Engineering patching material.In the prior art, the hardenite of ordinary mortar or the mortar of some other polymer modification is being chronically at
Under the natural conditions of the difference cycle period such as cold and hot, dry and wet, freeze thawing, easily cause mortar material and combined between adhesive material
Weakening strength；Due to the weakening of mortar self structure and intensity, the quality problems such as easily cracking, drum.And actually make
In, screed cracking not only influences the presentation quality of structure, but also hazardous medium may be penetrated into by the crack of surface layer mortar
To internal structure, cause steel bar corrosion, deteriorate project durability.
Compared to ordinary mortar, existing polymer mortar has larger carry in intensity, toughness, cementability and durability etc.
It is high.Such as Lin Yumei exists《The experimental study of Durability of Polymer-Modified Mortar》In one text, polymer is shown using orthogonal test
Dry powder and mortar is compared with ordinary mortar, and Polymer-Modified Mortar shows good mechanical property, adhesive property and durable
Performance.It is firm due to polymeric chain but polymer emulsion mortar still has existing in terms of durability and cost
Property and crosslinking degree, unsaturated bond existing for its inside influence endurance quality and further improve；Furthermore the cost of polymer is
Even more than 100 times of 10 times of cement, cost is higher.In addition, and not all polymer emulsion to the cementability of cement mortar
There can be improvement, it is probably because some polymer and cement system not phase that acrylic acid ester emulsion is added such as in mortar
Hold, influence hydrated cementitious process；And some polymer in itself as the alkalescence of cement system and degrade, such as chlorine partial emulsion
It can degrade in mortar.Therefore, select suitable polymer emulsion and be prepared into the polymer mortar of excellent performance, especially
It is that exploitation is a kind of and the emulsion modified mortar of the matching used bi-component polymeric of carbon fiber mesh is emphasis of the invention.
The content of the invention
The purpose of the present invention is for mechanical property, endurance quality existing for polymer latex-modified mortar in the prior art
Deficiency, there is provided a kind of carbon fiber mesh reinforces dedicated mortar and preparation method, and this production process is simple, production cost is low, gained
Mortar durability and excellent in mechanical performance.
To reach above-mentioned purpose, the technical solution adopted by the present invention is：
A kind of carbon fiber mesh reinforces dedicated mortar, and the mortar includes mortar powder and polymer emulsion；The polymerization

Fiber is chopped polypropylene fibre by 2 for 3-9mm:1 ratio composition.
A kind of carbon fiber mesh reinforces the preparation method of dedicated mortar, includes the following steps：
S1：It is polymer emulsion modified：Using semicontinuous nucleocapsid seeded emulsion polymerization method, in mass ratio 12:6:1:1 will be poly-
Butadiene emulsions, styrene, 2- acrylamide-2-methyl propane sulfonics and methacrylic acid are added in reaction kettle and mixed, and temperature is set
65-70 DEG C is set to, mixing time 5h；
S2：It is prepared by polymer emulsion mortar：40-50% cement, 40-60% graded sands, 2-4% SILICA FUMEs, 0.04-
0.08% water-reducing agent, 0.01-0.02% defoamers, 0.03-0.05% cellulose ethers and 0.1%-0.3% polypropylene fibres are uniform
Mixture is mixed to obtain, is then added mixture into cement, persistently stirs 10-20min, up to mortar powder；By polymer
Lotion is added in mortar powder, and the mass ratio that polymer emulsion accounts for mortar is 18-20%, persistently stirs 10-20min, to obtain the final product
To polymer emulsion mortar.
Preferably, polybutadiene lotion described in step S1 be, styrene, 2- acrylamide-2-methyl propane sulfonics and first
