Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that although polyethylene has excellent characteristics such as corrosion resistance, acid and alkali resistance, and low temperature resistance, there are still certain deficiencies in the aging resistance of polyethylene, which makes it difficult to use bionic rattan chairs for a long time. After that, the bionic rattan chair still has the possibility of aging and damage, which leads to the defect that the bionic rattan chair still has a relatively short service life

Abstract

The invention relates to the technical field of leisure household articles, and especially relates to a polyethylene and polyvinyl formal composite material, a preparation method thereof, and a bionic rattan chair. The polyethylene and polyvinyl formal composite material is prepared from, by weight, 40-50 parts of polyethylene, 30-40 parts of polyvinyl formal, 14-22 parts of color master batch and 5-9 parts of a fiber material. The preparation method of the polyethylene and polyvinyl formal composite material comprises the following steps: (1) preparing a polyethylene and polyvinyl formal base material; and (2) performing injection molding to obtain the polyethylene and polyvinyl formal composite material. The polyethylene and polyvinyl formal composite material and the preparation method thereof have the effects of improving the aging resistance of the bionic rattan chair and prolonging the service life of the bionic rattan chair.

Description

technical field [0001] This application relates to the technical field of leisure household products, more specifically, it relates to a polyethylene, polyvinyl formal composite material and its preparation method and a bionic rattan chair. Background technique [0002] The rattan chair, as the name suggests, is a chair made of rattan skin, rattan core and rattan. Because of its excellent air permeability and elasticity, the rattan chair also has the characteristics of warm in winter and cool in summer and high comfort. Advantages, and then widely used in families in Southeast Asia. However, because the plant rattan is difficult to preserve for a long time, the rattan chair prepared from the plant rattan still has the shortcoming of a short service life. [0003] In related technologies, in order to prolong the use time of rattan chairs, polyethylene bionic rattans made of polyethylene are used in the market to replace plant rattans. Since polyethylene has excellent charact...
