Boron fiber modified plastic and preparation method thereof

Abstract

The invention discloses boron fiber modified plastic, which is prepared from the following raw materials in parts by weight: 50-60 parts of high-density polyethylene, 25-35 parts of styrene, 10-14 parts of polyimide, 4.7-7.5 parts of nano antimony tin oxide, 1-2 parts of nanometer titanium dioxide, 2-4 parts of lauryl acrylate, 0.6-1.4 parts of Tween 20, 2-3 parts of ash-calcium-powder, 0.3-0.6 part of magnesium sulfate, 3-5 parts of gelatin, 1.2-2.2 parts of boron fiber, 0.5-0.8 part of aminopropyltriethoxysilane and a proper amount of absolute ethyl alcohol. The method comprises the following steps: firstly, adding a nano material to a coupling agent, stirring and activating, and mixing with high-density polyethylene, styrene, polyimide, boron fiber and the like evenly; and fusing, extruding and pelletizing through a twin-screw extruder. The prepared plastic is good in acid and alkali resistance, high in strength, and high in rigidity; and the tensile strength and the impact strength are significantly improved.

Description

technical field [0001] The invention relates to the technical field of plastic modification, in particular to a boron fiber modified plastic 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-purpose plastics and engineering plas...
