Abstract

The invention discloses a high-strength corrosion-resistant plastic screw. The screw comprises a screw rod, a screw head integrally connected with one end of the screw rod, and a locking disc head arranged at the other end of the screw rod in a sleeving mode, wherein an external thread structure is integrally machined on the screw rod, and the screw rod, the screw head and the locking disc head are all made of high-strength corrosion-resistant plastic. The high-strength corrosion-resistant plastic comprises the following raw materials of, by weight, 58%-62% of PA6, 25%-28% of glass fiber, 8%-12% of nano silicon dioxide and 4%-8% of nano aluminum oxide. According to the high-strength corrosion-resistant plastic screw, through the above mode, the screw rod, the screw head and the locking disc head are all made of the high-strength corrosion-resistant plastic with an excellent formula, and have excellent strength and corrosion resistance, and the phenomena of screw loose and breaking in the using process of the screw are avoided.

Description

technical field [0001] The invention relates to the field of non-standard screws, in particular to a high-strength corrosion-resistant plastic screw. Background technique [0002] Compared with ordinary metal screws, the biggest advantage of plastic screws is that it has good insulation, non-conductivity, and no rust. However, the biggest defect of plastic screws is that they are not as strong as ordinary metal screws, and the teeth may slip or break if the torque is too large. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a high-strength corrosion-resistant plastic screw, which can solve the above-mentioned defects existing in the existing plastic screws. [0004] In order to solve the above technical problems, a technical solution adopted by the present invention is to provide a high-strength corrosion-resistant plastic screw, including: a screw rod, a screw head integrally connected with one end of the scre...
