Abstract

The invention discloses a composite material for manufacturing rods of trolley cases. The composite material comprises, by weight, 20-30 parts of chloroprene rubber, 20-50 parts of butadiene rubber, 3-8 parts of vulcanizing agents, 0.5-1.5 parts of anti-scorching agents, 1-3 parts of tackifiers, 20-40 parts of ultrahigh molecular weight polyethylene, 15-30 parts of reinforcing agents, 2-6 parts of polytetrafluoroethylene and 1-3 parts of coupling agents. The invention further provides a method for preparing the composite material for manufacturing the rods of the trolley cases. The composite material for manufacturing the rods of the trolley cases and the method have the advantages that the composite material is good in toughness, abrasion resistance and self-lubricating properties, the butadiene rubber with excellent abrasion resistance and the ultrahigh molecular weight polyethylene are used as main raw materials, and the performance of the main raw materials further can be enhanced by the reinforcing agents and the coupling agents; the method is easy to implement and low in cost, the composite material prepared by the aid of the method can be used for manufacturing the rods of the trolley cases, is high in quality, light in specific gravity, convenient to stretch, low in friction and free of noise, and accordingly the composite material and the method are worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite material for manufacturing a rod body of a trolley case and a preparation method thereof. Background technique [0002] The trolley case refers to a suitcase with a pull rod and a roller. It is widely used because it is easy to use, and it is easy to carry clothes and the like for travel and going out. According to conservative statistics in 2004, the market capacity of China's bags reached 14 billion, and there is huge growth potential every year. In 2005, the number of Chinese tourists reached 1.212 billion, and the number of outbound tourists reached 31.0263 million. According to the "Tenth Five-Year Plan" for tourism development formulated by the China National Tourism Administration, by 2020, China's overseas tourism will exceed 210 million, and Chinese tourism will reach more than 2.9 billion. The huge number brings about the growing domestic consum...
