Description
Technical field
The invention belongs to the case and bag preparing technical field, especially a kind of preparation technology of PC case.
Technical background
As the main equipment of trip, the effect of case and bag in route is of crucial importance, is top priority for luggage provides outstanding protection.Therefore, require it not only to have the property of holding, also will have function, especially case and bag such as anti-extrusion, waterproof, anticollision will hold luggage simultaneously, the weight that therefore reduces case and bag itself to greatest extent also is that people pursue.Wherein, this material of Merlon (PC) from aircraft industry, it is as light as Lady Fly Swallow of the Han Dynasty who could "dance on a man's palm." but as hard as steel, and crashproof effect is outstanding, and the position that is impacted is reinstatement voluntarily almost; Also be a kind of armorphous thermoplastic resin of high comprehensive performance, have excellent electrical insulating property, extensibility, dimensional stability and chemical resistance, higher intensity, hear resistance and cold resistance; Also have from put out, advantage such as fire-retardant, nontoxic, pigmentable; Especially very light of PC material; Application in the case and bag of needs carryings just more can embody its characteristic, and like Chinese application number: 200510032070.6 document just discloses a kind of PC box material; It is made up of PVC film and high-molecular material A BS, SBS, DBY and paraffin; Though the plane bearing capacity improves 3.5 times, shock-resistant ability improves nearly 5 times, and present case and bag can not be accomplished the 100%PC material.
Summary of the invention
The invention provides a kind of preparation technology of the PC case of making of 100%PC material, this method not only technology is simple, and the PC case of being produced is in light weight, the 25kg that can bear a heavy burden, modification not under the 90cm height.
In order to reach above-mentioned purpose, technical scheme of the present invention is:
A kind of preparation technology of PC case comprises being prepared as follows step:
Steps A, the PC material with 100% after 6 hours, make dry PC material through 250 ℃ of high temperature removal moisture drying;
Step B, colorant is allocated, through mixer 40 minutes, after high temperature removal moisture drying processed, obtained allocating colorant more earlier; Make color reach the brightest, the brightest, color reaches best effect;
Step C, throw into the material of the dry PC described in 0.01～10 part and 1000～25000 parts steps A of 0.1～15 part of fusing agent, UMP reducing agent of listed as parts by weight in the agitated reactor together; Again 1～10 part for preparing among the step B allotment colorant is thrown in the agitated reactor after fully stirring, made the PC raw material after fully mixing; Make color reach effect best and that material is the most soft.
Step D, gained PC raw material among the step C is made PC sheet material with make-up machine, mould high-temperature molding;
Step e, gained PC sheet material among the step D is covered with PE protects overlay film, cutting makes finished product sheet material;
Step F, gained finished product sheet material in the step e is sent into the dehumidifying room dehumidify, assembling at last obtains finished product PC case.
Preferably, PC material moisture content is reduced to below 0.02% in the said steps A.
Preferably, in the step F, the room humidity that will dehumidify makes at 75～45 degree.Sheet material does not absorb the outside aqueous vapor, just can normally use;
Preferably, among the said step D, the temperature when said make-up machine, mould high-temperature molding is 70 ℃～280 ℃, and the time was controlled at 1～20 second.
Preferably, in the said step e, when said PC sheet material was covered with PE guarantor overlay film, the temperature of whole film covering process was controlled at more than 100 ℃.
The present invention mainly adopts the UMP reducing agent, through the control to UMP reducing agent and thawing agent consumption, and controls on humidity, the temperature and time in process of production; Not only operation is simple to make the present invention; And broken the traditional technology that can not expect to do case and bag with 100% pure PC, and the PC case of especially producing through the present invention, thickness is consistent; Smooth surface, pore-free, anti-folding, tension, intensity is high, in light weight, 25kg can bear a heavy burden; Under the 90cm height not modification, do not break, strong (low temperature is at-12 ℃, and freezing 4 hours, high temperature toasted 100 hours about 80 ℃) not modification, the nondiscolouring of temperature resistance; Reach the examination criteria of international testing agency (TV Rheiniand.CO.Ltd), the physical property sheet material of high-quality.
