specific Embodiment approach

[0023] Step 1, by weight, add 50-80 parts of PC, 10-40 parts of PET, 3-10 parts of minerals, 1-3 parts of compatibilizer, and 0.2-1 part of antioxidant into the extruder to form homogeneous mixture;

[0024] Step 2: Adjust the temperature of the extruder to 240-270°C, transform the mixture obtained in Step 1 into a molten state, knead and extrude the mixture, and perform granulation to obtain the heat-resistant and solvent-resistant PC / PET modified resin .

Embodiment approach 1

[0026] Add PC, PET, minerals, compatibilizers, and antioxidants to the mixer to disperse evenly, then add the mixture to the extruder, adjust the temperature of the extruder to 240-270°C, and convert the mixture into a molten state. The mixture is kneaded and extruded, and granulated to obtain a heat-resistant and solvent-resistant PC / PET modified resin.

Abstract

The invention discloses a heat-resistant and solvent-resistant PC / PET modified resin material. The heat-resistant and solvent-resistant PC / PET modified resin material is prepared by the following steps: adding 50 to 80 parts of PC, 10 to 40 parts of PET, 3 to 10 parts of mineral, 1 to 3 parts of a compatilizer and 0.2 to 1 part of an antioxidant into a stirring machine, dispersing uniformly, adding the mixture into an extruding machine, adjusting the temperature of the extruding machine to be 240 to 270 DEG C to convert the mixture into a melting state, mixing and extruding the mixture, and pelleting to obtain heat-resistant and solvent-resistant PC / PET modified granules. The heat-resistant and solvent-resistant PC / PET modified resin provided by the invention can be subjected to injection molding according to the flowability requirement, samples are prepared by extruding sheet materials or blowing molding and suction molding, and the material cost is reduced under the condition of guaranteeing various properties.

Description

technical field [0001] The invention belongs to the field of polyurethane composition manufacture, and in particular relates to a heat-resistant and solvent-resistant PC / PET modified resin. Background technique [0002] PC / PET has both the rigidity and heat resistance of PC (polycarbonate) and the corrosion resistance of PET (polyethylene terephthalate). Moreover, the addition of PET improves the processing fluidity of PC. PC / PET has excellent properties that single components do not have, and can be used in many occasions. It is of great significance for saving energy, effectively using petroleum resources, and protecting the environment. The research of PC / PET alloy broadens the application fields of PET on the one hand, and improves the added value of PET on the other hand. However, PC is not resistant to solvents and PET is sensitive to heat, so there are certain limitations in the use of PC / PET alloy materials, and it is urgent to improve the heat resistance and solven...
