Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0016] The invention discloses a protective material for spraying workshops, which comprises: a base cloth, which includes polyester fibers and conductive fibers; and a surface layer bonded to the base cloth by reactive polyurethane hot melt adhesive. Carbon fiber conductive filaments are added to the base cloth of the present invention. The adhesion effect of the reactive polyurethane hot-melt adhesive material used in the present invention can fully meet the requirements, and after testing, there is no shedding and separation phenomenon after soaking in an organic solvent for 480 hours. And the fiber shedding is in line with the "Shallow Fiber Test Specifications for Paint Workshops", and the number of shedding fibers is <1 / square centimeter.
[0017] Further, the base fabric includes 96% polyester plus 4% conductive fibers. The problem of static electric...

The invention discloses a protective material for a painting workshop. The protective material comprises base fabric and a surface layer, wherein the base fabric comprises a polyester fiber and conductive fiber; and the surface layer is glued on the base fabric by a polyurethane reactive hot-melt adhesive. The invention also discloses a processing technology of the protective material for a painting workshop, comprising the following steps: coating the upper surface of the strip-shaped base fabric with the polyurethane reactive hot-melt adhesive, covering the polyurethane reactive hot-melt adhesive with the surface layer, laminating the base fabric and the surface layer between the two pinch rollers, and preforming the laminated base fabric and surface layer through rotation of a receivingtray. By gluing the surface layer and the base fabric through the polyurethane reactive hot-melt adhesive, degumming is effectively avoided; and by adding the conductive fiber in the base fabric, static electricity can be released through the conductive fiber.
Description
technical field [0001] The invention relates to a protective material and a processing technology thereof, in particular to a protective material for a spraying workshop and a processing technology thereof. Background technique [0002] At present, major automobile factories and various spraying industries have used robots to replace manual operations. Due to the relatively high environmental requirements of the spraying industry (dust-free workshop) and explosive environments, multiple fire accidents caused by static electricity have caused the entire The industry has attached great importance to the protection of robots. In order to solve the problem of robot protection on the spraying production line, our company took the lead in investing in R&D personnel and spent nearly 3 years developing a machine that can meet the requirements of the "Fiber Test Specifications for Spraying Workshops". Material. [0003] The materials in the prior art have static electricity and insu...
