Abstract
The present invention relates to a double-face reinforced fat-resistant film and a manufacture method thereof. The double-face reinforced fat-proof film is made of a reinforced fat-resistant precise filtering material. The film has the characteristics of thin material, uniform distribution of filtering holes, high filtering speed, less adsorption, no medium desquamation, high intensity, realization of continuous production, mass production, high efficiency, etc. The film can be widely applied to electron industry, medicine industry, food industry, beverage industry, national defense industry, chemical industry, etc.
Description
Technical field of the present invention relates to anti-adipose membrane of a kind of two-sided reinforcement and manufacture method.
At present, the film that uses on the domestic market is the single face strengthening membrane, and this film flow velocity is slow, and face and enhancement Layer easily come off, cracky, and result of use is poor, and range of application is narrow, should not promote the use of.
The objective of the invention is: develop anti-adipose membrane of a kind of two-sided reinforcement and manufacture method.
Technical solution of the present invention is: the anti-adipose membrane of a kind of two-sided reinforcement, its film forming liquid is made up of nylon (6), formic acid, nonwoven, acetic anhydride or dimethyl sulfoxide (DMSO), dimethyl formamide or dimethylacetylamide, Tween-80, glycerine, ether, n-butanol or ethanol or isobutanol, and its component is (is benchmark with formic acid) % (weight):
Formic acid 100% glycerine 0.1-1%
Nylon (6) 10-45% ether 1-25%
An amount of n-butanol 1-20% of nonwoven
Acetic anhydride 1-20% ethanol 1-20%
Dimethyl formamide 1-10% isobutanol 1-20%
Dimethylacetylamide 1-10% dimethyl sulfoxide (DMSO) 1-20%.
Tween-80 0.1-1%
Best component is (%):
Formic acid 100% glycerine 1%
Nylon (6) 27% ether 17%
An amount of n-butanol 9% of nonwoven
Acetic anhydride 5% ethanol 9%
Dimethyl formamide 4% isobutanol 9%
Dimethylacetylamide 4% dimethyl sulfoxide (DMSO) 5%.
Tween-80 0.3%
The manufacture method of the anti-adipose membrane of two-sided reinforcement is: earlier nylon (6) and formic acid are carried out mixed dissolution, add acetic anhydride or dimethyl sulfoxide (DMSO), dimethyl formamide or dimethylacetylamide, Tween-80, glycerine, ether, n-butanol or ethanol or isobutanol again, putting into mixer together stirs, filter blowing, discontinuous degassing is put into automatic knifing machine again, on nonwoven, carry out knifing, evaporation then, water flushing, oven dry film forming.Temperature in the mixer is preferably 20-25 ℃.Automatically the temperature in the knifing machine preferably is heated to 40 ℃ from 30 ℃.
This film is the anti-fat secondary filter of an a kind of reinforcement material, can be widely used in industries such as medicine, electronics, food, chemical industry, national defence, is a kind of emerging new and high technology, has remarkable economic efficiency and social benefit.
