Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of polymer mortar, to solve the problem that when the existing polymer mortar proposed in the above background technology is used in the outdoor environment for a long time, the anti-aging performance of the polymer itself is relatively poor, so that it is exposed to the external environment. Aging caused by ultraviolet and infrared radiation will lead to a decrease in the durability of cement mortar and affect the safety of mortar buildings.

Abstract

The invention discloses high-molecular mortar, relates to the technical field of high-molecular mortar, and aims to solve the problems that when the existing high-molecular mortar is used in an outdoor environment for a long time, the high-molecular polymer of the existing high-molecular mortar is poor in ageing resistance, so that the existing high-molecular mortar is aged under the irradiation of external ultraviolet rays and infrared rays, and the durability of cement mortar is reduced. And the safety of the mortar building is influenced. Comprising the following components in percentage by weight: 30-35% of cement; 40%-45% of quartz sand; 5%-7% of a thickening agent; 1%-3% of polyoxyethylene; 5%-8% of an anti-aging auxiliary agent; 0.5%-1% of polypropylene fiber; 5%-10% of surface modified nano zinc oxide; a binder; the surface-modified nano-zinc oxide is prepared from surface-modified nano-zinc oxide and an anti-aging aid, the surface-modified nano-zinc oxide is prepared from surface modified nano-zinc oxide, the anti-aging aid is prepared from an ultraviolet light absorber, a light stabilizer and an antioxidant in a combined and matched manner, and the adhesive is internally prepared from nigrosine cured particles and a binding agent component, the surface-modified nano-zinc oxide is subjected to surface modification by virtue of a coupling agent gamma-aminopropyltriethoxysilane.

Description

technical field [0001] The invention relates to the technical field of polymer mortar, in particular to a polymer mortar. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) Or called cement lime mortar), lime mortar and clay mortar, polymer mortar is a new type of building material that has emerged in engineering in recent years. It is made of cementitious materials and organic polymers that can be dispersed in water. Widely used, polymer mortar is a mixture of cement, aggregate and organic polymers that can be dispersed in water. A polymer can be a homopolymer polymerized from one monomer, or a copolymer polymerized from two or more monomers. The polymer must form a film covering the cement particles under ambient conditions and form a strong bond between the cement body and the aggregate. [0003] However, when the existing polymer mo...
