Problems solved by technology

[0002] Static electricity is an objective natural phenomenon, which can be generated in many ways, such as contact, friction, etc. In equipment with intensive use of polymer materials, the harm caused by static electricity is also obvious, for example, it is easy to cause damage to electronic components inside electronic equipment. The surface of the equipment is easy to absorb dust due to the adsorption effect of static electricity, and it may also cause harm to people who touch the body, thus directly or indirectly bringing electrostatic hazards to the packaging industry, electronics industry, textile industry and other fields
[0003] Most of the sheets in the prior art do not have antistatic properties, and most of them are made of refractory resins or rubbers such as EPDM, neoprene, polyethylene (PE), acrylonitrile-butadiene-benzene Ethylene copolymer (ABS), polyvinyl chloride (PVC), etc. are the main components, processed with plasticizers, fillers, colorants, lubricants and other additives as auxiliary components. Due to their refractory properties, these processed sheets Once used and discarded, it will cause serious "white pollution" and other environmental problems
[0004] The existing transparent sheet not only has poor environmental protection performance, but also does not have anti-static function, which brings inconvenience to the normal use of the sheet and limits the application field of the sheet to a certain extent

Abstract

The invention discloses an antistatic environment-friendly transparent sheet which comprises the following components in parts by weight: 100-150 parts of amorphous polyethylene terephthalate (APET), 10-25 parts of poly(butylene succinate) (PBS), 15-30 parts of heat-resistant modified polylactic acid, 1-3 parts of conduction assistant and 1-3 parts of compatilizer. The invention also discloses a preparation method of the antistatic environment-friendly transparent sheet. The APET is blended with the PBS and heat-resistant modified polylactic acid, and the conduction assistant with favorable blending effect is added to obtain the sheet material with antistatic function, favorable environment friendliness and favorable transparency.
