Abstract

The invention discloses a roll coating device and a coating technology. The roll coating device comprises a base, and a driving system (30), a three-roll down-taking or up-feeding system (40) and a defoaming feeding system (50) which are sequentially connected, wherein the three-roll down-taking or up-feeding system (40) comprises sequentially arranged two sets of metering rolls (6), two sets of material taking rolls (3) and two sets of coating rolls (4); sliding block guide rails (7) are connected on the base (1); the metering roll 1 (6) is driven by a driving motor (12); and sharp knives (9) are connected on the metering rolls (6). The coating technology carried out through adopting the roll coating device is simple in operation and high in automation degree, the poor coating is easy and convenient to treat, and a coated product is high in adhesive force, can meet the bending requirement of stainless steel OT, can resist 5% acid alkali for 24 hours without change, can resist salt mist for 240 hours, and reaches the eight-grade standard; and compared with an oil coating, the coating adopted by the invention is non-combustible, unexplosive, VOC emission-free, non-toxic, harmless, safe and environment, and meets the national environmental protection policy and laws and regulations.

Description

technical field

[0001] The invention relates to the coating field, in particular to a roller coating equipment and a coating process. Background technique

[0002] At present, there are many advantages of mechanical coating: improving quality, improving efficiency, reducing occupied site area, reducing personnel operation, reducing energy consumption, protecting personnel's health and avoiding environmental pollution.

[0003] In the field of painting and coating technology, most of the coatings in the existing coating machines are pumped into the material tank by air pump or diaphragm pump or directly supplied between the coating roller and the control roller, and will be produced in the material tank or coating roller. Bringing in a large number of tiny bubbles cannot be eliminated quickly. Because the surface tension of bubbles is different from that of no bubbles, it will lead to uneven thickness of the coating or bubble marks, forming fish eyes or uneven and smooth coat...
