Abstract
The invention discloses a mildew-proof and fresh-keeping plastic packaging material. The mildew-proof and fresh-keeping plastic packaging material is prepared from polyvinyl resin, nano antibacterial particles and a processing auxiliary agent, wherein according to the mass percent, the polyvinyl resin accounts for 91 percent to 94 percent, the nano antibacterial particles account for 2 percent to 6 percent and the processing auxiliary agent accounts for 3 percent to 6 percent; the nano antibacterial particles are nano titanium dioxide particles; the processing auxiliary agent is prepared from the following components in parts by mass: 30 to 35 parts of a coupling agent, 20 to 25 parts of a plasticizer, 8 to 10 parts of an antistatic agent, 2 to 6 parts of a stabilizer and 31 to 33 parts of a filling agent. With the adoption of the manner, the nano antibacterial particles with the reasonable ratio are added, so that the mildew-proof and fresh-keeping plastic packaging material has good bacterium-inhibition and mildew-proof effects, and also has good strength and a long service life.
Description
Technical field
The present invention relates to plastic package material field, particularly relate to a kind of anti-mildew fresh-keeping plastic package material.
Background technology
Plastics are widely used in daily life, all trades and professions and high-quality precision and sophisticated technology field because of its light weight, easily processing, the feature such as both artistic and practical, price is low.
Existing plastic package material is shorter for service life, on the one hand due to its intensity difference, cracky, after on the other hand using cycle length, it is raw that its surface often produces antibacterial evil, and barrier is poor, make surface bacteria penetrate in products to be packaged, thus cause products to be packaged mouldy, rotten.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of anti-mildew fresh-keeping plastic package material, is added with nano-antibacterial granule, has good bacteria mildew-proof effect, and intensity is good simultaneously, and service life is long.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of anti-mildew fresh-keeping plastic package material, including: polyvinyl resin, nano-antibacterial granule and processing aid, calculate by mass percentage, described polyvinyl resin accounts for 91%-94%, described nano-antibacterial granule accounts for 2%-6%, described processing aid accounts for 3%-6%, wherein said nano-antibacterial granule is titanium dioxide nanoparticle, described processing aid includes the composition of following mass parts: coupling agent 30-35 part, plasticizer 20-25 part, antistatic additive 8-10 part, stabilizer 2-6 part and filler 31-33 part.
In a preferred embodiment of the present invention, described filler is calcium titanate, calcium oxide, calcium sulfate calcium sulfite batch mixing.
In a preferred embodiment of the present invention, described stabilizer includes salicylate type ultraviolet light stabilizer and organo-tin compound type thermal stabilizing agent.
In a preferred embodiment of the present invention, the particle diameter of described nano-antibacterial granule is 10-30nm.
The invention has the beneficial effects as follows: by adding nano-antibacterial granule, optimize polyvinyl resin, nano-antibacterial granule and the proportioning of processing aid, optimize composition and the proportioning of processing aid simultaneously, the anti-mildew fresh-keeping plastic package material prepared is made to have good bacteria mildew-proof effect, intensity is good simultaneously, and service life is long.
