Problems solved by technology

[0003] The steel wire rope is easy to oxidize, resulting in the decline of the mechanical properties of the entire net, weakening or losing the protective effect on the slope
Many steel wire ropes have undergone surface galvanizing and other methods for anti-rust treatment. However, there are varying degrees of acid rain or alkaline geological environment in many parts of the country. In an acid-base environment, the anti-rust treated steel wire rope is still easy rust
In addition, during the paving process, the friction with the rock will also destroy the anti-rust layer on the surface. Once damaged, the steel wire mesh will rust quickly

Abstract

The invention discloses an ultra-high molecular weight polyethylene fiber slope protective net and a preparation method thereof. The ultra-high molecular weight polyethylene fiber slope protective net comprises the following components in parts by weight: 60-90 parts of ultra-high molecular weight polyethylene fibers and 10-40 parts of flame-retardant adhesive, wherein the flame-retardant adhesive is a dry product of flame-retardant liquid cement, and the flame-retardant liquid cement is composed of 20-30 parts of polymer, 40-50 parts of water, 5-20 parts of inorganic fillers and 0.001-0.005 part of antioxidant. Since the ultra-high molecular weight polyethylene fibers are used as the base material of the protective net disclosed by the invention and the tailor-made flame-retardant liquid cement is combined with the ultra-high molecular weight polyethylene fibers, the obtained slope protective net is acid and alkali resistant, free of rust for ever, good in weather resistance, long in service life, excellent in mechanical properties, good in protection effect, small in mass and easy to pave or install. Furthermore, the preparation method is simple, the material source is wide and the cost is low, so that the ultra-high molecular weight polyethylene fiber slope protective net is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of polymer science, in particular to an ultra-high molecular weight polyethylene fiber slope protection net and a preparation method thereof. Background technique [0002] With the development of society, people pay more and more attention to safety. Slope treatment is a disaster prevention and control project with complex protective net technology and difficult construction. With the rapid development of highway and railway construction and the increasing number of large-scale key engineering projects, people pay more and more attention to safety issues, and the problem of slope management is becoming more and more prominent. The slope protection net system is divided into: active protection system and passive protection system. At present, no matter the active protection system, the flexible net made of steel wire rope is mainly used to cover and wrap the required protection slope or rock, so as to limit the weath...
