material. The production device comprises a motor seat, a motor and honeycomb plates; guide plates are fixedly connected to the side surfaces of the honeycomb plates; control grooves are uniformly formed in the surface of the guide plate; the interiors of the control grooves are in sliding connection with control plates; first springs are fixedly connected between the control plates and the bottoms of the corresponding control grooves; first guide holes are formed in the surfaces of the guide plates; and second guide holes are formed in the surfaces of the control plates. According to the invention, the cooperative use of a plurality of honeycomb plates is effectively realized, the air can be controlled to flow through the honeycomb plates by controlling the opening and closing of the guide plates, the control of the use number of the honeycomb plates is realized, the sufficient dehumidification of the circulating air in the early stage is ensured, the use number of the honeycomb plates in the later use stage is reduced, the resistance to air circulation is reduced, and the dehumidification efficiency is improved.

Description

technical field [0001] The invention relates to the field of plastic formulations, in particular to a formulation, a preparation method and a production device of a wear-resistant and flame-retardant PC material. Background technique [0002] Due to the strong hygroscopicity of the PC material, during the processing of the PC material, if the PC material is not fully dried, the injection molding production is performed directly, and the product is prone to shrinkage, silver streaks, bubbles, cracks, marks, and poor transparency. And so on. [0003] According to CN107805380A, a formulation of wear-resistant PC material, the present invention is a formulation of PC and ABS mixed plastic, which makes the prepared PC and ABS mixed plastic have permanent conductivity, anti-aging, anti-static, high toughness, fusion Wait for the effect. [0004] However, in the prior art, the PC material will be further dried before injection molding, but because the moisture completely penetrat...
