Description
Technical Field
The invention relates to the technical field of PP decorative films, in particular to a flame-retardant and degradable PP decorative film and a preparation method thereof.
Background
With the continuous development of economic construction in China and the continuous improvement of the living standard of people, people have higher requirements on environment protection, beauty, comfort and other functions of decoration materials.
The decorative film is an important indoor decorative material, mainly comprises a polyvinyl chloride (PVC) decorative film, a Polyethylene (PE) decorative film, a polypropylene (PP) decorative film, a Polyester (PET) decorative film, a composite decorative film and the like, has good wear resistance and corrosion resistance, can isolate water, can play a role in surface protection and surface decoration, can effectively reduce the formaldehyde release amount in an artificial board substrate, is an ideal artificial surface decorative material, and can be widely applied to various fields of furniture, floors, wood doors, wall surfaces and the like.
At present, the decorative film is most widely applied as a PVC decorative film, but with the increasing importance of people on the environmental protection performance of materials, the PP decorative film with more remarkable environmental protection advantages gradually becomes a market hotspot. The PP decorative film is used as a surface finishing material, has natural appearance, vivid texture, no formaldehyde and more excellent surface performance, is a real environment-friendly finishing material, and can be widely applied to the finishing of medium density fiberboard, shaving board, plywood, stone-plastic board, metal board, calcium silicate board and other boards.
However, the PP decorative film is a high molecular material, has a low oxygen index, and is limited in its application range by the easy-to-burn property in air. In addition, the PP decorative film has low degradability, cannot be degraded in a short time after being subjected to landfill treatment, and causes certain pressure on environmental protection and land use.
Therefore, how to develop a flame-retardant and degradable PP decorative film is a problem which needs to be solved urgently by the technical personnel in the field.
Disclosure of Invention
In view of the above, the present invention aims to provide a flame retardant and degradable PP decorative film and a preparation method thereof, so as to solve the defects in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme:
a flame-retardant and degradable PP decorative film comprises the following raw materials in parts by weight: 60-90 parts of PP resin, 20-30 parts of filler, 10-20 parts of halogen-free flame retardant and 10-20 parts of degradation agent; wherein the PP resin is random copolymer PP resin and block copolymer PP resin.
Further, the ethylene content in the random copolymerization PP resin is 10-30 percent; the ethylene content in the block copolymerization PP resin is 10-30%.
The further technical scheme has the beneficial effects that the random copolymerization PP resin and the block copolymerization PP resin are compounded, so that the obtained PP resin has the advantages of high strength, high rigidity, good heat resistance, good dimensional stability, good processability and excellent low-temperature toughness.
Further, the filler is at least one of nano titanium dioxide, nano silicon dioxide and color master batch.
The further technical scheme has the beneficial effects that the filler selected by the invention can improve the dimensional stability and rigidity of the PP decorative film, improve the utilization rate of raw materials, reduce the production cost of the PP decorative film and simultaneously expand the application range of the PP decorative film.
Further, the halogen-free flame retardant is prepared by mixing 3-6 parts of calcium alginate, 3-6 parts of ammonium polyphosphate and 4-8 parts of nano organic montmorillonite.
The technical scheme has the beneficial effects that the flame retardant effect of the halogen-free flame retardant is realized by coating ammonium polyphosphate with calcium alginate gel and modifying nano organic montmorillonite. The calcium alginate has a good flame-retardant effect and a gel effect, can completely coat the ammonium polyphosphate powder, prevents the ammonium polyphosphate powder from reducing the mechanical property of the material due to moisture absorption in a polypropylene matrix, greatly influences the mechanical property of the material due to the addition of a common halogen-free flame retardant, can obviously reduce the combustion heat value of the material due to the addition of nano particles, and can also improve the mechanical property of the material. The synergistic effect of the intumescent halogen-free flame retardant and the nano organic montmorillonite has good thermal stability and char formation, the formed carbon layer has higher densification degree in the combustion process, and the flame retardant property and the heat resistance of the PP are improved more obviously. Meanwhile, the ammonium polyphosphate causes incomplete combustion of the material while inhibiting combustion, so that CO gas is released, and the release amount of CO in smoke is obviously reduced after the nano organic montmorillonite is added, thereby indicating that the organic montmorillonite has certain effects of inhibiting smoke and reducing toxicity in a flame-retardant system.
Further, the degradation agent is at least one of polylactic acid, polycarbonate and plant cellulose.
The further technical scheme has the beneficial effects that the selected degradation agent contains carbonyl, hydroxyl and other polysaccharide groups, is used as a food source of microorganisms, is favorable for the survival and propagation of the microorganisms, can be corroded and broken by the microorganisms during landfill, and finally decomposes the PP decorative film into CO2And water.
A preparation method of a flame-retardant and degradable PP decorative film specifically comprises the following steps:
(1) weighing the raw materials according to the parts by weight of the flame-retardant and degradable PP decorative film;
(2) mixing PP resin, filler, halogen-free flame retardant and degrading agent, heating and stirring, banburying, filtering, rolling by four rollers, embossing the mirror surface once, carrying out the mirror surface non-stick laminating process, cooling and coiling to obtain the flame-retardant and degradable PP decorative film.
Further, in the step (2), the temperature for heating and stirring is 70-100 ℃, the rotating speed is 200-; the banburying temperature is 160-170 ℃, and the banburying time is 1-2 h; the temperature of the filtration is 120-130 ℃.
Further, in the step (2), the temperature of the four-roll calendering is 175 ℃ and 185 ℃, and the speed is 35-45 m/min.
Further, in the step (2), the temperature of the mirror surface non-stick pasting process is 95-105 ℃, the peeling load is 60-80cN/5cm, and the speed is 12-18 m/min.
According to the technical scheme, compared with the prior art, the invention has the following beneficial effects:
the PP decorative film disclosed by the invention has excellent performances of high efficiency, flame retardance, good strength, good dimensional stability and the like, can trigger biodegradation after being discarded and buried, and is green and environment-friendly.
