Preparation method of double-color thermal shrinkage pipe, product thereof and LED double-color straight lamp

Abstract

The invention discloses a preparation method of a double-color thermal shrinkage pipe. The preparation method comprises the following steps: (1) a double-color extrusion forming machine is prepared; (2) a color-A PET glue material and a color-B PET glue material are respectively put in different host machine cylinders to form a molten state; (3) the color-A PET glue material and the color-B PET glue material in the molten state are added in the double-color extrusion forming machine; and (4) the color-A PET glue material and the color-B PET glue material are respectively fed in a runner mechanism, a distributor and a discharge round gap of a forming mold in sequence for extrusion, ventilation and drying to form the double-color thermal shrinkage pipe. The invention further discloses the double-color thermal shrinkage pipe prepared by the method; and the double-color thermal shrinkage pipe has such advantages as low production cost, easy identification, convenient installation, illumination reinforcement, energy conservation, consumption reduction and overall beauty. At the same time, the invention further discloses an LED double-color straight lamp based on the double-color thermal shrinkage pipe; and such performances as illuminance and safety are obviously improved.

Description

Technical field [0001] The invention relates to the field of lighting, in particular to a method for preparing a two-color heat shrinkable tube, its products and an LED two-color straight lamp. Background technique [0002] Heat shrinkable tube is a kind of soft tube that will gradually shrink when heated to more than 30 degrees. It is widely used in insulation protection of various batteries, inductors, capacitors, etc., as well as rust prevention, corrosion prevention, and packaging of special parts. . The material of the heat shrinkable tube is mainly plastic, but the traditional single-color heat shrinkable tube has many defects when it is applied to the glass lamp tube and some special industries. [0003] The LED glass tube two-color straight lamp is mainly composed of a straight glass tube and a substrate installed in the glass tube and LED lamp beads. Since the LED lamp beads are point light sources, the light emitted is very dazzling. In order to make the light source a m...

AI Technical Summary

Problems solved by technology

[0014] a. The glass tube is easy to break in actual use, and it is easy to cause harm to people and objects;

[0015] b. The sheet diaphragm is not easy to install, labor-intensive and time-consuming, resulting in a lot of waste;

[0016] c. A card slot is set in the glass tube, resulting in an increase in the cost of the glass tube;

[0017] d. The aluminum strip substrate and the sheet diaphragm cannot be in close contact, and there is no reflective material in the backlight part, which leads to waste of some light sources and affects the light intensity;

[0018] e. The place where the aluminum strip substrate in the glass tube is in contact with the glass is too exposed, which affects the look and feel

[0019] The industry also uses PC lampshade technology. Due to the high cost of raw materials, it may be deformed and bent after long-term use. It is also difficult to survive in today's fierce market competition.
