Embodiment 1——4

[0011] 1. Prepare high-impact polystyrene material (HIPS), base color masterbatch, and flow pattern masterbatch according to the proportions, and mix them with a low-speed mixer as the surface material raw materials. The material formula is shown in Table 1 (1 part by weight 1 kg)

[0012] Table I

[0013]

[0014] 2. Combine 100 parts of polystyrene material, 2 parts of foaming agent, 1 part of color masterbatch (Example 1-2 uses yellow color masterbatch, Example 3-4 uses white color masterbatch), 2 parts plasticizer , Add a high-speed mixer and mix evenly as the core material.

[0015] Among them, the foaming agent can use the AK-8 foaming agent of Hangzhou Dingyue Chemical Co., Ltd.;

[0016] Color masterbatch can use H series masterbatch of New Particle Chemical Pigment Co., Ltd.;

[0017] As the plasticizer, dioctyl phthalate can be used.

[0018] The core layer polystyrene material can use recycled polystyrene material.

[0019] Co-extrusion molding: The processing equipment inclu...

Abstract

The invention relates to a preparation method of polystyrene micro-foaming co-extrusion imitation wood material. It is characterized in that: prepare the surface layer material and the core layer material, put the surface layer material and the core layer material into the auxiliary extruder and the main extruder respectively, the two extruders are co-extruded into a mold, and are fused in the mold One body, in which the surface layer material is coated on the surface of the core layer material. The base material of the surface material is high-impact polystyrene and it contains rhyolite masterbatch that is compatible with high-impact polystyrene but has different fluidity and dispersion. The core material is polystyrene micro-foaming material. The weight ratio of the core layer material to the surface layer material is 85-95%: 5-15%. The present invention can produce a variety of products with different effects according to the difference in color and weight of the primary color masterbatch and flowline masterbatch added to the surface material, the difference in the type of flowline masterbatch, and the difference in processing technology. Such as various imitation wood grain products, products of various designs and colors, etc.

Description

Technical field [0001] The invention relates to a polystyrene micro-foaming co-extrusion method. Specifically, it relates to a polystyrene micro-foamed co-extruded wood-like material and a preparation method thereof. Background technique [0002] Polystyrene imitation wood profiles have a series of advantages such as light weight, low price, insect resistance, moth resistance, moisture resistance, non-toxic and environmental protection, and long service life. Widely used in photo frames, picture frames, home decoration materials and other places. At present, the process of imitation wood grain in the production process of polystyrene imitation wood material mainly includes the following: 1. Use stickers to print various patterns on the surface of the polystyrene extrusion material; 2. In the polystyrene extrusion material Spray paint on the surface to make various patterns; 3. Cover the surface of the polystyrene extruded material with gypsum, and then spray paint to make vario...
