Problems solved by technology

Electroplating or electroless plating is used in production. The use of chemicals such as strong acid, strong alkali, and copper sulfate will cause a large amount of waste gas such as acid mist and alkali mist in the production environment, and the waste water generated will contain a large amount of heavy metals; Wear is the most difficult problem restricting the application of copper-free special coated welding wire. Under automatic welding conditions, contact tip wear not only affects the cost advantage of copper-free welding wire, but also seriously reduces the working efficiency of welding robots

Embodiment 1

[0017] 1. A preparation method of an anti-wear welding wire coating and a welding wire, characterized in that the method comprises the following steps:

[0018] Step 1. Weigh 10 parts of alumina powder, 30 parts of nickel oxide, 6 parts of calcium carbonate, and 4 parts of polytetrafluoroethylene in sequence, add them into a beaker containing 20 parts of n-hexane, and stir and mix for 10 minutes with magnetic force;

[0019] Step 2. Then transfer the material in the beaker to a horizontal colloid mill, and circulate the grinding for 2 hours to discharge the material. Transfer the obtained material to a vacuum drying oven at 75°C, dry for 3 hours, sieve, and collect 120-mesh mixed powder;

[0020] Step 3. Put the mixed powder obtained above into a mixer, then add 3 parts of potassium chlorate and 5 parts of magnesium powder, start the mixer of the mixer, stir and mix at a speed of 350r / min for 20min, and discharge;

[0021] Step 4, add the above materials into the mold, control...

Embodiment 2

[0029] Step 1. Weigh 8 parts of alumina powder, 30 parts of nickel oxide, 6 parts of calcium carbonate, and 4 parts of polytetrafluoroethylene in sequence, add them into a beaker containing 20 parts of n-hexane, and stir and mix for 10 minutes with magnetic force; the rest of the steps are implemented in the same way example 1.

Embodiment 3

Abstract

The invention discloses a wear-resistant welding wire coating and welding wire preparation method. The method is characterized in that aluminum oxide powder, nickel oxide, calcium carbonate, polytetrafluoroethylene, n-hexane, potassium chlorate, magnesium powder, graphite powder, boron nitride and acrylic resin are taken as main raw materials. According to the method, the preparation process is good in stability and high in reliability, a coating is wide in application range, and the large-scale industrial production of copper-free welding wires is facilitated.

Description

technical field [0001] The invention relates to an anti-wear welding wire coating and a preparation method of the welding wire, belonging to the field of preparation and protection of welding wire material coatings. Background technique [0002] It is the current development trend to replace copper-plated welding wire with copper-free welding wire. With the increasing application of copper-free welding wire in the market in recent years, there is more room for development. However, a series of environmental protection problems will arise in the production and use of copper-plated welding wire. Electroplating or electroless plating is used in production. The use of chemicals such as strong acid, strong alkali, and copper sulfate will cause a large amount of waste gas such as acid mist and alkali mist in the production environment, and the waste water generated will contain a large amount of heavy metals; Wear is the most difficult problem restricting the application of coppe...
