Preparation technology of high-strength fireproof dustproof safety rope net

Abstract

The invention discloses a preparation technology of a high-strength fireproof dustproof safety rope net which comprises the steps: firstly, performing gamma ray irradiation treatment on polyethylene fiber; then improving an inorganic filler preparation method and adding a rhizoma coptidis extracting solution and zinc hydroxystannate in an inorganic filler preparing process, wherein a synergistic effect of the rhizoma coptidis extracting solution and the zinc hydroxystannate can obviously improve fire resistance and strength of a rope net product; then injection molding, drawing and stretchingto prepare net lines; finally, twisting the net lines through a twisting machine and putting the net lines on a net weaving machine to be woven into a safety rope net after performing hot steaming treatment. Compared with an existing product, the product disclosed by the invention has the characteristics of high strength, light net weight, thermal insulation, ventilation, light transmission, fireresistance, dust prevention, noise reduction and the like; meanwhile, the product further has stronger wear resistance, corrosion resistance and acid-base resistance; in addition, the safety rope netdisclosed by the invention has an obvious dustproof effect and can remarkably reduce the dust content in construction regions.

Description

technical field [0001] The invention relates to a preparation process of a high-strength fireproof and dustproof safety rope net, in particular to a preparation technique of a safety rope net which improves the strength and fireproof and dustproof ability of the safety rope net, and belongs to the technical field of rope net processing. Background technique [0002] With the development of society, people pay more and more attention to safety. With the rapid development of high-rise buildings, highways, railway construction, and the increasing number of large-scale key engineering projects, people pay more and more attention to safety issues. The demands placed on the quantity and quality of protective nets are increasing day by day. The safety net is the necessary protective equipment for the construction site to protect the construction workers, and its quality directly affects the life safety of the construction workers. At present, most of the rope nets in our country a...

Problems solved by technology

At present, most of the rope nets in our country are barbed wire or ordinary fiber protective nets. Ordinary fiber nets have low strength, are not wear-resistant, and are easy to puncture so that the safety of the protective net cannot be guaranteed. In the prior art, the ultra-high molecular weight polyethylene fiber The strands are twisted into strands, and the strands are woven and formed by a netting machine, which has high strength and stability in use. At present, some methods for improving the strength and corrosion resistance of the rope net have been reported. For example, patent 201711351436.5 discloses a method using The preparation method of the filler for improving the strength of the rope net wire includes the following steps: (1) preparation of base liquid, (2) preparation of graded filler, (3) preparation of finished filler; the prepared filler can be effectively used in the production of rope net wire The enhancement of its corrosion resistance, wear resistance, high strength and other characteristics has significantly improved the service life of the rope net line; patent 201711360995.2 discloses a preparation method of acid and alkali resistant polyethylene fiber rope net, including the preparation of irradiated polyethylene intermediate material, long-term Silk preparation and protective net preparation, through the use of 60Co source gamma rays to irradiate ultra-high molecular weight polyethylene, the mechanical properties of the fiber have a higher level, and the adsorption capacity of magnesium fluoride and palladium chloride can be improved at the same time. The net production rate is high, the cohesion between the filaments is strong, and the appropriate preparation conditions can reduce fiber damage. The obtained rope net has high breaking strength and impact resistance, and also has strong wear resistance and corrosion resistance. And acid and alkali resistance; patent 201711336787.9 discloses a production process of a corrosion-resistant and anti-aging rope net line, including the following steps: (1) polyethylene particle treatment, (2) inorganic filler preparation, (3) raw material weighing and mixing , (4) Finished product preparation, the invention has made a special improvement to the processing and preparation method of the rope net wire, which effectively improves the strength, corrosion resistance and wear resistance of the rope net wire, and prolongs its service life very well

[0003] Comparing the existing technologies, it can be found that although methods to improve the strength and corrosion resistance of safety rope nets have been reported, the strength of safety rope nets needs to be further improved for high-rise buildings. The fire-proof and dust-proof capability needs to be further improved, and there is no enlightenment solution to the above-mentioned technical problems in the prior art
