Problems solved by technology

[0004] The bending failure load of the PE wood-plastic floor provided by the above technical solution reaches above 4600N. At the same time, the present invention has the advantages of low water absorption, good low temperature resistance and oxidation resistance. However, the product obtained by using this solution has a higher Wood powder content, impact strength decreased, affecting the impact resistance of the material

Embodiment 1

[0027] A kind of degradable polypropylene wood-plastic composite modified material, by weight, by 30 parts of wood flour, 45.5 parts of polypropylene, 19.5 parts of glass fiber, 2 parts of zinc stearate, 1 part of vinyl bis stearamide, Consists of 1 part compatibilizer and 1 part polyethylene wax.

[0028] Wherein, the wood powder is obtained by drying birch sawdust at 60-80° C. until the water content is less than 5 wt %, ball milling for 2.5 hours and passing through a 100-mesh sieve. The glass fiber is short glass fiber with a length of 0.2-0.6mm, and the compatibilizer is maleic anhydride grafted compatibilizer.

Embodiment 2

[0030] A degradable polypropylene wood-plastic composite modified material, in parts by weight, consists of 25 parts of wood powder, 50 parts of polypropylene, 20 parts of glass fiber, 1 part of zinc stearate, 2 parts of vinyl bis stearamide, Consists of 1 part compatibilizer and 1 part polyethylene wax.

[0031] Wherein, the wood powder is obtained by drying oak sawdust at 60-80° C. until the water content is less than 5 wt %, ball milling for 1.5 hours, and passing through a 100-mesh sieve. The glass fiber is short glass fiber with a length of 0.2-0.6mm, and the compatibilizer is acrylic graft compatibilizer.

Embodiment 3

[0033] A degradable polypropylene wood-plastic composite modified material, consisting of 40 parts of wood flour, 40 parts of polypropylene, 18 parts of glass fiber, 1 part of zinc stearate, 0.2 parts of vinyl bis stearamide, and 0.5 parts of compatibilizer and 0.3 parts of polyethylene wax.

[0034] Wherein, the wood flour is obtained by drying bamboo fiber at 60-80° C. until the moisture content is less than 5 wt %, ball milling for 3 hours, and passing through a 100-mesh sieve. The glass fiber is short glass fiber with a length of 0.2-0.6mm, and the compatibilizer is maleic anhydride grafted compatibilizer.

Abstract

The invention belongs to the technical field of high polymer materials, and relates to a degradable polypropylene wood-plastic composite modified material which comprises wood flour, polypropylene, glass fibers, zinc stearate, vinyl bis stearamide, a compatilizer and polyethylene wax. The wood-plastic composite material is reinforced by adopting the glass fibers, and the glass fibers are compounded with the wood flour and the polypropylene under the action of the auxiliaries, so that the wood-plastic composite material has higher impact strength, and the impact resistance of the composite material is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a wood-plastic material, in particular to a degradable polypropylene wood-plastic composite modified material. Background technique [0002] Wood-plastic, that is, wood-plastic composites (Wood-Plastic Composites, WPC), is a new type of composite material that has been booming at home and abroad in recent years. Wood flour, rice husk, straw and other waste plant fibers are mixed into new wood materials, and then processed by extrusion, molding, injection molding and other plastic processing techniques to produce boards or profiles. Mainly used in building materials, furniture, logistics packaging and other industries. The board formed by hot extrusion after mixing plastic and wood powder in a certain proportion is called extruded wood-plastic composite board. [0003] For example, the Chinese invention patent application with the authorized announcement number CN1053488...
