Example Embodiment

[0013] The new type of hollow glass microbead-filled modified plastic is characterized in that it is made of the following parts by weight of raw materials: linear polyethylene 57, high-density polyethylene 42, nano antimony tin oxide 5.3, nano titanium dioxide 0.7, Stearic acid 0.6, potassium persulfate 0.2, isophorone 0.3, hollow glass beads 2, maleic anhydride grafted polypropylene 1, antioxidant 1010 0.03, UV-327 0.04, oxidized polyethylene wax 1, anhydrous A moderate amount of ethanol.

[0014] The production method includes the following steps:

[0015] (1) Calcining nano-tin oxide and nano-titanium dioxide at 585-785°C for 30-50 minutes, cooling and putting them into a three-necked flask, adding absolute ethanol and maleic anhydride grafted polypropylene, stirring evenly, heating to reflux 4 -5h, centrifuged, washed 2~3 times with absolute ethanol, dried in vacuum at 80℃;

[0016] (2) Add stearic acid, oxidized polyethylene wax, and hollow glass beads to the above products, ...

Abstract

The invention discloses a novel hollow glass microballoon filled modified plastic which is prepared from the following raw materials in parts by weight: 50-60 parts of linear polyethylene, 35-45 parts of high-density polyethylene, 4.3-6.2 parts of nano antimony tin oxide, 0.6-1.4 parts of nano titanium white, 0.5-0.8 part of stearic acid, 0.1-0.3 part of potassium persulfate, 0.2-0.4 part of isophorone, 2-3 parts of hollow glass microballoon, 1-2 parts of maleic anhydride grafted polypropylene, 0.02-0.04 part of antioxidant 1010, 0.02-0.04 part of UV-327, 1-3 parts of oxidized polyethylene wax and a right amount of anhydrous ethanol. The manufacturing method comprises the following steps: adding the nano materials into the coupling agent, uniformly mixing with the linear polyethylene, high-density polyethylene, hollow glass microballoon, isophorone and the like, and carrying out melt extrusion granulation with a double screw extruder. The prepared plastic has the advantages of favorable ultraviolet cracking resistance, favorable mold resistance, favorable heat resistance, higher tensile strength and higher shock strength.

Description

technical field [0001] The invention relates to the technical field of plastic modification, in particular to a novel modified plastic filled with hollow glass microspheres and a production 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-purpose ...
