Description
Technical Field
The invention relates to the technical field of PP belts, in particular to a high-tension PP belt and a preparation method thereof.
Background
PP strapping bands, known as polypropylene, are lighter of common plastics and have been widely used in various fields, PP represents polypropylene, polypropylene grades are many, a polypropylene raw material with a grade of T30S is used for strapping band production (best effect), and PP strapping band appearance: translucent to opaque, clear textured films. Combustibility: and is combustible in a flame. Slowly extinguish or continue burning after leaving the flame, wherein the upper end of the flame is yellow and the lower end is blue during burning; have melting, the drippage phenomenon, can smell the paraffin taste, but current PP takes holistic tensile ability relatively poor, produce the fracture under high tensile force very easily, thereby lead to the packing not tight enough, the later stage produces the emergence of loose phenomenon, it is exactly that holistic anticorrosive and anti flame retardant ability is on the low side in addition, under meetting the high corrosive environment, very easy rapid ageing, then produce the fracture, lead to the packing effect general, and produce the burning very easily under meetting the naked light condition, thereby produce the conflagration, bring certain potential safety hazard.
Technical problem to be solved
Aiming at the defects of the prior art, the invention provides a high-tension PP belt and a preparation method thereof, and solves the problems that the existing PP belt is poor in overall tensile strength and easy to break under high-tension force, so that the packing is not tight enough, the overall anti-corrosion and anti-flame performance is low, the PP belt is easy to age quickly under a high-corrosion environment, and the PP belt is easy to burn under an open fire condition.
(II) technical scheme
In order to achieve the purpose, the invention provides the following technical scheme: a high-tensile PP belt is prepared from the following raw materials in parts by weight: 100-120 parts of polypropylene particles, 50-60 parts of wire-drawing-grade resin, 20-25 parts of anti-flame-retardant colloidal particles, 8-12 parts of anti-corrosion colloidal particles, 15-20 parts of hot-melt adhesive reinforcing materials and 5-10 parts of pigment blenders.
In a preferred embodiment of the present invention, the pigment blending agent is classified into a fat-soluble pigment blending agent and a water-soluble pigment blending agent, and the pigment blending agent is one or a mixture of more of chlorophyll, lutein, crocin, anthoxanthin, anthocyanin and catechin.
As a preferable technical scheme of the invention, the antiseptic colloidal particles are one or more selected from sodium lactate particles, calcium propionate particles, dehydroacetic acid particles, sorbic acid and benzoic acid particles.
As a preferable technical scheme of the invention, the anti-flame-retardant colloidal particles are made of PC polycarbonate material, and the main component of the wire-drawing-grade resin is polypropylene material.
As a preferable technical scheme of the invention, the hot-melt adhesive reinforcing material is fibrous or powdery, and the particle diameter is between 8 and 14 mm.
The invention also provides a manufacturing method of the high-tension PP belt, which comprises the following steps:
s1, placing the polypropylene particles, the wire-drawing-grade resin, the anti-flame-retardant colloidal particles and the anti-corrosion colloidal particles into a high-temperature box for high-temperature melting, then taking out the polypropylene particles, the wire-drawing-grade resin, the anti-flame-retardant colloidal particles and the anti-corrosion colloidal particles for later use, then pouring the hot-melt adhesive reinforcing material and the pigment blender into the box, and stirring the mixture by using a stirrer to obtain a;
s2, standing the molten mixture for 2-6min, then pouring the molten mixture into an extruder, controlling the temperature of the extruder to be 250-280 ℃, then performing extrusion operation, and directly introducing the extruded finished product into cold water;
s3, preparing a container filled with clean water, cooling the clean water to boiling through a heater, and introducing an extrudate obtained in an extruder by using a special clamp;
s4, fixing and stretching the extrudate in boiling water by a stretching machine, controlling the stretching distance to be 4-10cm, and keeping the original shape for 10-15min after stretching;
and S5, taking out the stretched product, naturally drying, then winding by using a winding machine, and finally packaging by using a packaging machine to finish the final packaging work.
As a preferred technical scheme of the invention, the internal temperature of the high-temperature box in S1 is controlled at 260-290 ℃, and the high-temperature melting time in S1 is controlled at 18-25 min.
As a preferred technical scheme of the invention, the hot melt adhesive reinforcing material and the pigment blender in the S1 need to be correspondingly mixed before being poured, and the natural drying time in the S5 is controlled to be 5-10 min.
(III) advantageous effects
Compared with the prior art, the invention provides a high-tension PP belt and a preparation method thereof, and the high-tension PP belt has the following beneficial effects:
this high tension PP area and preparation method thereof, through adding wire drawing level resin, make whole PP area possess better tensile ability, thereby when needs fastening packing material, can accept the bigger pulling force of baling press, let the article after whole packing more firm, the fracture has been avoided producing under the too big pulling force, the whole practicality of PP area has been improved, anti fire-retardant micelle of rethread and anticorrosive micelle, let PP area can not produce the burning under the condition that meets naked light, the increase of the intensity of a fire has been avoided, the safety in utilization in PP area has been improved, also be under high corrosion environment, let PP area can better adaptation high strength corrosion, the fast ageing of producing under the strong corrosion state has been avoided, make packing material can obtain better packing.
