Example Embodiment

[0069] Example 1

[0070] In the present embodiment, the production method of the ton bag is carried out according to the following steps:

[0071] (1) Stirring: the raw materials and the filling master batch are mixed according to a weight ratio of 9:1, and stirred evenly to obtain mixed raw materials. The filler masterbatch includes the following components:

[0072] 80 parts by weight of calcium carbonate;

[0073] 5 parts by weight of dispersant, which is made up of paraffin wax and fatty acid polyethylene glycol ester in a ratio of 1:0.5 by weight;

[0074] 6 parts by weight of plasticizer, the plasticizer is composed of dioctyl phthalate and glycol fatty acid ester in a weight ratio of 1:2;

[0075] 2 parts by weight of color masterbatch;

[0076] The reinforcing agent is 3 parts by weight, and the reinforcing agent is composed of cyanoethyl cellulose and ethoxyamidobenzyl in a weight ratio of 1:1.

[0077] (2) Hot-melting: heating the mixed raw materials to 220° C....

Abstract

The invention provides a ton bag production method which comprises the steps of stirring, hot melting, cooling, wiredrawing, rolling, weaving, cutting, printing and sewing, specifically, raw materials and filling master batches are mixed according to the weight ratio of (9-19): 1, and mixed raw materials are obtained; heating the mixed raw material to 220-270 DEG C for hot melting, and extruding to obtain a film; feeding the film into a cooling water tank, and shaping under the action of circulating cooling water; the cooled film is cut to form blank filaments, then the blank filaments are stretched and shaped to form flat filaments, and the flat filaments are processed into the cylindrical woven bag and the hanging shroud band of the corresponding size through a circular weaving machine. Production of the ton bag is achieved, the tensile strength and flatness of the ton bag are improved, and meanwhile the ton bag has good falling performance and low elongation.

Description

technical field [0001] The present application relates to the technical field of big bags, in particular to a production method of big bags. Background technique [0002] Ton bags, also known as container bags, are made of polypropylene and polyethylene resin as the main raw materials, with a small amount of auxiliary materials added, mixed and melted by an extruder, extruded plastic film and cut into billets, which are processed at a temperature lower than the melting temperature of the resin. Stretching, making high-strength, low-elongation flat yarn through molecular orientation and heat setting, and then making woven bags through winding, weaving, cutting and sewing. The ton bag has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe. It is a flexible transportation packaging container that can be widely used in various powdery, granular and blocky items such as chemicals, building materials, plastics, and mineral products. , transportation ...
