preparation example Construction

[0030] The preparation method of antistatic biodegradable foam material of the present invention, the steps are as follows:

[0031] Step 1. Weigh each raw material according to the composition and parts by weight, and add it to a twin-screw extruder for mixing and granulation. The mixing and granulation temperature is 80-170°C. Extrude the sheet on the machine, the thickness of the sheet is 0.5-3.0mm, preferably 1mm, and the extrusion temperature is 100-170°C;

[0032] Step 2, in the air at room temperature, use an electron accelerator or cobalt ( 60 Co) source ionizing radiation irradiates the blend sheet with ionizing radiation at a dose of 2-100KGy, preferably 80-90KGy, to obtain a crosslinked material;

[0033] Alternatively, in the air at room temperature, ionizing radiation is performed on the sheet obtained in step 1, and the irradiation dose is 0.5-9KGy to obtain a pre-crosslinked material; the pre-crosslinked material is further processed in a hot water bath at 50-8...

Abstract

The invention relates to an antistatic biodegradable foaming material and a preparation method thereof and belongs to the technical field of foaming material, which solves the problem of declining ofmechanical property of material due to adding a large ratio of antistatic agent when the method of the antistatic property of the poly(p-butyleneadipate-co-terephthalate) foaming material needed to beimproved in the prior art. The antistatic biodegradable foaming material is prepared from the following components in parts by weight: 60 to 100 parts of poly(p-butyleneadipate-co-terephthalate), 0 to 40 parts of biodegradable polymer, 1 to 15 parts of antistatic agent, 1 to 5 parts of inorganic filler, 0.5 to 15 parts of foaming agent, 0.01 to 5 parts of foaming additive, and 0.1 to 5 parts of crosslinking agent. The antistatic biodegradable foaming material has the advantages that the antistatic property is excellent, the physical property is excellent, the water-resistant property is good,the durability is good, the foaming rate is higher, and the mechanical property can be regulated in the wide range.

Description

technical field [0001] The invention relates to an antistatic biodegradable foam material and a preparation method thereof, belonging to the technical field of foam materials. Background technique [0002] Whether it is made of polyethylene, polystyrene, or polyurethane, it has light weight, material saving, low thermal conductivity, good heat insulation performance, shock load absorption, good sound insulation performance, and high specific strength. , Play a huge role in the packaging industry. However, after these foam plastics are used, it is difficult to recycle them for recycling, and they are discarded into the environment, which cannot be assimilated with the environment, causing great harm to the environment. If it floats in the ocean and is swallowed by marine organisms, it will cause the death of marine organisms. Therefore, vigorously developing and promoting degradable foam materials has attracted the attention of academic and industrial circles worldwide. ...
