Technical Field
The invention relates to the technical field of protective materials, in particular to a protective plate and a preparation method thereof.
Background
At present, protection plates used in child paradises in naughty fort on the market are all made of EPE pearl wool foaming materials, surface pictures are printed by films and subjected to heat seal embossing, and the products have the following defects:
1. the finger can be damaged by digging;
2. the picture is single and can not be customized at will;
3. the specification is fixed;
4. heavy smell and no environmental protection;
5. the corner part is not bendable;
6. the oxidation resistance is poor, and yellowing resistance is not achieved;
7. the whole material is too hard due to non-fireproof and flame-retardant properties and poor elasticity;
8. the surface film is easy to peel and can not be perfectly connected;
9. the back surface has no self-adhesive, and the self-adhesion is difficult to pave;
10. the surface has raised grains and the like.
Many of the above problems exist with playground child-resistant products, which do not meet the standards of use, and therefore, some project merchants do not use the current market protection boards: some of the methods use advertisement backing gummed paper to adhere to the wood board, some use fire-proof board, some use lamp box advertisement cloth to adhere to the wood board, etc., however, these methods have serious safety hazard! Some manufacturers use soft package colored drawing PVC, and the nail is on the plank, acts as the guard plate, so, can solve the safety problem to a certain extent, however the cost is high, because open the plank earlier, spout universal glue again to the plank on, paste the pearl cotton after that, draw the leather to go up the nail with colored drawing PVC at last, the process is various, and production shipment speed is slow, often appears the goods to the place after, discovery size during the installation closes on, easy reworking etc..
Disclosure of Invention
In view of the above, there is a need to provide a protection plate and a preparation method thereof, the protection plate is mainly applied to the amusement park industry of children, and the protection plate has the advantages of personalized customization of pictures, arbitrary customization of specifications, scratch resistance, wear resistance, yellowing resistance, environmental protection, no odor, bending at corners, fire resistance, flame retardance, high anti-collision resilience, no peeling on picture surfaces, quick self-adhesion and paving of composite adhesive sticker on back surfaces, and the like. Thereby greatly improving the protection level and the use time of the children!
The invention adopts the following technical scheme:
the protection plate of the invention comprises: one deck coiled material on one deck foam cotton and the foam cotton, the surface of coiled material is through gloss oil drenching membrane solidification, the cotton thickness of foam is 1 ~ 50mm, the thickness of coiled material is 0.1 ~ 0.9mm, the compound non-setting adhesive in the cotton back of foam so that the self-adhesion installation.
As one preferable scheme, the coiled material is PVC, PU, a ceiling soft film, artificial leather, cloth or a thin film and the like.
As a preferred scheme, the PVC is net-sandwiched PVC. If net clamping: 400D.
As one preferable scheme, the thickness of the foam cotton is 1-19 mm, and the thickness of the coiled material is 0.1-0.8 mm.
As a preferable scheme, the thickness of the foam cotton is 10mm, and the thickness of the coiled material is 0.35 mm.
As one preferable scheme, the foam cotton is high-density foam cotton (for example, the selected foam cotton has the density of 30 +/-2 Kg/m3Hardness 90 +/-10 degrees, air holes 70 +/-5 PPI, tensile strength 0.2 +/-0.02 MPa and elongation 113 +/-5 percent).
In the past, PU soft leather is adopted for ink jet printing, and the surface of PU soft leather is not provided with an ink absorption coating, so that the printed picture has poor effect, mainly the picture is whitish, the picture is deep and shallow, and the PU material is too soft, equipment often hits a spray head to cause the spray head to be scrapped, and the production cost is extremely high.
Aiming at the problem that color fading is easy to occur to colored drawing PVC, PU, soft ceiling membrane, artificial leather, cloth or thin film and the like, the surface of the material such as the PVC, PU, soft ceiling membrane, artificial leather, cloth or thin film which is sprayed and printed is subjected to surface film spraying and curing through film spraying equipment, and pictures such as the colored drawing PVC, PU, soft ceiling membrane, artificial leather, cloth or thin film and the like are protected by a gloss oil protective layer, so that the purposes of wear resistance, scratch resistance, yellowing resistance, environmental protection, no odor, handfeel and the like are enhanced, and the problem that color fading is easy to occur to color drawing PVC and the like is thoroughly solved.
The preparation method of the protection plate comprises the following steps:
s1, carrying out jet printing on the surface of the coiled material;
s2, performing film spraying treatment on the surface of the coiled material spray printing by adopting gloss oil;
s3, drying and curing the laminated coiled material;
s4, cooling and forming the coiled material obtained in the S3;
s5, compounding the coiled material subjected to the step S4 with foam cotton;
and S6, compounding the foam cotton and the adhesive sticker obtained in the step S5 to obtain the protection plate.
Further, in step S2, a lamination is performed by using an oil passing machine. The oil filter is a knife-scraping film coating device or a roller coating device.
Preferably, the film is sprayed by adopting a knife-scraping film spraying device, the production speed of the device is 3-8 m/min, and the thickness of the film is 40-70 g/m2The thickness of the sprayed protective film is uniform and has a grade; most preferably, the production speed of the equipment for scraping and laminating the film is 5 m/min, and the thickness of the laminated film is 50 g/m2。
The coating is carried out by adopting a roller coating device, the production speed of the device is 5-15 m/min, and the thickness of the coating is 25-55 g/m2Thickness of protective film sprayed by roller coating equipmentNon-uniform and poor quality; most preferably, the production speed of the equipment for coating the laminated film by the roller is 10 m/min, and the thickness of the laminated film is 30 g/m2。
Further, the curing and drying in step S3 is to perform curing and drying in an oven, wherein the oven temperature is 90 ℃ to 120 ℃, and the curing time is 2 minutes to 10 minutes.
Further, the bonding method in step S5 is to use a three-in-one compound machine for compounding.
The manually sprayed glue is uneven in thickness, low in viscosity of a thin position and not firm in adhesion, and foam is easy to corrode and collapse in a thick glue spraying place, so that the smell is heavy and environment-friendly, and the composition is not up to the standard. Consequently, this application changes to carry out full automatization laminating production with trinity compounding machine.
Further, the compounding temperature that trinity compounding machine goes on is 140 ~ 160 ℃.
Further, the bonding speed is 450-550 m/h; the dosage of the water-based crosslinking agent is 80-120 g/m2(ii) a The bonding pressure is N40-N60.
