Problems solved by technology

[0025] 1) The price of the manufacturing equipment is low, the appearance of the produced traffic road signs is rough, it is difficult to restore the original shape after being bent, and the fragments are brought out after being broken, resulting in a low safety factor, and the production environment is poor and the production efficiency is low;
[0026] 2) If the price of manufacturing equipment is high, satisfactory products can be produced, but the manufacturing cost is high, and the cost of the product is also high, which affects the market share

Embodiment Construction

[0044] First, polyvinyl chloride is used as the main body, and the copolymer of acrylonitrile, butadiene and styrene and the copolymer modifier of methyl methacrylate, butadiene and styrene are added according to the addition amount of 25%, and the modifier is added according to 2%. Adding bisamide and barium stearate processing aids to prepare JPRUD polymer hybrid materials.

[0045] Make the following modifications to the blow molding machine:

[0046] a. The barrel and screw inside the blow molding machine are chrome-plated and anti-corrosion treated. When using JPRUD polymer composite materials, the service life of the machine can still be maintained during heat processing.

[0047] b. The barrel mouth is equipped with a special forced feeding device. From the feed port, a rifling structure is added, which can act as a forced feeding function when processing powder materials, and improves the phenomenon that general blow molding machines have poor pre-molding effects on p...

Abstract

This invention is a method of traffic in the manufacturing field, the safety and traffic signs described in the invention, whose road signs physical polymer mixed materials used JPRUD Blow Molding, and the gap in the base for adding achieve the required weight of the rubber. This invention produces in 180 dec bending, 15 seconds of the restitution, while ensuring that products in the crash, RCC, no debris flying, very high security. At the same time ,it is clearly a low integrated cost, a high cost-effective , security and traffic signs.

Description

technical field [0001] The invention belongs to the field of manufacturing methods of traffic road signs. Background technique [0002] Traffic road signs are a kind of road traffic safety facilities, which mainly play the role of warning, isolation and guidance. The road signs with reflective film sleeves have excellent warning and guiding functions no matter in the day or night, which greatly improves the traffic safety. driving safety. [0003] In foreign countries, especially in developed countries, traffic road signs have been widely used. In China, with the rapid development of highway construction, especially the completion and opening of a large number of high-grade highways, the development, production and application of traffic facilities including traffic signs are developing at an alarming speed. According to market information, the current national production and sales of cone-shaped traffic signs has exceeded 1.5 million per year, and column-shaped traffic si...
