Composition % according to the following material parts by mass

[0059] (1) Formulation:

[0060] ①After collection, purification, crushing or modification, the waste returns to polyethylene plastic 45.0;

[0061] ② Dried or ground, modified wood fiber or sawdust 17.0;

[0062] ③Chitin fiber fine powder 12.0;

[0063] ④ medical stone nano powder 7.0;

[0064] ⑤ Odd ice stone nano powder 8.0;

[0065] ⑥Antioxidant CA 0.2;

[0066] ⑦Auxiliary antioxid...

Embodiment 2

[0077] Example 2: Composite multifunctional waste polyethylene flame retardant chitin wood fiber sheet is composed of the following material parts by mass

[0078] A recipe:

[0079] (1) Waste polyethylene HDPE pellets 51.0;

[0080] (2) Sawdust or wood fiber 20.0;

[0081] (3) chitin viscose fiber 10.0;

[0082] (4) medical stone nano powder 4.0;

[0083] (5) Tourmaline Nano Powder 5.0;

[0084] (6) Permanent flame retardant 4.0;

[0085] (7) Antioxidant CA 0.2;

[0086] (8) Auxiliary antioxidant DSTP 0.2;

[0087] (9) Internal lubricant 3.0;

[0088] (10) External lubricant 0.6;

[0089] (11) Crosslinker DCP 2.0.

[0090] Preparation:

[0091] Because waste polyethylene HDPE refers to the combination of high-density waste polyethylene and wood fiber to produce artificial wood, due to the poor compatibility between waste high-density polyethylene and wood fiber, it is necessary to add an appropriate coupling agent or use activated wood fiber, and then...

Abstract

The invention discloses a composite multifunctional polyethylene flame retardant chitin wooden fiber plastic floor sheet material, which belongs to the technology field of plastic floor sheet material production by adding enhanced modifiers and tackifiers, etc. into plastic waste and wood chips. The invention mainly solves the technical problem of environmental pollution caused by plastic waste and wood chips in mankind household garbage, changes waste into valuables for recovery and utilization, and saves resources. The key point of the technical scheme is that the sheet material is prepared by adding chitin or chitosan viscose fiber, Chinese medical stone, tourmalinite, coral fossil nanometer powder, a permanent fire retardant SCJ-9689, a modifier, a cross-linking agent and a tackifier, etc. in the plastic waste and the wood chips for fusion and calendaring. The sheet material in the invention can release trace elements, radiate far-infrared light, and spontaneously generate negative ions that are beneficial to human body health , has the functions of antibiosis, sterilization, flame retardation and biodegradation, and is widely used for decoration of indoor floor, separator plates and ceilings.

Description

Technical field: [0001] The composite multifunctional polyethylene flame-retardant chitin wood fiber plastic floor sheet of the invention belongs to the technical field of formula design and production of plastic floor sheet for recycling waste plastics and scrap wood chips. Background technique: [0002] Waste plastics in people's domestic garbage, such as disposable plastic packaging bags, plastic lunch boxes, agricultural films, packaging materials, wood chips, and daily and medical plastics, have a short service life and are discarded at any time and scattered everywhere. It causes serious pollution to the environment, and a considerable part of the waste plastics ends up in urban waste. If it is not treated or directly landfilled, it will not only waste resources, but also cause long-term harm to the environment. Polyethylene (PE) is made of ethylene It is polymerized from monomers and can be processed by general thermoplastic molding methods. Plastics can be divided ...
