Problems solved by technology

In fact, the road guardrail is an indispensable device for road traffic. The surface of the guardrail needs to be sprayed with these paints. The paint is more conspicuous and easy for traffic participants to identify. Moreover, the guardrail is in a natural environment, and its surface is prone to rust under the wind and sun. , also needs anti-rust treatment, the current spraying equipment is inefficient, and the waste of paint is large, which is not conducive to environmental protection

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0029] A guardrail surface spraying method includes the following steps: spraying hot-dip galvanizing on the base layer, and secondly spraying thermoplastic powder coating, wherein the hot-dip galvanizing layer on the surface can play the role of antirust and anticorrosion.

[0030]A new type of coating, specifically a formulation of guardrail surface spraying material (thermoplastic powder coating): it is made of the following raw materials in parts by weight: 15-25 parts of thermosetting acrylic resin, 10-12 parts of aromatic hydrocarbon modified terpene resin , 3-6 parts of bismaleimide resin, 0.3-0.8 parts of dilauryl thiodipropionate, 2-4 parts of hydrogenated ro...

Abstract

The invention relates to the technical field of guardrail surface spraying, in particular to guardrail surface spraying equipment. The equipment executes the following spraying method that hot galvanizing is sprayed on the bottommost layer, then thermoplastic powder coating is sprayed, and the hot galvanizing layer on the surface can play a role in rust prevention and corrosion prevention. Wherein the sprayed novel coating is a thermoplastic powder coating, and the thermoplastic powder coating can prevent the coating from being pulverized and falling off. The guardrail surface spraying equipment comprises the first supporting leg and the second supporting leg, the first supporting leg and the second supporting leg are connected into a whole through the connecting plate, clamping of a guardrail is changed into clamping through the arc face of the clamping wheel, in this way, the area covered by the clamping face can be exposed for spraying, spraying dead angles are avoided, and the spraying efficiency is improved. And the change of the clamping direction is realized in a rolling manner, so that the sprayed surface of the guardrail can be prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of guardrail spraying, in particular to guardrail surface spraying equipment. Background technique [0002] Air pollution and rain erosion have brought serious erosion to the guardrails of structures such as roads, bridges and municipal facilities, affecting their aesthetics, functionality and durability. Traditional coatings generally have disadvantages such as poor stain resistance, poor corrosion resistance, and easy peeling, which restrict their application to a certain extent. In order to improve, new coatings can be used to improve, for example, a surface anti-corrosion nano-coating with high weather resistance, high wear resistance and high corrosion resistance, which can effectively meet the long-term anti-chloride ion penetration of steel, Anti-biological erosion, anti-corrosion and other requirements, the nano-coating is suitable for all kinds of steel structure surfaces, including steel structure...
