Problems solved by technology

[0004] However, since the balance weight currently only has three weights, and the iron balance weight is less flexible, it cannot be cut into any weight at will, and the balance adjustment of the wheel hub is not very accurate, and the iron balance weight is easy to rust

Abstract

The invention discloses an automotive adhesion type balancing block and a preparation process thereof. The automotive adhesion type balancing block comprises a balancing block body, an adhesive part and release paper which are connected with one another sequentially; the balancing block body consists of stainless steel powder treated by metal powder or silicate aqueous solution, composite resin and an additive; the stainless steel powder comprises the following components in percentage by mass: less than or equal to 0.12 percent of carbon, less than or equal to 1 percent of silicon, less than2 percent of manganese, less than or equal to 0.045 percent of phosphorus, less than or equal to 0.03 percent of sulfur, 16 to 20.2 percent of chromium, 8 to 10.5 percent of nickel and the balance ofiron and unavoidable impurities; and the metal powder is prepared from mixing nickel or chromium into iron powder, the mass ratio of the iron powder to the nickel is 10:(1-2) and the mass ratio of theiron powder to the chromium is 10:(0.5-1.5). The automotive adhesion type balancing block provided by the invention has the advantages of excellent flexibility, capability of being cut into any weight, high anti-oxidation and anti-rust properties and strong and durable adhesive force.

Description

technical field [0001] The invention relates to the technical field of auto parts, more specifically, it relates to a bonded balance weight for automobiles and a preparation process thereof. Background technique [0002] Generally, if the wheel hub of a car has uneven parts, it will vibrate according to the centrifugal force during rotation, so there will be noise and tire wear, causing the steering wheel to tremble. The centrifugal force is proportional to the rotation speed during the rotation of the tire, so when driving at high speed, The balance of the wheel hub must be accurate. Balance is divided into static balance and dynamic balance in nature. Unbalanced static balance will easily cause the wheel hub to vibrate up and down, and unbalanced dynamic balance will cause the wheel hub to shake left and right. The corresponding balance weight is installed on the best position opposite the balance part to balance the centrifugal force in the opposite direction. [0003] B...
