Description
Technical field
The present invention relates to a kind of flocked substrates artificial leather and processing method thereof.
Background technology
Along with the continuous application of various new materials, new technology, the PVC artificial leather is also being brought in constant renewal in the replacement.Through years of development, the PVC artificial leather is used widely in a plurality of fields such as case and bag, footwear, clothes, furniture, automotive trim, sports entertainment articles, gets into daily life, shines vigorous commercial viability.At present, mahjong desktop cloth that public recreation is used, very big some is the flocking on cloth cover of flocking factory, makes it the villous sense, thereby processes matte.But the loss of this type of cloth suede product is big, cost is high, and especially the fine hair on the cloth cover very easily comes off, and bothers very much during the secondary flocking, and the cost of old for new service is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of flocked substrates artificial leather, makes that the bonding strength of itself and fine hair is good, the fine hair difficult drop-off.
The technical problem that the present invention also will solve provides the processing method of above-mentioned flocked substrates artificial leather.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is following:
A kind of flocked substrates artificial leather, it comprises the component of following parts by weight: 100 parts of Corvics, 40～50 parts of dioctyl phthalates, 2～3 parts of barium zinc stabilizers, 4～6 parts of blowing agents, 5～8 parts of titanate coupling agents.
Wherein, described blowing agent is FD-115.
The processing method of above-mentioned flocked substrates artificial leather comprises the steps:
(1) with 100 parts of Corvics, 40～50 parts of dioctyl phthalates, 2～3 parts of barium zinc stabilizers and 5～8 parts of titanate coupling agents, mixes;
The material that (2) will mix is put into ten thousand horsepowers of machine banburyings, when electric current reaches 100A, puts into 4～6 parts of blowing agents, and banburying is 20～60 seconds again;
(3) banburying is good material is put into mill, and material is fully plastified;
(4) good material is evenly sent into extruder will to open refining, evenly extrudes;
(5) extruded material evenly rolls film forming through four-roll calender, and is fitted on the thin fabricbase of one deck;
(6) film of calendering after compound makes after through the baking oven foaming.
In the step (2), put into blowing agent after, preferred banburying 30 seconds.
In the step (3), the temperature of mill is controlled at 160～180 ℃, preferred 170 ℃.
In the step (4), the temperature of extruder is controlled at 130～140 ℃, preferred 135 ℃.
In the step (5), four roll temperatures are respectively: 190～200 ℃ on a roller, and 185～195 ℃ on two rollers, 170～175 ℃ on three rollers, 160～170 ℃ on four rollers, preferred temperature is: 195 ℃ on a roller, 190 ℃ on two rollers, 172 ℃ on three rollers, 168 ℃ on four rollers.The calendering linear speed is controlled at 50～70 meters/minute, preferred 60 meters/minute.
In the step (6), baking oven divides six districts, and each is distinguished temperature and is controlled to be respectively: 155～165 ℃ in a district, 195～205 ℃ in two districts; 225～235 ℃ in three districts, 225～235 ℃ in four districts, 195～205 ℃ in five districts, 145～155 ℃ in six districts; Preferred temperature is: 160 ℃ in a district, 200 ℃ in two districts, 230 ℃ in three districts; 230 ℃ in four districts, 200 ℃ in five districts, 150 ℃ in six districts.The oven line speed control is made as 10～30 meters/minute, preferred 20 meters/minute.
Beneficial effect: the suede that adopts flocked substrates artificial leather of the present invention to process, similar products on the market, feel, sense of touch are good; Resilience is superior, and the fine hair sense is strong, tearing strength high (reach like product 1.6 times); Degree of adhesion good (peel strength reaches 1.4 times of like product), fine hair difficult drop-off, non-foaming, ageing-resistant performance good (reaching 5 grades); Hydrolysis, acid-proof alkaline are strong, and scratch resistance is high, are prone to clean.And the flocking cost is lower, and processing technology is simple, and easy operating is the best replacer of flocking cloth, is that the ideal of making mahjong desktop cloth or other similar physical culture amusing products is at present selected.
