Problems solved by technology

[0004] Due to its particularity, the surface of the aircraft body must have an antistatic function, and the method commonly used in the world is to spray antistatic liquid in the resin sand, so that the surface of the sand has antistatic ability, and the surface of the aircraft body has an antistatic function; but It also brings a trouble, that is, the antistatic liquid needs to be sprayed repeatedly when the resin sand is reused, which not only increases the cost of materials and labor for each use, but also increases the preparation time

Abstract

The invention provides antistatic resin sand which is characterized in that the raw materials comprise the following components in part by weight: 200 to 270 parts of urea, 370 to 530 parts of formaldehyde, 15 to 25 parts of urotropine, 110 to 150 parts of filler and 18 to 25 parts of other auxiliary materials; and the antistatic resin sand also comprises an antistatic agent of which the weight is 0.2 to 0.6 percent of the total weight of the components. The invention also provides a production method of the antistatic resin sand, which comprises the following steps of synthesizing urea resin, carrying out kneading process, carrying out drying process, carrying out grinding process, carrying out ball milling and sieving, carrying out pelletizing process, carrying out size stabilization process, mixing, packaging and the like. According to the antistatic resin sand and the preparation method thereof, which are provided by the invention, the antistatic resin sand has antistatic capacity; various requirements on the surface treatment on an airframe are met; and particularly, in the using process of the antistatic resin sand, antistatic liquid does not need to be sprayed to the resin sand.

Description

technical field [0001] The invention relates to a resin sand and a preparation method thereof, in particular to an antistatic resin sand used for the surface treatment of an aircraft body and a preparation method thereof. Background technique [0002] The traditional method of treating the surface of aircraft body is to use corundum polishing process. Due to the high hardness of abrasive corundum, the surface of the body will be rough or slightly damaged, but this treatment method is still in use today. [0003] For the treatment of the surface of aircraft body, developed countries have generally adopted resin sand spraying technology. Due to the moderate hardness of resin sand, it can remove the paint on the surface of the aircraft body without causing surface roughness, so it is widely used in developed countries. [0004] Due to its particularity, the surface of the aircraft body must have an antistatic function, and the method commonly used in the world is to spray antis...
