Problems solved by technology

[0009] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide an antistatic sheet and a preparation method thereof, so as to solve the problem of poor antistatic effect of the plastic sheet produced by the current surfactant-based antistatic agent, and relatively low influence of environmental humidity. Large, poor antistatic durability, easy to contaminate products in contact with it, and the surface resistivity of plastic sheets made of intrinsically conductive or static dissipative polymers is not low enough and the cost is high, and the film made of conductive carbon black The strength and toughness are poor, there is a risk of falling off the charcoal powder and it can only be made into black.

Abstract

The invention discloses an antistatic sheet and preparation method thereof. The antistatic sheet comprises a polyolefin sheet and permanent macromolecule antistatic layers coated on one surface or two surfaces of the polyolefin sheet, and antistatic liquid containing the permanent macromolecule antistatic agents is coated on the surface of the polyolefin sheet and then dried and solidified to form the permanent macromolecule antistatic layers. The antistatic sheet is suitable for mass industrial production, low in cost, durable, effective and good in antistatic effect, low in environment temperature-humidity influence, high in heat-resisting deformation temperature, good in mechanical property and wide in application, and surface electrical resistivity is 105-1010ohm / o.

Description

technical field [0001] The invention relates to the field of antistatic polymer materials and products, in particular to an antistatic sheet and a preparation method thereof. Background technique [0002] PP and PE polyolefin sheets have low density, good temperature resistance, high heat distortion temperature, good chemical compatibility, good tensile strength and wear resistance, balanced hardness and impact resistance, easy to obtain raw materials, and low price. Low and widely used as packaging materials in various industries, but because PP and PE are non-polar polymer materials with high crystallinity and small surface energy, they are good insulators with a surface resistivity of up to 10 14 Ω / □ (ohm / square) or more, it is easy to accumulate static electricity and damage electronic products, and it is easy to absorb dust. It is not suitable for purification and clean workshops, so generally it cannot be directly applied to electronic components and printed circuit bo...
