Description

A kind of stalk fibre toughening mortar and preparation method thereof
Technical field
The present invention relates to building material fields, and in particular to a kind of stalk fibre toughening mortar and preparation method thereof.
Background technology
Mortar be building on lay bricks use cohere substance, by a certain proportion of sand and cementing material (cement, lime Cream, clay etc.) it adds water into.Mortar is common have cement mortar, mixed mortar (or being cement-lime mortar), lime mortar and Clay mortar.
Existing mortar is usually the sand by silicate series cement, the materials such as additive and water, according to a certain percentage By certain stirring technique and a kind of manufactured construction material, for building by laying bricks or stones and plastering engineering.
However, existing mortar is since poor toughness is so as to cause tensile strength low, it is easy to crack the problems such as, limit mortar It uses, and existing tougher material is of high cost, and environment is polluted, it is unfavorable for sustainable development.
The content of the invention
The present invention is directed to the problem of above-mentioned mortar poor toughness, provides a kind of stalk fibre toughening mortar and its preparation side Method, stalk fibre toughening mortar of the invention reduce local stress collection by reducing crackle, the continuity of amplified medium material In, reinforced mortar connectivity and enhancing crack deflection toughness, so as to improve the toughness of mortar material.
The technical solution adopted by the present invention is as follows:
A kind of stalk fibre toughening mortar, in terms of parts by weight, including following components:20-40 parts of Portland cement, 50-70 parts of perlite, 15-35 parts of iron tailings, give up 15-30 parts of porcelain powder, 15-20 parts of slag powders, 8-20 parts of stalk fibre, starch ether 1-1.5 parts, 0.5-2 parts of hydroxypropyl cellulose, 3-8 parts of polyvinyl alcohol, 1-6 parts of styrene-acrylic emulsion, 2-4 parts of methyl cellulose ether.
The mortar of the present invention is using perlite as one of main ingredient, because perlite has, unit weight is light, thermal conductivity factor Low, fire resistance is good, and sound insulation value is good, and gap is subtle, and chemical property is stablized, and drying shrinkage is small, the characteristics such as nontoxic, so as to Increase the toughness of mortar;Stalk fibre is added simultaneously, stalk fibre belongs to light porous fibrous material, and elasticity modulus is relatively It is low, as toughening element, the dry contraction of mortar early stage is reduced, inhibits the generation and growth of microcrack, while light porous and appearance Weight is small, has good thermal and insulating performance, plays the effect that auxiliary improves heat-insulating property, and stalk fibre can absorb impact energy Amount, effectively reduces crackle, and amplified medium material continuity reduces shock wave and is blocked caused stress raisers, so as to carry The toughness of high mortar;And hydroxypropyl cellulose is high modulus fibre, and it is suitable with the elasticity modulus of mortar, significantly reduce guarantor's sand The drying shrinkage of starch middle and later periods, so as to improve the toughness of mortar;In addition, hydroxypropyl cellulose, stalk fibre, methyl are fine The plain ether of dimension, polyvinyl alcohol, styrene-acrylic emulsion is in the case of mutual cooperation so that the adhesive property of mortar is enhanced, so as to improve The cohesive force and flexibility of mortar material;Starch ether as water-keeping thickening material, can improve the toughness of mortar in mortar simultaneously And water-retaining property, starch ether makes the moisture in mortar be not easy to lose, and is progressively discharged within long period of time, and it is good to assign mortar Good water-retaining property and workability, starch ether also act as the effect that sagging falls after prevention mortar is smeared.In addition, by recycling iron tail Ore deposit and waste ceramic powder can not only be cost-effective as the raw material of mortar, but also can be damaged to avoid to environment, together When iron tailings in metal powder and waste ceramic powder in ceramic powders can be dispersed in sand as disperse Second Phase Particle Among slurry, crack propagation can be made to run into obstacle, crack deflection toughening occur, so as to increase the toughness of mortar material.
Preferably, in terms of parts by weight, including following components:25-35 parts of Portland cement, 55-65 parts of perlite, 20-30 parts of iron tailings, give up 20-25 parts of porcelain powder, 15-18 parts of slag powders, 10-15 parts of stalk fibre, 1.2-1.5 parts of starch ether, hydroxyl 1-1.5 parts of propyl cellulose, 4-7 parts of polyvinyl alcohol, 2-5 parts of styrene-acrylic emulsion, 3-4 parts of methyl cellulose ether.
Preferably, in terms of parts by weight, including following components:30 parts of Portland cement, 60 parts of perlite, iron tailings 25 parts of powder, give up 20 parts of porcelain powder, 15 parts of stalk fibre, 15 parts of slag powders, 1.2 parts of starch ether, 1.2 parts of hydroxypropyl cellulose, poly- second 5 parts of enol, 5 parts of styrene-acrylic emulsion, 3 parts of methyl cellulose ether.
Preferably, the stalk fibre be length≤5nm after shear treatment maize straw through over-richness be 8% It dries and obtains after soaking with sodium hydroxide 10h.Maize straw eliminates plant fibre through the soaking with sodium hydroxide 10h that over-richness is 8% Pectin in dimension, and leave interface between single fiber, can reinforcing fiber and material bond strength, improve the tensile strength of material, Reinforcing material toughness.
Preferably, a kind of preparation method of stalk fibre toughening mortar, comprises the following steps:It accurately weighs by weight proportion Various raw material, first by Portland cement, perlite, iron tailings powder, give up porcelain powder, and starch ether is uniformly mixed, is then stirring Stalk fibre, hydroxypropylcelluloether ether, polyvinyl alcohol, styrene-acrylic emulsion and methyl cellulose ether are added in stir together during mixing It mixes, then adds water stirring, it can construction usage after stirring evenly.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:
1. the present invention reduces the dry contraction of mortar early stage by adding fibre stalk, inhibit the generation and growth of microcrack, Crackle is effectively reduced, amplified medium material continuity reduces shock wave and is blocked caused stress raisers, so as to improve sand The toughness of slurry./V stalk and hydroxypropyl cellulose, methyl cellulose ether, polyvinyl alcohol, styrene-acrylic emulsion are cooperating simultaneously In the case of so that the adhesive property of mortar is enhanced, so as to improve the cohesive force of mortar material and flexibility.
2. the present invention is by the use of iron tailings and waste ceramic powder as one of raw material, can not only can be cost-effective, but also can It is damaged to avoid to environment, and the ceramic powders in the metal powder and waste ceramic powder in iron tailings can be used as disperse the Two-phase even particulate dispersion can make crack propagation run into obstacle among mortar, crack deflection toughening occur, so as to increase mortar The toughness of material.
