Abstract
The invention discloses a preparation method for a sodium naphthalene treatment liquid and a process of treating a PTFE product with the sodium naphthalene treatment liquid. The preparation method comprises the following steps of: a, selecting raw materials; b, controlling temperature; c, carrying out dissolving; and d, keeping the liquid in a dark place. According to the preparation method for the sodium naphthalene treatment liquid and the process of treating the PTFE product with the sodium naphthalene treatment liquid disclosed by the invention, the surface roughness of the PTFE product treated by the sodium naphthalene treatment liquid is greatly increased, and the actual binding area is increased, so that binding is facilitated. The water contact angle of the PTFE product treated by the sodium naphthalene treatment liquid is greatly reduced, so that good binding is achieved. The method is relatively good in effect and less in dangerousness, is widely applicable and can be suitable for polytetrafluoroethylene, polytrifluorochloroethylene and fluorine-containing copolymers.
Description
Technical field
The invention belongs to chemical field, particularly a kind of compound method of naphthalene sodium treatment solution and the technique for the treatment of PTFE goods thereof.
Background technology
Tetrafluoroethylene (PTFE) is a kind of macromolecular material of excellent property, be used as special engineering plastics the earliest, because it has the performances such as excellent chemical stability, electrical insulating property, extremely low kinetic friction coefficient, nonflammable, resistance to chemical attack, be called as " kings of plastics ".After this polytetrafluoroethylmicroporous microporous membrane is successfully applied to filtering material and waterproof moisture permeating fabric.Not surface treated tetrafluoroethylene, surface can not infiltrate by glue paste, become the most difficult sticky material in synthetic materials, limit its application.Probe into its difficult viscosity reason, because tetrafluoroethylene is a kind of nonpolar linear type crystalline polymer, although each carbon atom connects the very strong fluorine atom of two polarity in molecular structure, because the symmetry of its structure is very high, its polarity is cancelled out each other, and presents nonpolar; Its surface energy of PTFE is very low, and critical surface tension only has 1.85 × 10
-2n/cm.Mainly improve its cohesive strength by chatting surface active for improving PTFE cohesive strength both at home and abroad at present, main method has: radiation grafts the ammonia solution method, sodium-bitter edible plant tetrahydrofuran solution method etc. of method, plasma activation, Potassium ethanoate activation method, sodium Metal 99.5.Wherein the representational method of most is the treatment solution modification of naphthalene sodium and plasma modification, but plasma modification instrument is expensive, condition is harsh, and its technique of naphthalene sodium treatment solution modification is simple, cost is low, effective.
Tetrafluoroethylene (PTFE)-sodium naphthalene solution-treated bonding method: sodium naphthalene solution-treated fluorine material, mainly by corrosive fluid and PTFE plastics generation chemical reaction, tear off the part fluorine atom on material surface, so just leave carburization zone and some polar group from the teeth outwards.
Sodium naphthalene solution-treated fluorine material, mainly by corrosive fluid and PTFE plastics generation chemical reaction, tears off the part fluorine atom on material surface, so just leaves carburization zone and some polar group from the teeth outwards.Infrared spectra shows, hydroxyl, carbonyl and unsaturated link(age) isopolarity group are introduced in surface, and these groups can make surface energy increase, and contact angle diminishes, and wettability improves, and becomes can glue from difficulty is sticky.This is that in all methods of research at present, effect is better, is also the method relatively commonly used.There is the problems such as weak effect in existing naphthalene sodium treatment solution.
Summary of the invention
A kind of compound method of naphthalene sodium treatment solution and the technique for the treatment of PTFE goods thereof are the object of this invention is to provide, to solve the problems of the prior art.
For achieving the above object, the present invention is by the following technical solutions:
A kind of naphthalene sodium treatment solution compound method, comprises the following steps:
Step a, choose chemical pure fresh sodium, thin refined naphthalene; Analytically pure tetrahydrofuran (THF) is as raw material;
Step b, with the volume of tetrahydrofuran (THF) for benchmark, choose 1000ml tetrahydrofuran (THF), add in there-necked flask, put into ice bath stir cooling; Temperature is controlled to 0-10 DEG C;
Step c, slowly add after thin refined naphthalene 128g stirs at room temperature and atmospheric pressure, fresh for 23g sodium sheet is divided three times and slowly adds reaction vessel to four times, interval 20-45 minute in each, and constantly stir, make it whole dissolving; Solution is blackish green or chocolate, and reaction process meeting heat release, is strictly on guard against that water immerses; This process is two and one-half-hours;
Steps d, the naphthalene sodium treatment solution prepared is put into sealed vessel, keep in Dark Place.
Further, in described step a, tetrahydrofuran (THF) dewaters, and its method is: add sodium silk 1g in 1L tetrahydrofuran (THF), 70 degree of backflows 3 hours, then air distillation.
Naphthalene sodium treatment solution process PTFE product process, comprises the following steps:
Steps A, first good to turning polytetrafluoroethylproducts products, include tetrafluoroethylene sheet material or polytetrafluoroethylene film acetone or alcohol washes, removing surface and oil contaminant and foul;
Step B, at room temperature by clean polytetrafluoroethylproducts products immerse fill put into prepared naphthalene sodium treatment solution dipping 10 minutes after take out;
Step
c, first with normal-temperature water cleaning, put into 90 DEG C of hot water and clean, residue such as removing NaH and NaOH etc., treats that ptfe surface is dark-brown, both for being disposed, to dry or by oven for drying, then rewinding;
Step D, use black light-blocking film packed for standby use.
Beneficial effect of the present invention: the compound method of naphthalene sodium treatment solution of the present invention and the technique for the treatment of PTFE goods thereof, the PTFE product surface roughness of naphthalene sodium treatment solution process increases greatly, add actual bond area, be beneficial to bonding, the feeler of PTFE goods water after the surface treatment of naphthalene sodium greatly reduces, thus achieves good bonding.This method effect is better, dangerous little, is widely used, and is applicable to tetrafluoroethylene, voltalef and closes fluo-copolymer.
