Abstract
A kind of magnetized plastic sheet is that the plastics mutual bonding or heat seal by two layers or three layer plane shapes constitute.Ground floor and the 3rd layer are thinner.The centre is thicker, can be used as the chart board veneer after bumping, magnetic " blackboard ", and cartographic model, Chart Lines and chess etc., easy to use with the said goods of its making, be easy to carry, surfacing is smooth, and is goodlooking.
Description
The present invention relates to the making and the application thereof of magnetized plastic sheet.
At present, drawing board commonly used all is wooden, and drawing is with drawing pin or the fixing relatively inconvenience of use of adhesive tape, also easily causes the damage of drawing board and drawing.Magnetic " blackboard " commonly used is all made with sheet iron, but because of heavier with can not fold inconvenience and carry, the scope of application is greatly affected.
In view of plastic sheet has advantages such as the processing of being easy to, low, flexible good, the high resilience of density, hardness is moderate, make it promptly have magnetic pull after the magnetization.That the drawing board that this magnetized plastic sheet is made, magnetic " blackboard " have is in light weight, be easy to carry, easy to use, advantage such as flexibility is big.In addition, this magnetized plastic sheet also can be made printing veneer PVC film overlay panel and banded industrial goods end socket etc., has widely and uses.
The present invention's purpose is to make magnetized plastic sheet, to satisfy needs such as making magnetic chart board, magnetic " blackboard ", magnetic veener and end socket.
The present invention realizes above-mentioned purpose like this:
This composite magnetized plastic sheet is made of the mutual bonding or heat seal all-in-one-piece igelite of two layers or three layers, and its ground floor (top layer) is that thickness is common coloured polychloroethylene film of 0.04～0.3 millimeter; The second layer (sorption layer) is a magnetized plastic sheet, and the 3rd layer (also can not having this layer) is that thickness is coloured polychloroethylene film of 0.04～0.3 millimeter.They are bonding with polyvinyl chloride adhesive, perhaps use heat seal (laminating) and become one.Wherein, the prescription of the second layer (sorption layer) is as follows:
Barium ferrite powder 100～110(parts by weight)
Corvic 5～7
Plasticizer 7～9
Stabilizing agent 0.5～1
Lubricant 1～1.5
Its technological process and process conditions are as follows:
1. get all the raw material ready by above-mentioned prescription
2. mediate: with the homogenizer temperature is 90 ℃～110 ℃, the time: 35～45 minutes
3. mixing: temperature is 120 ℃～125 ℃, 20～30 minutes time
4. calendering: 140 ℃～145 ℃
5. magnetize: the magnetic field intensity that magnetizes of magnet charger is 1200 oersteds, and the back magnetic sheet surface magnetic flux density that magnetizes can reach more than 400 Gausses.
6. bonding: PVC plastic foil and magnetic plastics is bonding with commercially available polyvinyl chloride adhesive, perhaps PVC plastic foil and magnetized plastic sheet are become one with known heat seal (laminating) heat seal, composite magnetized plastic sheet.
The number of plies size of composite magnetized plastic sheet of the present invention, shape are different because of different purposes.
The chart board of Fig. 1-three-decker and magnet board profile
The chart board of Fig. 2-two-layer structure and magnet board profile.
Wherein: 1, woven design Polypropylence Sheet, 2, magnetized plastic sheet, 3, Polypropylence Sheet.
Its concrete prescription of one embodiment of the invention is:
Get barium ferrite powder 100 gram gram, Corvic 70 grams, dioctyl phthalate 60 grams, calcium stearate 5 grams, stearic acid 10 grams, through mediate, mixing, the veneer that rolls, magnetizes promptly becomes magnetic piece.
