Abstract

The present invention relates to a kind of is the plastic baling band for heavy package that is suitable for the heavy wares bundle and package that primary raw material is made through conventional production process with acrylic resin and modified materials thereof, evenly be shaped on convax diamond on its surperficial two sides, the place, both sides of the edge is shaped on the line fringe, to increase friction force and to tie up tightness, product is reeled and is constituted the disc of 400-500mm, owing to adopt material modified and technology, this product has very strong tensile strength and returns tension force, except that can the alternative metals strap, also have anticorrosion and antifouling, safe and reliable, easy and simple to handle, advantage such as cost is low.

Description

Plastic baling band for heavy package

It is primary raw material with polypropylene, calcium carbonate etc. that patent of the present invention relates to a kind of, and the heavy stretching resistance object that is used for that adopts conventional manufacture technology to make is tied up the plastic baling band for heavy package of occasion with the alternative metals strap.

In the cargo transfer process, most of object need be tied up, as Cotton and Linen, plastic knitting product, fine hair, hide and various containers etc., especially in the packaging process of exported product, adopt high-quality strapping attractive in appearance even more important, the power that rises again after above-mentioned article packing is tied up is bigger, and requiring strap to have very high tension intensity and tie up the knot place has bigger bundle power and friction force.At present the strap that uses mainly contains two classes, and the one, be used for light packaged plastic baling band, the 2nd, be used for the metal baling strip of heavy wares enlacement packaging.Existing plastic baling band is because its structure and material proportioning, and its tensile strength is very little, generally have only about 150 kilograms, and it is easily loosening and skid to tie up the knot place, so can only be applicable to tying up and packing of light matter spare.Metal baling strip has stronger tensile strength, can be used for heavy wrapping, but uses the refined steel material, need import, this steel strap fragility is big, poor toughness, easy fracture is hurted sb.'s feelings during use, and the steel strap dirty cargo that easily gets rusty, colliding when transportation and loading and unloading causes and causes fire by spark, safety hazard is arranged during use, the steel strap is in Kai Bao and also difficulty relatively when unhitching, cost height when manufacturing, complex process and wayward technical index.

The goal of the invention of patent of the present invention is to overcome existing heavy wrapping object, and to tie up the fragility that the steel strap that adopted exists big, poor toughness and uneasy congruent shortcoming, seek to manufacture and design and a kind ofly can the instead of steel strap tie up heavy wares and anti-corrosive properties is good, dirty cargo not, the tensile strength and the power that rises again all meet the requirements, it is low to manufacture cost, ties up plastic baling band for heavy package easily.

To achieve these goals, it is primary raw material that patent of the present invention adopts polypropylene, mix an amount of ground calcium carbonate, titanate coupling agent and lubricant etc. according to suitable proportioning and dose material, make the tep reel shape strip type heavy wrapping plastic baling band of disc type packaging structure by required production technology and equipment.The bandwidth of this strap is 15～26mm, and thickness is 1.2～1.6mm, and length is optional, and the place, surperficial both sides of the edge of band is shaped on the line fringe, evenly is shaped on the thick convax diamond of 0.1～0.5mm on the two sides.During use, get from the tep reel outer end and to take the lead, the intercepting Len req utilizes specialized equipment tension strap to tie up by the bundle object, with the metal clasp of autocracy the strap two ends is tightened up to get final product again.

Patent of the present invention compares with existing strap that to have a tensile strength big, good toughness, damp proof antiseptic property is superior, the power that rises again is strong, and manufacture technology is easy, and cost is low, aesthetic in appearance, safe and reliable, easy fracture and outstanding advantage such as skid not are to substitute the ideal product that present heavy wares packing is tied up the steel strap of usefulness.

Fig. 2 is a patent tep reel structural representation of the present invention,

Fig. 3 ties up the use scheme drawing for patent of the present invention.

The enforcement of patent of the present invention mainly branch raw material preparing, plasticizing extrude, once traction typing, the heating of hot drying tunnel, secondary drawing-off, embossing and roll seven technological processes such as finished product.The raw-material proportioning of choosing is: 75 kilograms of PP resins, 12.5 kilograms of modified materials, 30 kilograms of color masterbatches etc.Modified materials mainly is acrylic resin MI2-3, white free from admixture and moisture are less than 0.3%, the order number is 300 ground calcium carbonate, titanate coupling agent and other lubricants, calcium carbonate is put into kneader be heated to 80 ℃, remove and to add 0.3～0.5% coupling agent behind the moisture and make activated calcium carbonate, the proportioning of modified materials is: PP resin 60～70%, activated calcium carbonate 30～40%, 200～300 milliliters/100 kilograms of White Mineral Oils.By raw material ratio with needed raw material add stir 5～10 minutes in the kneader after, utilize the extruder extruding pelletization, its particle specification is φ 3 * 3mm.Utilize 65 type extruders to finish plasticizing and extrude, its expressing technique temperature is: 190～210 ℃ of die heads, 180～200 ℃ of feed zones, 240～250 ℃ of fluxing zones, 240～250 ℃ of metering sections.Utilize the water typing mode of 30～35 ℃ of water temperatures once to draw, its speed can be according to extrusion capacity and product specification adjustment.Because the sectional area of plastic baling band for heavy package is bigger, be generally 1.5 * 19～25mm, for obtaining higher draft temperature, when the typing of heating stretch orientation, adopt hot drying tunnel type of heating.When utilizing drafting assembly to carry out draw forming, choosing draft ratio is 7～9 times.Patented product of the present invention is in the embossed technology process, adopt conventional emebosser, at width 19～26mm, thickness 1.2～1.6mm, length is shaped on decorative pattern on the base band surface arbitrarily, promptly is shaped on wide 0.5～1.0mm, the line fringe 1 of thick 0.1～0.5mm on the edge, two sides of band, evenly be suppressed with the convax diamond 2 of thick 0.1～0.5mm between the line fringe 1 of two sides, matrix strain line 3 is arranged between its convax diamond.The product tape that is shaped on decorative pattern is wound into circular tep reel 4, and the external diameter of its tep reel 4 is 400～500mm, and thickness 100～150mm seals the use of can dispatching from the factory with the bundle of the two ends on the tep reel.The strap of intercepting suitable length during use is buckled in two belt ends on its crosspiece 6 with special-purpose metal clasp 5 that knot is solid lives being taken up the back on the object by being tied of mechanical pressing, and the two ends reservation is pressed in by being tied object one side greater than the length of 100mm just can.
