Glass fiber reinforcement polymer modification cement for curtain wall board and preparing method

Abstract

The invention provides glass fiber reinforcement polymer modification cement for a curtain wall board and a preparing method. The cement is prepared from glass fiber, water, quartz sand, polymer, coal ash, silica fume, cement, a water reducing agent, an anti-foaming agent and a silane coupling agent. The glass fiber, the quartz sand, the coal ash, the silica fume and the cement which are metered well are thrown into a mixing machine to be mixed for 3 min; the polymer and the anti-foaming agent are mixed uniformly and added into the mixing machine to be mixed for 2 min; the water reducing agent and the silane coupling agent are poured into water to be mixed uniformly, added into the mixing machine by three times and stirred for 2 min. The glass fiber and the polymer are added into mortar, the mechanical performance, the anti-aging performance and the anti-frost property of the cement are improved, the life of the curtain wall structure under the effect of freezing and thawing damage, high temperature and high humidity is prolonged, the service period is greatly shortened, and the later-stage maintenance cost is reduced greatly.

Description

technical field [0001] The invention relates to a glass fiber reinforced polymer modified cement, and also relates to a preparation method of the glass fiber reinforced polymer modified cement. A glass fiber reinforced polymer modified cement and a preparation method are proposed mainly for the requirement of curtain wall panels. Background technique [0002] At present, my country's curtain wall structure design requires that the curtain wall has the same service life as the building structure, which puts forward strict technical requirements for the curtain wall materials. In cold regions such as Northeast China, North China, and Northwest China, ordinary curtain wall materials are often damaged due to freeze-thaw cycles and alternating effects of high temperature and high humidity. With the passage of time, the internal structure is eroded, so that the mechanical properties of the curtain wall material cannot meet the requirements of use, affecting the normal service lif...
