Formula for producing highway signboard

Abstract

The invention relate to that technical field of billboard templates, and in particular relates to a formula for producing a highway signboard, the formula comprises the following raw material in partsby weight: 100-120 parts of PVC resin, 20-30 parts of calcium carbonate, 10-20 parts of recycled materials, 2-4 parts of a stabilizing agent, 0.4-0.6 part of PE wax, 0.5-0.7 part of stearic acid, 3-5parts of CPE, 2-4 parts of a reinforcing agent, 0.3-0.5 part of a plasticizer, 0.1-0.3 part of a fluorescent agent, 0.1-0.3 part of a luminescent agent, 0.1-0. 3 part of a mold release agent and 1-3parts of an antistatic agent. The formula is used for producing the highway signboard, and the highway signboard can be installed for a long time in places such as expressways and the like exposed outside without shade, can accept strong wind impact, can resist sunlight exposure, can have a fire prevention effect, and can be externally coated with paint.

Description

technical field [0001] The invention relates to the technical field of billboard templates, in particular to a production formula for road signboards. Background technique [0002] As we all know, the materials used by billboards on highways are roughly divided into steel, wood and plastic products. Steel formwork is widely used in many large-scale projects and has become the current mainstream formwork. However, steel formwork is subject to certain restrictions in use due to its weight, time-consuming and labor-intensive handling, and other reasons. At the same time, the production process of steel formwork is cumbersome, and there are many formwork accessories. Development needs to consume iron ore resources, and smelting will cause certain pollution to the surrounding environment. [0003] Wooden material formwork mainly refers to traditional wood formwork and plywood formwork. Wooden formwork has been gradually replaced by clad plywood formwork due to its own disadvan...

Problems solved by technology

[0005] This application provides a formula for the production of road signboards, which is used to solve the problem of poor formula of road signboards in the prior art, which leads to certain deficiencies in impact resistance, high temperature resistance, fire resistance, coating adhesion and strength properties , cannot be used for a long time and needs to be replaced frequently to increase the cost
