Embodiment 1

[0030] Will be 15% by weight of HIPS, 48% of GPPS, 15% of PP, 12% of compatibilizer, 10% of inorganic powder (pre-treated with coupling agent), and calculated by their total weight as The 0.5% antioxidant is put into a high-speed mixer with a rotation speed of about 1000rpm and mixed for 3 minutes, and then put into a twin-screw extruder. The temperature is controlled at 200℃~215℃, and the screw speed is 450 rpm. It is obtained by extrusion granulation.

[0031] Synthetic paper extrusion casting processing temperature: 230~250℃

Embodiment 2

[0033] Will be 20% HIPS, 43% GPPS, 22% PP, 5% compatibilizer, 10% inorganic powder (pre-treated with coupling agent) by weight percentage, and 0.5 by their total weight % Antioxidant is first put into a high-speed mixer with a rotation speed of about 1000rpm and mixed for 3 minutes, and then put into a twin-screw extruder, extruded under the conditions of a processing temperature of 200~215℃ and a screw speed of 450 rpm Get the pellets.

Abstract

The invention relates to novel PS (polystyrene) alloy synthetic paper which improves the stiffness, the surface polarity and the surface hardness and resists the chemical corrosion. The paper molded by using an extrusion tape casting method has white appearance and opacity, excellent physical property and superior price, can replace current commonly-used calendered paper, and replaces products of common paper PE (polyethylene) and common paper composite BOPP (biaxially-oriented polypropylene) membranes. The novel PS alloy synthetic paper is applied to common printing materials and processing materials by the characteristics of water prevention and tear resistance, applied to data needing permanent preservation by the characteristic of excellent weather resistance, and adapts to various labels of packages of drink bottles and cans. The invention does not produce the environment pollution during the manufacture and use, can save a great quantity of forest resources and water resources for country, lightens the sewage treatment pressure, and reduces the energy consumption.

Description

Technical field [0001] The invention belongs to the technical field of new synthetic paper materials, and specifically relates to a PS alloy synthetic paper that has improved stiffness, surface polarity and surface hardness and chemical corrosion resistance. Background technique [0002] Synthetic paper is a product made from thermoplastic polymers such as polyethylene, polypropylene, polystyrene, and polyvinyl chloride as the main raw material, adding certain organic or inorganic particles, and through different production equipment and processing techniques. Synthetic paper is divided into PP synthetic paper, HDPE synthetic paper, PS synthetic paper, PVC synthetic paper, PET synthetic paper, ABS synthetic paper, etc. [0003] The synthetic paper production process is mainly based on resin and inorganic filler powder, without consuming forest resources, and more importantly, the two raw materials are non-polluting, and the defective products produced in the manufacturing process c...
