Embodiment 1

[0028] Weigh 80 parts of CPVC, 10 parts of ABS, 1 part of sodium antimonate, 5 parts of calcium stearate and 0.5 part of polyethylene wax, put the above materials into a high-speed mixer and mix them evenly; Mixing was carried out in the mill for 2 minutes, and the temperature of the two-roll mill was 180°C. Put the kneaded material in a flat vulcanizing machine, press molding for 10 minutes under the conditions of a template temperature of 190° C. and a pressure of 10 MPa, and cold pressing for 5 minutes. The sample strips were prepared according to the ISO standard with a sample preparation machine, and tested according to the standard after being placed under the conditions of a constant temperature of 23 ° C and a humidity of 50% for 48 hours. The test results are shown in Table 1.

Embodiment 2

[0030] Weigh 40 parts of CPVC, 50 parts of ABS, 10 parts of sodium antimonate, 0.5 parts of barium stearate and 3 parts of polyethylene wax, put the above materials into a high-speed mixer and mix them evenly; Mixing was carried out in the mill for 6 minutes, and the temperature of the two-roll mill was set at 185°C. Put the kneaded material in a flat vulcanizing machine, press molding for 12 minutes under the conditions of a template temperature of 195° C. and a pressure of 15 MPa, and cold pressing for 8 minutes. The sample strips were prepared according to the ISO standard with a sample preparation machine, and tested according to the standard after being placed under the conditions of a constant temperature of 23 ° C and a humidity of 50% for 48 hours. The test results are shown in Table 1.

Embodiment 3

[0032] Weigh 60 parts of CPVC, 30 parts of ABS, 5 parts of antimony trioxide, 3 parts of zinc stearate and 2 parts of polyethylene wax, put the above materials into a high-speed mixer and mix them evenly; Mixing was carried out in the open mill for 5 minutes, and the temperature of the two-roll open mill was set at 185°C. Put the kneaded material in a flat vulcanizing machine, press molding for 8 minutes under the conditions of a template temperature of 195° C. and a pressure of 12 MPa, and cold pressing for 10 minutes. The sample strips were prepared according to the ISO standard with a sample preparation machine, and tested according to the standard after being placed under the conditions of a constant temperature of 23 ° C and a humidity of 50% for 48 hours. The test results are shown in Table 1.

Abstract

The invention discloses a flame retardant CPVC-ABS (Chlorinated Polyvinyl Chloride-Acrylonitrile Butadiene Styrene) alloy material which is prepared from the components in parts by weight: 40-80 parts of CPVC, 10-50 parts of ABS, 1-10 parts of a flame retardant and 1-8 parts of a processing agent. The invention further discloses a preparation method of the flame retardant CPVC-ABS alloy material. Compared with the prior art, CPVC in the alloy material disclosed by the invention combusts to generate HCl which can shield and dilute combustible gases. Antimonous oxide or (and) sodium antimonite in the initial combustion period is fused on the surface of the material to form a protective film to isolate air. In a high temperature state, antimonous oxide or (and) sodium antimonite is gasified to dilute oxygen concentration in air and is commonly used with CPVC to generate SbOCl and SbCl3, so as to have the flame retardant effect. The alloy material is less in use level and good in flame retardant effect.

Description

technical field [0001] The invention relates to a polymer material, in particular to a flame-retardant CPVC-ABS alloy material and a preparation method thereof. Background technique [0002] Chlorinated polyvinyl chloride (CPVC) is an important modified variety of polyvinyl chloride (PVC). The chlorine content in CPVC resin molecules is generally 61% to 68%, and the theoretical content can reach 73.2%. Since more chlorine atoms are contained in the CPVC molecule, the rigidity of the molecular chain is enhanced, so that the glass transition temperature and heat distortion temperature of the CPVC resin are higher, so the heat resistance and the highest service temperature are significantly higher than that of the PVC resin. CPVC resin also has excellent mechanical properties, non-conductivity, chemical resistance, good flame retardancy and low smoke generation. [0003] CPVC and ABS (abbreviation for acrylonitrile-styrene-butadiene copolymer) blend materials not only have th...
