Description
[technical field]
The present invention relates to the rubber accessory and make field, particularly a kind of rubber spraying coating process.
[background technology]
The spraying coating process of rubber weather strip has the dual mode spraying usually in the industry, a kind of is traditional off-line hand spray, and a kind of is the on-line automatic spraying that more and more producers adopt.The off-line spraying process is more, and human factor is more, and the stability of product quality is difficult to guarantee; Compared with the off-line hand spray, on-line automatic spraying method spraying thickness is more even, and film forming is harder close, and adhesive force is better, and gloss is natural beauty more, and quality is more stable, and sprayed on material and cost of labor are wasted still less, and cost is lower, and quality is more stable.Vehicle main frame producer is to the trust of on-line spray quality assurance with to each seal supplier's mandatory requirement in addition, and on-line automatic spraying replaces traditional off-line hand spray mode, has been trend of the times.At present the technological process of production of industry rubber weather strip is: refining glue → microwave vulcanization → hot-air cure → water cooling → Surface Treatment with Plasma → on-line spray → hot setting → moulding fixed length → connect angular position surface treatment → notes angle moulding → connect angular position spraying → postorder processing → packing to put in storage.The on-line spray maturation process is after the product sulfuration, use corona or plasma that product surface is handled, carry out hot setting after the spraying again, but need be at extruding production line configuration surface treatment facility and hot blast curing oven, need to drop into a large amount of funds, make production cost very high.
[summary of the invention]
The purpose of this invention is to provide a kind of technology for spraying rubber sealing strip on line, use this on-line spray technology can change traditional on-line spray mode, the spraying coating process of rubber weather strip is placed between the microwave vulcanization operation and hot-air cure operation of rubber weather strip, utilize existing two sections hot blast curing cages of production line to be cured after the part spraying, make the surface of rubber weather strip not need modification or processing, reduce the input of equipment funds, and indexs such as adhesive force of coatings, coefficient of friction, abrasion, surface quality meet the demands all after the spraying.
Technical scheme of the present invention to achieve the above object of the invention is: a kind of technology for spraying rubber sealing strip on line, this technology is between the microwave vulcanization operation and hot-air cure operation of rubber weather strip, this technology comprises the steps: 1) get the raw materials ready, be ready to needed curing agent, water, coating; 2) stir early stage, before batching, coating is fully stirred; 3) batching, each ingredients by weight umber is respectively: 7～10 parts in curing agent, 10～15 parts in water, 100 parts of coating; 4) curing agent and the water that measures fully is stirred 5? 0 minute, curing agent is dispersed in fully forms curing agent mixture in the water; 5) coating under condition of stirring in step 4) the curing agent mixture after scattered slowly add in the coating, and the limit edged stirs, mixing time at least 15 minutes forms coating compound; 6) spraying sprays rubber weather strip with the coating compound for preparing in the step 5), and wherein Pen Tu operating temperature is controlled in the 80-110 ℃ of scope; 7) solidify, the hot blast curing cage of the rubber weather strip that sprayed in the step 6) being put into 80 ℃-240 ℃ is cured 3-30 minute at least hardening time.
Wherein in described step 2) in stirred coating 8-12 minute with blade mixer.
Wherein in described step 3), can add water in right amount as if feeding-up.
Wherein in described step 5) as need add water, also want limit edged stirring, adding behind the water again, mixing time is 5-10 minute.
Wherein the soak time of the coating compound for preparing in described step 5) is 4 hours, that is: must use to prepare in the step 5) in described step 6) and finish 4 hours with interior coating compound.
Wherein in described step 6), rubber weather strip is sprayed preceding for guaranteeing that rubber weather strip goes out microwave vulcanization stove rear surface temperature and drops to rapidly in 110 ℃, rubber weather strip cools off spray gun with one before entering spray booth to the air blowing of rubber weather strip surface, at indoor another spray gun atomized water spray of spraying.
Because adopt above-mentioned technology, the present invention's technology for spraying rubber sealing strip on line has following beneficial effect:
1, effectively simplify the technological process of production, enhance productivity:
After adopting the present invention's technology for spraying rubber sealing strip on line, because this technology is between the microwave vulcanization operation and hot-air cure operation of rubber weather strip, the surface hydrophilicity of rubber after the surface hydrophilicity under the incomplete vulcanization situation is than the surface treatment of rubber process complete cure is much even, and can avoid the destabilizing factor of surface treatment procedure, can also directly enter hot setting, making coating and rubber fast instant is one, therefore, can remove the processing on the surface in the spraying process, water cooling, operations such as independent hot setting, realize directly in sulfidation, coating being sprayed onto product surface, production technology was by originally: refining glue → microwave vulcanization → hot-air cure → water cooling → Surface Treatment with Plasma → on-line spray → hot setting → moulding fixed length → connect angular position surface treatment → notes angle moulding → connect angular position spraying → postorder processing → packing to put in storage is reduced to: refine glue → microwave vulcanization → on-line spray → hot-air cure → water cooling → moulding fixed length → notes angle moulding → postorder processing → packing and put in storage.The purpose of can reach effective simplification technological process of production, enhancing productivity.
2, reduce production costs:
Because production technology is simplified, part producing equipment originally is omitted, and makes equipment investment reduce, and effectively reduces production costs.
3, technology is simple, reasonable
Because processing step of the present invention is fairly simple, only comprise get the raw materials ready, seven operations such as early stage stirring, batching, stirring, spraying, curing, and the also fairly simple production cost that can further reduce rubber weather strip of operation, in addition, the present invention is when carrying out on-line spray to rubber weather strip, by control reasonable process parameter (as proportioning, operating temperature and the hardening time of batching), make indexs such as its adhesive force of rubber weather strip spraying back, coefficient of friction, abrasion, surface quality all meet the demands.
