Embodiment 1

[0026] The preparation method of the above-mentioned foamed polyolefin antistatic material comprises the following steps: (1) immersing the foamed polyolefin base material in an antistatic liquid mixed with water with a mass fraction of 1%, a pH of 7.0, and a temperature of In the solution at 20°C, so that the solution is absorbed and coated on the substrate, the antistatic liquid is a commercially available antistatic liquid; (2) Preliminarily filter and dry until the substrate hangs and does not drip; (3 ) using a group of pressure rollers with a flexible surface to squeeze the preliminarily filtered and dried substrate coated with the antistatic liquid, and the extrusion force is 0.1N, so that the antistatic liquid is inside the substrate and The surface is evenly distributed; (4) corona treatment on the surface of the substrate. The product is obtained.

Embodiment 2

[0028] A method for preparing a foamed polyolefin antistatic material, comprising the following steps: (1) soaking the foamed polyolefin base material in an antistatic solution mixed with water with a mass fraction of 2%, a pH of 7.5, and a temperature of 25 ℃ solution, so that the solution is absorbed and coated on the substrate, and the antistatic solution is a commercially available antistatic solution; (3) a set of pressure rollers with a flexible surface is used to absorb and coat the preliminary filter. The substrate of the antistatic liquid is extruded, and the extrusion force is 3N, so that the antistatic liquid is evenly distributed inside and on the surface of the substrate; (4) Corona treatment is performed on the surface of the substrate. The product is obtained.

Embodiment 3

[0030] The preparation method of the above-mentioned foamed polyolefin antistatic material comprises the following steps: (1) immersing the foamed polyolefin base material in an antistatic liquid mixed with water with a mass fraction of 3%, a pH of 7.3, and a temperature of In the solution at 23°C, so that the solution is absorbed and coated on the substrate, the antistatic liquid is a commercially available antistatic liquid; (2) Preliminarily filter and dry until the substrate hangs and does not drip; (3 ) using a group of pressure rollers with flexible surfaces to squeeze the preliminarily drained base material coated with the antistatic liquid, and the extrusion force is 5N, so that the antistatic liquid is inside and on the surface of the base material Uniform distribution; (4) Corona treatment on the surface of the substrate. The product is obtained.

Abstract

The invention relates to the field of high polymer materials and in particular relates to a foaming polyolefin anti-static material and a preparation method thereof. The material has the surface resistance of 10 <7-10> ohm, and comprises a foaming polyolefin base material and also comprises an anti-static fluid which exerts an anti-static effect and is sucked to the foaming polyolefin base material; an anti-static layer is formed by the anti-static fluid on the surface of the base material; the thickness of the anti-static layer is 0.1-1 micrometer. The preparation method comprises the following steps: (1) soaking the foaming polyolefin base material in a 1-5 mass percent of solution formed by adding water into the anti-static fluid, so that the solution is sucked to the base material; (2) performing primary draining; (3) allowing the anti-static fluid to be uniformly distributed inside and on the surface of the base material; (4) performing corona treatment on the surface of the base material. The obtained foaming polyolefin anti-static material is good and stable in physical performance and obvious in anti-static effect. The method for preparing the material is easy to operate and can be used for industrial production, the cost is reduced, and the environment is protected.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a foamed polyolefin antistatic material and a preparation method thereof. Background technique [0002] The foamed polyolefin material is a new type of material, which uses polyethylene, polypropylene or ethylene as the basic component and contains a large number of bubbles, so the foamed polyolefin material can also be said to be a composite material filled with gas. There are many varieties, but because they all contain a large number of air bubbles, they have common characteristics, such as light weight, material saving, low thermal conductivity, good heat insulation performance, ability to absorb impact loads, excellent cushioning performance, good sound insulation performance, and specific strength. Advanced good performance. However, this kind of foam material has relatively poor antistatic property, which makes it have defects in the application of chemical pipelines and ...
