Problems solved by technology

At present, more studies on bags are about the structure of the box itself and the accessories such as wheels, for example, how to make it run more flexibly by changing the structure of the accessories under the load-bearing condition; There are few materials and preparations. The current preparation of the wheel itself is made of polypropylene (PP) as the main raw material after melting and injection molding. Although PP has the best heat resistance and good stress crack resistance, It also has a high bending fatigue life, but it also has disadvantages such as low dimensional accuracy, insufficient rigidity, poor weather resistance, and easy to produce "copper damage". In the application of luggage, it is characterized by small load and poor wear resistance

Embodiment 1

[0017] A preparation process for luggage wheels, comprising the following preparation steps:

[0018] Step A, 1 part of black smoke, 15 parts of organic red, 3 parts of bright yellow, 1 part of rose red and N.N'-1, 2-ethylenediyl dioctadecamide (320 mesh) 10 parts by weight The parts are mixed and evenly prepared to prepare the colorant;

[0019] Step B, pour the color material prepared in step A into a container containing plastic granules (PA), and stir for 3 minutes to obtain the raw material; according to the calculation by weight, the color material in the container is 30 parts, 25000 parts for plastic pellets;

[0020] Step C. After fully melting the raw materials obtained in step B at a high temperature of 200°C, injection molding (at a temperature of 210°C) is carried out to obtain a finished wheel.

Embodiment 2

[0022] A preparation process for luggage wheels, comprising the following preparation steps:

[0023] Step A, 10 parts by weight of black smoke, 5 parts of organic red, 10 parts of bright yellow, 10 parts of rose red and N.N'-1, 2-ethylenediyl dioctadecamide (350 mesh) 15 parts The parts are mixed and evenly prepared to prepare the colorant;

[0024] Step B, pour the color material prepared in step A into a container containing plastic granules (PA+PPU), and stir for 4 minutes to obtain raw materials; according to the calculation by weight, the color in the container The material is 50 parts, and the plastic pellet is 25000 parts;

[0025] Step C. After fully melting the raw materials obtained in step B at a high temperature of 220°C, injection molding (at a temperature of 215°C) is performed to obtain a finished wheel.

Embodiment 3

[0027] A preparation process for luggage wheels, comprising the following preparation steps:

[0028] Step A, 5 parts by weight of black smoke, 8 parts of organic red, 5 parts of bright yellow, 2 parts of rose red and N.N'-1, 2-ethylenediyl dioctadecamide (325 mesh) 30 The parts are mixed and evenly prepared to prepare the colorant;

[0029] Step B, pour the color material prepared in step A into a container containing plastic granules (PA+PPU), and stir for 6 minutes to obtain raw materials; according to the calculation by weight, the color in the container The material is 50 parts, and the plastic pellet is 25000 parts;

[0030] Step C. After fully melting the raw materials obtained in step B at a high temperature of 250°C, injection molding (at a temperature of 220°C) is carried out to obtain a finished wheel.

Abstract

The invention belongs to the technical field of case and bag preparation, and especially relates to a preparation technology of a case and bag wheel. PA, or PA and PPU are used as main materials, certain amounts of black smoke, organic red, brilliant yellow, rose-bengal and diffusion powder are also used, and the use amount of each raw material and the humidity, temperature and time in the production process are controlled. The technology has a simple process, and the produced wheel has the advantages of special bright color, strong gloss, nontoxic and odorless property, no color change or corrosion at 100 DEG C or below, and harmlessness to human bodies and objects, meets environmental protection standards, especially can bear much luggage, and has very good wear resistance.

Description

technical field [0001] The invention belongs to the technical field of luggage preparation, in particular to a process for preparing luggage wheels. Background technique [0002] As the main equipment for travel, luggage plays an extremely important role in the journey, and providing excellent protection for luggage is the first priority. Therefore, it is required not only to have capacity, but also to have functions such as safety, anti-extrusion, waterproof, and anti-collision. Among them, safety not only refers to the durability of the luggage material, but also refers to the durability of the handles, pull rods, pulleys and other components. Because most travelers use the luggage in a row, the wheels on the luggage are also very important. At present, more studies on bags are about the structure of the box itself and the accessories such as wheels, for example, how to make it run more flexibly by changing the structure of the accessories under the load-bearing conditio...
