Abstract

The invention discloses a special home appliances material prepared from recyclable plastic. The formula of the special home appliances material contains recyclable plastic, polypropylene resin, polyolefin elastomer, filler, coupling agent, antioxidant and toner, wherein the raw materials of the recyclable plastic contain polypropylene random (PPR) copolymer pipes, washing machine barrels, cell cases, refrigerator drawers, air-conditioning outdoor machine cases, electric fan cases, vacuum cleaner cases and other polypropylene plastic materials. The prepared modified polypropylene can be used in washing machines, refrigerators, air conditioners and common small home appliances such as vacuum cleaners, hair driers and electric cookers. By adopting the special home appliances material, the raw material cost can be greatly reduced, the problems of waste of resources and environmental pollution can be eliminated to a certain extent, and circular economy and low-carbon development can be realized.

Description

[0001] technical field [0002] The invention belongs to the technical field of new materials, and in particular relates to the production of special materials for household appliances by using recycled plastics to modify polypropylene. Background technique [0003] In recent years, stimulated by a series of national policies to benefit the people, the rural economy has grown rapidly and consumer demand has also been released rapidly. Since last year, with the introduction of policies such as home appliances going to the countryside, my country's home appliance market has ushered in a new peak of production and sales. In 2009, the sales volume of home appliances nationwide was 858.9 billion yuan. It is expected that the sales of home appliances in 2010 will increase by more than 8% compared with last year, and the total will exceed 920 billion yuan. In addition, the small household appliance industry will reach a market size of 150 billion yuan. However, with the populariz...
