Problems solved by technology

The above scheme realizes the anti-corrosion treatment of the fence through rust removal, painting and wrapping heat shrinkable film to prolong the service life of the fence; Exposure to light, heavy rain, and long-term exposure to the sun and rain will cause blistering and peeling of the heat shrinkable film wrapped on the surface of the fence. In severe cases, white rust or red rust will appear on the surface of the fence, and the product has poor moisture and heat resistance. And poor corrosion resistance

Embodiment 1

[0039] The production process of composite fence for residential use includes the following steps:

[0040] In step 1, the workpiece is placed in an activation solution for activation treatment at 40° C. for 25 minutes to obtain an activated workpiece; the activation solution includes hydroxyalkylphenol polyoxyethylene ether and aminosilane coupling agent with a mass ratio of 2:0.7 ;

[0041]In step 2, a modified glue solution is applied to the surface of the activated workpiece, and a modified film of 100 μm is formed on the surface to obtain a modified workpiece; the modified glue solution is prepared through the following steps: heating the epoxy resin to 110° C. Based on epoxy resin, trilauryl phosphite was added according to 0.9wt%, zirconium oxychloride was added according to 0.1wt%, and borax was added according to 0.2wt%; vacuum heating and positive pressure heating were used to alternately react twice, vacuum heating One cycle of heating and positive pressure heating...

Embodiment 2

[0045] The production process of composite fence for residential use includes the following steps:

[0046] In step 1, the workpiece is placed in an activation solution for activation treatment at 55° C. for 18 minutes to obtain an activated workpiece; the activation solution includes hydroxyalkylphenol polyoxyethylene ether and aminosilane coupling agent with a mass ratio of 4:0.7 ;

[0047] In step 2, a modified glue solution is applied to the surface of the activated workpiece, and a modified film of 100 μm is formed on the surface to obtain a modified workpiece; the modified glue solution is prepared through the following steps: heating the epoxy resin to 135° C. Based on epoxy resin, trilauryl phosphite was added according to 0.4wt%, zirconium oxychloride was added according to 0.1wt%, and borax was added according to 0.5wt%; the vacuum heating and positive pressure heating were used to cycle alternately for four times, and the vacuum The first cycle of heating and posit...

Embodiment 3

[0051] The difference from Example 1 is that in step 1, the activation solution includes hydroxyalkylphenol polyoxyethylene ether and aminosilane coupling agent in a mass ratio of 2.5:0.7; the rest are the same as in Example 1.

Abstract

The invention relates to the field of fence production, and particularly discloses a production process of a composite fence for residence and the fence manufactured thereof.The production process of the composite fence for residence comprises the following steps that firstly, a workpiece is placed in an activating solution to be activated at the temperature of 40-55 DEG C, and the activated workpiece is obtained; the activating solution comprises polyoxyethylene ether and an amino silane coupling agent; secondly, the surface of the activated workpiece is coated with a modified glue solution, and a modified workpiece is obtained; thirdly, composite paint is sprayed to the surface of the modified workpiece, irradiation treatment is conducted, and a base material is obtained; the composite paint is prepared from fluororesin, hydroxy propyl distarch phosphate, styrene-acrylic emulsion and mica iron oxide; and 4, spraying synergistic particles on the surface of the base material, and carrying out spray burning treatment to obtain the composite fence. The fence prepared through the method is high in damp and heat resistance stability, and in a salt spray resistance test, the surface of the fence can be free of corrosives within 720 h, and corrosion resistance is good.

Description

technical field [0001] The present application relates to the field of fence processing, and more particularly, to a production process of a composite fence for residential use and the produced fence. Background technique [0002] Fences are a common protective facility in our lives. They are widely used in gardens, highways, railways, construction sites and other places. Metal fences are also used in houses such as villas. [0003] For example, the application document with publication number CN107583836A discloses a fence anti-corrosion process, including three steps of rust removal, painting and wrapping heat shrinkable film: (1) rust removal: use a laser rust removal device to remove rust on the fence; ( 2) Spray painting: Epoxy anti-corrosion series paint is used, and the spraying process is as follows: A. When applying the brushing method, paint in the same direction; B. When applying spraying, the speed of the spray gun should be uniform, and the nozzle should be kep...
