Abstract

The invention discloses a composite filling particle for preparing a high-strength light-colored non-woven fabric and a preparation method thereof and an application field thereof. The composite filling particle is composed of the following raw materials by weight: 100 parts of biomass calcium carbonate shell powder, 1-5 parts of acicular wollastonite, 1 to 5 parts of chopped carbon fiber, 1 to 2parts of rutile type titanium dioxide, 10 to 25 parts of polypropylene, 0.1 to 0.5 parts of stearic acid, 0.2 to 0.5 part of a silane coupling agent and 0.5 to 2 parts of PE wax; the preparation method is as follows: first preparing dispersed powder A, then preparing modified powder B, and finally using a single-screw-assisted twin-screw plasticization process for extruding and granulating the polypropylene and the PE wax. The composite filling particle has excellent application performance, and a prepared end product non-woven fabric has high tensile strength and can be used in the field of an industrial or civil packaging material, a filter material and the like.

Description

technical field [0001] The invention belongs to the processing of organic and inorganic composite materials and the corresponding application fields, and specifically relates to a composite filling particle for preparing high-strength non-woven fabrics, a preparation method and application thereof. Background technique [0002] At present, environmental protection and efficient utilization of resources are two hot issues in front of people. Green environmental protection concepts such as energy saving and consumption reduction have gradually penetrated into people's daily production and life. Environmental protection such as "five water systems" and "air purification" Measures have gradually been put on the relevant agenda. As far as the traditional plastic industry is concerned, in view of the fact that traditional plastics are difficult to degrade, the problem of "white pollution" produced by it has brought immeasurable negative impacts on the ecological environment. On t...
