Abstract
The invention relates to a high-strength high-breathability polrvinyl chloride preservative film which comprises the following components in parts by weight: 100 parts of PVC resin (SG-4 type), 4-6 parts of calcium-zinc compound stabilizing agent, 0.5-1 part of stearic acid, 25-30 parts of dioctyl phthalate (DOP), 20-25 parts of 1,2-propylene glycol adipate, 2-5 parts of nano scale silicon dioxide (SiO2), 1-3 parts of silane coupling agent, 2-5 parts of nano scale calcium carbonate (CaCO3) and 1-3 parts of titanate coupling agent. The components are prepared into a film with a certain thickness through the working procedures of mediating, extruding, blow molding, and the like, and the film is used for retaining the freshness of agricultural products. The preservative film has the main technical characteristics that the tensile strength and the elongation at break of the preservative film are 10-30 percent higher than that of ordinary preservative films, the breathability rate is improved by 10-20 percent, and the preservative film has better packability to the agricultural products and good breathability and can effectively prevent frosting.
Description
Technical field
The invention belongs to fruit-vegetable plastic wrap, particularly a kind of high-strength height passes through wet SE preservative film.
Background technology
Existing SE preservative film, though fresh-keeping effect is fine, its physical strength is not really high, water vapour permeability is relatively poor, has influenced the SE preservative film like this and has used.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of high-strength height to pass through wet SE preservative film.High the passing through of HS wet its stretchiness, tear resistance, frictional coefficient, transmittance, the equal National standard of heat sealability.
Technical scheme of the present invention is:
A kind of high-strength height passes through wet SE preservative film, it is characterized in that:
It is filled a prescription by weight:
100 parts on PVC RESINS SG-4 type,
Calcium-zinc composite stabilizing agent 4-6 part,
Triple Pressed Stearic Acid 0.5-1 part,
DOP DOP25-30 part,
Polypropylene adipate(PPA) 20-25 part,
Nanometer grade silica SiO
22-5 part,
Silane coupling agent 4-10 part,
Nanometer grade calcium carbonate CaCO
32-5 part,
Titanate coupling agent 4-10 part.
Above component is used for agricultural products fresh-keeping through mediating, extrude, processing certain thickness film after the blowing operation.
Earlier inorganic nano lime carbonate is carried out modification in the processing:
Earlier with inorganic nano lime carbonate 110 ℃ of preheating and dryings 3 hours, remove moisture; Inorganic nano lime carbonate, titanate coupling agent, absolute ethyl alcohol are pressed 1: 2: 20 abundant dispersed with stirring of mass ratio, handle 30 minutes dry solvents of removing of final vacuum and make organic modified nano lime carbonate.
Inorganic nano silicon-dioxide is carried out modification
Inorganic nano grade silicon dioxide, silane coupling agent γ-(methacryloxypropyl) propyl trimethoxy silicane, toluene are pressed mass ratio fully to be disperseed at 1: 2: 15; Reaction for some time postcooling; Deposition is dry with absolute ethanol washing, obtains the nanometer grade silica of modification.
When mixing of materials:
With DOP with the abundant swelling of PVC RESINS after, add thermo-stabilizer (calcium-zinc composite stabilizing agent), polymeric plasticizer (polypropylene adipate(PPA)), organic modified nano lime carbonate, organically-modified nano-silica silicon, lubricant (Triple Pressed Stearic Acid) and mix.
Effect of the present invention is:
Tensile strength of this preservative film and elongation at break are all than the high 10%-30% of common preservative film, and rate of perviousness improves 10%-20%, and better to agricultural product packaging property, water vapour permeability is good, can prevent to tie mist effectively.This technology can significantly improve preservative film machinery intensity and water vapour permeability, technology is simple, product cost is lower.High-strength height of the present invention passes through the nanometer grade silica particle that adds in the wet PVC fresh-preserving film and can combine with macromolecular chain to form tridimensional network, and Nano particles of calcium carbonate is spherical rigid particles, and the two can improve the intensity of material; The structure porosity is high in the nano silicon, and nano-calcium carbonate can be introduced countless small defectives in the PVC film, and the preservative film water vapour permeability is increased.When fruits and vegetables were packed storage, it is good that high-strength height passes through wet SE preservative film water vapour permeability, and water vapour and ethylene gas are had the stronger adsorption and the ability of seeing through.
The main characteristic that this high-strength height passes through wet SE preservative film is that high the passing through of HS wet its stretchiness, tear resistance, frictional coefficient, transmittance, the equal National standard of heat sealability.
