Abstract

The invention relates to a plastic chain riveting, the raw materials of which are calculated by weight: 40-60 portions of nylon, 40-60 portions of glass fiber, 0-10 portions of mineral powder, 0.1-0.5 portion of coupling agent, 0.1-0.5 portion of antioxidant, and 0.3-2 portions of lubricant. The plastic chain riveting made by the invention is characterized by long service life without treatment and comparatively long-term high strength and high rigidity maintenance, which is applicable to common electrical or air staple guns, with good comprehensive mechanical property, strong corrosion resistance, light mass and simple forming of products, and grinding and shaving can be done during usage, thus various components with complex shapes can be easily machined.

Description

technical field [0001] The invention relates to a nail row, in particular to a plastic nail row used by an electric or pneumatic nail gun. Background technique [0002] In modern construction and manufacturing, a large number of nails are required for fastening. In order to meet the requirements of high-speed development and automation, electric or pneumatic tools are used in more and more places, and row nails have gradually replaced traditional nails. But most of the row nails used at present are to adopt galvanized iron nails, which have many defects such as easy to get rusty, short life, and troublesome manufacture. Replacing steel with plastic is a trend in the future development of fasteners. Chinese Patent Application No. 93112495.6 discloses a method for making plastic nails from glass fiber-reinforced thermoplastic resin materials. Chinese patent application number 95113087.0 discloses a plastic alloy nail and a plastic bolt, which are used to replace ordinary iro...
