Problems solved by technology

Open pipes can solve this problem, but because of the properties of the plastic itself, the opening of open plastic pipes is prone to deformation under high temperature or long-term aging, making the opening larger and larger, and losing the sealing effect on cables and wires , so it is necessary to provide a new sleeve and preparation process for the problem of plastic opening deformation of the opening

preparation example Construction

[0026] A kind of preparation technology of self-rolling plastics, is characterized in that, comprises the following steps:

[0027] Melt and mix 100 parts of plastic particles and 0.5-10 parts of flame retardant;

[0028] The mixed material is extruded into the spiral integrated mold through the extruder and extruded into shape, and the section of the outlet of the spiral integrated mold is a spiral disc structure;

[0029] It is then cooled to obtain the self-rolling plastic.

[0030] The mixing is completed in the mixer, and plastic particles are added into the mixer, and the flame retardant is mixed evenly. Then use an extruder to extrude the mixture into a screw integral mold for molding, and extrude to obtain a self-rolling plastic. The cross-section of the spiral one-piece mold is a spiral disk structure, so that the plastic can be shaped into a spiral roll shape.

[0031] preferred, such as figure 1 As shown, the spiral one-piece mold includes a first end portion 1,...

Embodiment 1

[0041] Mix 100 parts of PVC granules and 0.5 parts of aluminum hydroxide at 160°C for 2 minutes; after mixing evenly, extrude the mixture through a plastic extruder into a spiral integrated mold with a spiral disc structure in cross-section. The temperature of the extruded screw barrel is adjusted at 170°C, and the temperature of the spiral integrated mold is 60°C; after forming, it is blown to cool, and cooled to room temperature to obtain the finished self-rolling plastic. The obtained self-rolling plastic has the same shape as the forming mold, and the plastic is naturally rolled inward. When the opening is opened during use, it can be automatically rolled to the initial state after use. There is no obvious change in the gap between the spiral outer ring and the inner ring, and the automatic winding performance is strong.

Embodiment 2

[0043]Mix 100 parts of PC granules and 5 parts of brominated polystyrene at 230°C; after mixing evenly, extrude the mixture through a plastic extruder into a spiral integrated mold with a spiral disc structure in cross section; extrude The temperature of the extruded screw barrel is adjusted at 230°C, and the temperature of the spiral integrated mold is 80°C; after forming, it is blown to cool, and cooled to room temperature to obtain the finished self-rolling plastic. The obtained self-rolling plastic has the same shape as the forming mold, and the plastic is naturally rolled inward. When in use, it can be automatically rolled to the initial state after opening the opening and used. There is no obvious change in the gap between the spiral outer ring and the inner ring, and the automatic winding performance is strong.

Abstract

The invention discloses self-coiling plastic and a preparation process thereof. The preparation process comprises the following steps: mixing plastic particles and a flame retardant at high temperature; after material mixing is finished, extruding a formed mixture to a spiral integrated mold through an extruder for forming, wherein the section of a discharging opening of the spiral integrated mold is of a spiral disc type structure; and cooling the formed self-coiling plastic to room temperature to obtain the self-coiling plastic. The invention further provides the self-coiling plastic. According to the preparation process of the self-coiling plastic, the spiral integrated mold with the section of the discharging opening being of the spiral disc type structure is adopted for shaping, the technology is simple, applicability is high, and the prepared self-coiling plastic can keep mechanical performance for a long time and has high self-coiling capacity.

Description

technical field [0001] The invention relates to a self-rolling plastic and a preparation process thereof, belonging to the technical field of preparation of self-rolling materials. Background technique [0002] When using power transmission and electrical appliances and other equipment, wires, cables, etc. need to be used as wires. Too many wires and cables are messy and disorderly, and the exposed wires are easy to accelerate the aging and damage of the wires. Therefore, in order to make the messy, scattered wires and cables regular and relatively fixed, and to protect the exposed wires and cables , The cable is covered with a PVC pipe or other types of sleeves to cover and encapsulate the wires. [0003] For the wires and cables that have been packaged, once there is a line fault, it is often necessary to destroy the sleeve during maintenance to expose the fault point; and to cover the wires and cables in use, it is necessary to plan the sleeve and then remove it. Wires ...
