Description
Technical Field

Background
At present, various fences are widely applied to the fields of engineering construction, municipal administration, traffic safety and the like. The fence is mainly a beam-column combined steel or iron fence, and the fence can have the problems that serious corrosion and the like occur when the service life of the fence is not up to the expected service life in the actual use process, so that the service life of the general steel or iron fence is only 3-5 years. In addition, the maintenance and reinforcement cost of the fence is increased due to the corrosion of the fence and the like. Therefore, the novel composite fence which is light in weight, high in strength and corrosion-resistant has important practical significance.
In recent years, fiber reinforced composite materials have been widely studied, providing a basis for the application of fiber reinforced composite fences. Research shows that the thermoplastic glass fiber reinforced fence is superior to the traditional steel fence in energy absorption in the bending damage process; the strength, rigidity and impact characteristics of the glass fiber reinforced fence can meet the requirements. The strength of basalt fiber is superior to that of glass fiber and aramid fiber, and the basalt fiber has good heat insulation and high temperature resistance performance and lower price than that of carbon fiber. In addition, the basalt fiber has better chemical stability and has the characteristics of acid resistance, alkali resistance and corrosion resistance. Meanwhile, compared with other common fibers, the basalt fiber is the only green and environment-friendly fiber which can be recycled. Therefore, the basalt fiber composite reinforced material is used for producing and manufacturing various fences, and the novel basalt fiber composite reinforced fence with better performance than glass fiber, high strength, corrosion resistance, elastic deformation resistance and strong fatigue resistance can be obtained. In addition, the basalt fiber composite material has the density of 1/4 of that of steel, so that the basalt fiber composite material has light weight and increases the convenience in transportation and installation processes. And secondly, the problem that the steel fence is easy to rust is solved, and the comprehensive performance of the steel fence is far from that of similar products made of materials such as super-hard plastic, glass fiber reinforced plastic, steel and the like, and the steel fence has wide application prospect. Therefore, the invention provides a novel basalt fiber composite reinforced fence.

s1, taking a die matched with a fence, and respectively fixing the die at corresponding equipment;
s2, pulling a selected amount of modified basalt fibers into the die in the S1 according to the material requirement of the fence;
s3, mixing the synthetic resin, the antioxidant, the coupling agent and the stabilizer to obtain a mixture, and carrying out melt processing on the mixture to obtain a plastic melt;
s4, carrying out infiltration treatment on the modified basalt fiber in infiltration equipment by using the plastic melt prepared in the step S3;
s5, after the temperature of the die reaches the set temperature, the reinforcing material of the synthetic resin enters the die and is solidified;
s6, starting a photosensitive automatic cutting machine, and respectively cutting according to the set length to obtain the fence.
In the step S3 of this example, the mixture was melted at a temperature of 250℃and a pressure of 20MPa, and the mixture was stirred at a rotation speed of 500r/min to obtain a plastic melt, and in the step S4, the long basalt fiber was infiltrated with the plastic melt at a temperature of 270℃and a pressure of 30MPa for a treatment time of 13S.

Comparative example 1.
The basalt was not modified unlike example 3.
Comparative example 2.
The difference from example 3 is that the addition amount of sepiolite powder in the preparation method of the modified basalt fiber is 5% by mass of basalt.
Comparative example 3.
The difference from example 3 is that no coupling agent is added.
The performance of the fences produced in examples 1 to 3 and comparative examples 1 to 3 was tested, and the test results are shown in the following table.
As can be seen from examples 1-3; the impact strength and bending strength of the novel basalt fiber composite reinforced fence manufactured by the method are greatly improved, and the comprehensive performance of the novel basalt fiber composite reinforced fence is far from that of similar products made of materials such as super-hard plastics, glass fiber reinforced plastics, steel and the like.
From comparative example 1 and example 3, it can be seen that after a certain amount of sepiolite powder is added in the basalt modification process and melted at high temperature, basalt can be melted with sepiolite and chemically reacted to form a modified basalt with a new network structure, so that the mechanical properties of basalt fibers can be obviously improved, and meanwhile, no coupling agent is added, so that the combination effect of polypropylene and the modified basalt fibers is poor, and the mechanical properties of fences are affected.
