Embodiment approach 1

[0031] Embodiment 1: Put 50% of inorganic powder, 30% of carrier resin, 5% of toughening agent, 3% of dispersant, 5% of lubricant, 5% of coupling agent, and 3% of stabilizer into the mixer Stir in the middle, and the temperature reaches 110°C to make a mixture; put the mixture into a twin-screw extruder for extrusion, cut the die surface into pellets, and obtain a composite blow molding material.

Embodiment approach 2

[0032] Embodiment 2: Put 70% of inorganic powder, 20% of carrier resin, 3% of toughening agent, 3% of dispersant, 2% of lubricant, 1% of coupling agent, and 1% of stabilizer into the mixer Stir in the middle, and the temperature reaches 130°C to make a mixture; put the mixture into a twin-screw extruder to extrude, cut the mold surface eagerly, and cut into pellets to obtain a composite blow molding material.

Embodiment approach 3

[0033] Embodiment 3: Put 60% of inorganic powder, 28% of carrier resin, 2% of toughening agent, 1% of dispersant, 4% of lubricant, 3% of coupling agent, and 2% of stabilizer into the mixer Stir in the middle, and the temperature reaches 150°C to make a mixture; put the mixture into a twin-screw extruder for extrusion, cut the mold surface eagerly, and cut into pellets to obtain a composite blow molding material.

Abstract

The invention relates to the field of processing of macromolecular compounds, in particular to a film blowing material and a preparation method thereof. The material special for blowing a packaging film comprises a composite blowing material, wherein the composite blowing material comprises carrier resin, inorganic powder, a toughening agent, a dispersing agent, a lubricating agent, a coupling agent and a stabilizer. The preparation method for the material special for blowing the packaging film comprises the following steps of: 1) mixing the composite blowing material; and 2) performing extrusion granulation on the mixture. Through the technical scheme, the composite blowing material has the obvious advantages that cost is low, dispersion points do not exist on the surface of a film-coated product, and the like.

Description

technical field [0001] The invention relates to the field of polymer compound processing, in particular to a blown film material and a manufacturing method. Background technique [0002] Traditional shopping bags or packaging films are generally prepared by blending and blow molding of polyolefin resin and a small amount of filler material prepared by inorganic powder. Traditional shopping bags or packaging films are relatively complicated in technology and need to be formulated strictly according to a certain ratio. And in the preparation process, a special stirring link is required for stirring. In addition, the amount of filler material added is relatively small, and the general amount added does not exceed 30% of the total amount of blow molding materials, so the effect of cost reduction is not obvious. Contents of the invention [0003] The object of the present invention is to provide a special material for blown film for packaging to solve the above technical prob...
