UV-resistant anti-crack modified plastic and production method thereof

Abstract

The invention discloses a type of UV-resistant anti-crack modified plastic. The UV-resistant anti-crack modified plastic comprises, by weight, 50 parts to 60 parts of polyethylene, 30 parts to 40 parts of EVA resin, 5 parts to 8 parts of nanometer tin antimony oxide, 1 part to 3 parts of nanometer titanium dioxide, 2 parts to 4 parts of China hemp fiber powder, 1.1 parts to 2.3 parts of zinc stearate, 1 part to 2 parts of nanometer organic montmorillonite, 0.2 part to 0.4 part of antimony oxide, 0.1 part to 0.3 part of 2-Dihydroxy-4-methoxybenzophenone, 0.5 part to 1.2 parts of polydimethylsiloxane, and the appropriate amount of absolute ethyl alcohol. The produced plastic is resistant to UV light and cracking, is remarkably improved in tensile strength and impact strength, and is improved to some extent in chemical resistance and heat resistance; when the plastic is deeply processed to form film which is used for vegetable greenhouses, the plastic has the advantages of being high in low temperature resistance, obvious in heat insulation, self-cleaning, antibacterial, high in light transmittance and the like.

Description

technical field [0001] The invention relates to the technical field of plastic modification, in particular to a modified plastic resistant to ultraviolet light and cracking and a manufacturing method thereof. Background technique [0002] Our country has a vast territory and a complex climate. The use of plastic greenhouses for vegetable cultivation has played a special and important role in alleviating the contradiction between supply and demand of vegetables in the off-season. It has significant social benefits and huge economic benefits. Special plastic greenhouses for agricultural production and construction It is required that its light transmittance, heat preservation, tensile strength and aging resistance are superior to ordinary agricultural films. The existing technology cannot meet these requirements, and traditional plastics need to be modified to obtain modified plastics. Modified plastics refer to plastic products that are processed on the basis of general-purpo...
