Problems solved by technology

However, its synthesis reaction is mainly carried out in the emulsion, and a large amount of waste water will be generated during production, which does not conform to the concept of green environmental protection.
And the product performance is single. When MABS is more and more widely used in home appliances, flame retardancy has become an essential feature requirement.

Embodiment 1

[0030] The following raw materials are prepared: 55 parts of MABS, 45 parts of polyurethane elastomer (two kinds of composite polyurethane elastomers with an average particle size of 70nm and 400nm mixed in a mass ratio of 1:1), 5 parts of triphenyl phosphate, 0.25 part of pentaerythritol hard Fatty acid ester, 0.2 part UV-531, 0.15 part Antioxidant 1010 and 0.15 part Antioxidant 168.

[0031] Blend the polyurethane elastomer and MABS (the difference between the refractive index of the polyurethane elastomer and the MABS matrix is ​​0.005, and the elongation at break of the polyurethane elastomer is 320%), and add triphenyl phosphate, pentaerythritol stearate, UV -531, Antioxidant 1010 and Antioxidant 168. Extruded in a twin-screw extruder with a temperature of 210° C. and a rotational speed of 200 rpm to finally obtain the high-transparency and high-impact flame-retardant MABS composite material.

Embodiment 2

[0033] The following raw materials are prepared: 85 parts of MABS, 15 parts of polyurethane elastomer (two kinds of composite polyurethane elastomers with an average particle size of 70nm and 500nm mixed in a mass ratio of 1:1), 15 parts of triphenyl phosphate, 0.15 parts of pentaerythritol hard Fatty acid ester, 0.5 part UV-531, 0.25 part Antioxidant 1010 and 0.25 part Antioxidant 168.

[0034] Blend the polyurethane elastomer and MABS (the difference between the refractive index of the polyurethane elastomer and the MABS matrix is ​​0.008, and the elongation at break of the polyurethane elastomer is 310%), and add triphenyl phosphate, pentaerythritol stearate, UV -531, Antioxidant 1010 and Antioxidant 168. Extruded in a twin-screw extruder with a temperature of 240° C. and a rotational speed of 250 rpm to finally obtain the high-transparency and high-impact flame-retardant MABS composite material.

Embodiment 3

[0036] The following raw materials were prepared: 85 parts of MABS, 15 parts of polyurethane elastomer (two kinds of composite polyurethane elastomers with an average particle size of 50nm and 400nm mixed in a mass ratio of 1:1), 25 parts of triphenyl phosphate, 0.15 parts of pentaerythritol hard Fatty acid ester, 0.5 part UV-531, 0.25 part Antioxidant 1010 and 0.25 part Antioxidant 168.

[0037] Blend the polyurethane elastomer and MABS (the difference between the refractive index of the polyurethane elastomer and the MABS matrix is ​​0.005, and the elongation at break of the polyurethane elastomer is 300%), and add triphenyl phosphate, pentaerythritol stearate, UV -531, Antioxidant 1010 and Antioxidant 168. Extruded in a twin-screw extruder with a temperature of 180° C. and a rotational speed of 200 rpm to finally obtain the high-transparency and high-impact flame-retardant MABS composite material.

Abstract

The invention belongs to the field of polymer materials, and in particular relates to a highly transparent and high-impact flame-retardant MABS composite material and a preparation method thereof. In the present invention, two kinds of polyurethane elastomers with different particle sizes are prepared by using polyether polyol and isocyanate, and the flame-retardant MABS composite material composition prepared by mixing with MABS has a light transmittance of 70-95%, and an impact strength of 20-40KJ / m 2 , the flame retardant grade can reach UL94V-2 grade or above; the preparation raw materials are simple and easy to obtain, the preparation steps are few, the efficiency is high, and it is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a high-transparency and high-impact flame-retardant MABS composite material and a preparation method thereof. Background technique [0002] ABS resin is a terpolymer composed of acrylonitrile, butadiene and styrene, which has excellent processing properties, high gloss and excellent electroplating properties. With the improvement of living standards, people put forward higher requirements for the beauty of materials, and the transparent ABS resin-MABS came into being. However, MABS on the market generally has low impact toughness and is flammable, which is limited in the application of electronic appliances and automotive exterior parts. However, when the ordinary modification method is modified, it is easy to reduce the transparency or even become opaque, or only give it a certain characteristic. Therefore, it is urgent to develop a kind of flame-retardant MABS wit...
