Problems solved by technology

[0005] The existing waterproof and anti-crack mortar has good water resistance and crack resistance because the modifier contains redispersible latex powder, and polypropylene fibers are used to increase the crack resistance of the mortar. Because there will be many vehicles passing by on bridges or roads, vehicles will emit a lot of polluting exhaust gas during driving, and these polluting gases will float into the air, which will affect the environment

Abstract

The invention discloses waterproof, anti-cracking and environment-friendly polymer mortar for outdoor use, and a preparation method of the waterproof, anti-cracking and environment-friendly polymer mortar. The waterproof, anti-cracking and environment-friendly polymer mortar for outdoor use is prepared from the following components in parts by weight: fly ash, slag powder, graded sand, cement, redispersible latex powder, cellulose ether, gypsum, polypropylene staple fibers, polyvinyl alcohol (PVA) fibers, nano silica and an additive, wherein the additive is prepared from a water reducing agentand an absorbing agent according to a mass ratio of (2-3) to (1-2); the absorbing agent is prepared from the following components in parts by weight: negative ion powder, bamboo fibers, activated carbon, cerium oxide, a sphagnum moss extract, nano titanium dioxide, organosilicone modified polyurethane and ethyl acetate; the preparation method comprises the steps of (1) preparing a first mixture;(2) preparing a finished product. The waterproof, anti-cracking and environment-friendly polymer mortar for outdoor use has the advantages of being good in waterproof property and anti-cracking ability, being capable of purifying the air, and being more environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of mortar, more specifically, it relates to an outdoor polymer waterproof crack-resistant environmental protection mortar and a preparation method thereof. Background technique [0002] With the rapid development of China's infrastructure construction, higher requirements are put forward for the service life of infrastructure projects, especially for bridges, high-speed railways, special railway lines, expressways, and civil buildings, which have higher requirements for design, construction, and performance. However, due to incomplete design, inadequate construction, imperfect operation and maintenance, and natural force majeure factors, such as leakage, ice disaster, corrosion, etc., many existing concrete structures have suffered serious structural damage, such as cracks in structures and peeling of concrete on the surface , exposed steel bars and other diseases, and damage to road surfaces, bridge piers, ...
