Problems solved by technology

[0003] Fiberglass sleeves are mainly used for repairing and strengthening protection of structural foundation pile foundations and pier columns (including concrete piles, steel piles and wooden piles) with various diseases such as corrosion, erosion, concrete shedding, and exposed steel bars, as well as for The pre-protection of new piers, however, the current existing glass fiber sleeves in the process of use, such as corrosion resistance, weather resistance and strength, cannot meet the high standard requirements for the use of glass fiber sleeves underwater. For this reason, we propose A kind of anti-corrosion fiberglass sleeve and its preparation method are proposed to solve the above problems

Abstract

The invention discloses an anti-corrosion glass fiber bush and a preparation method thereof, and relates to the technical field of glass fiber bushes. The anti-corrosion glass fiber bush comprises thefollowing components in parts by weight: 30-50 parts of polyhexamethylene terephthalamide resin, 40-50 parts of quartz sand, 20-40 parts of fly ash, 25-35 parts of barium sulfate powder, 10-20 partsof antioxidant, 8-10 parts of flexibilizer, 15-20 parts of weather-proof agent, 10-30 parts of glass fiber, 10-15 parts of glycerol tri(1,2- epoxy) propyl ether, 8-10 parts of defoaming agent and 30-40 parts of glass fiber bush. According to the glass fiber bush beneficial to corrosion prevention and the preparation method of the glass fiber bush, glass fibers with a certain particle size are added into a prepared grouting material, so that the prepared grouting material has excellent impact resistance; and by adding a polyhexamethylene terephthalamide resin, quartz sand, fly ash and barium sulfate powder, the prepared grouting material has good processability and mechanical strength, strong hydrolysis resistance and excellent comprehensive performance, so that when the grouting material is used on a glass fiber bush, the corrosion resistance and the stability of the grouting material are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of glass fiber sleeves, in particular to a corrosion-resistant glass fiber sleeve, and also relates to a preparation method of a corrosion-resistant glass fiber sleeve. Background technique [0002] With the development of society and economy, the number of bridges built is gradually increasing. The bridge piers are seriously damaged due to the loss of concrete caused by water erosion, the erosion of concrete by water microorganisms, and the lack of concrete caused by other reasons. There will be safety hazards, so in order to solve this phenomenon, it is necessary to protect the bridge piers. Due to its durability, corrosion resistance and underwater construction, the underwater glass fiber sleeve is suitable for repairing due to erosion, concrete falling off, and steel bar leakage. Reinforced concrete piles damaged in water such as diseases have a good effect and, therefore, are widely used. [0003] Fibe...
