Abstract
The invention discloses an anti-crack polymer mortar which comprises the components in parts by weight as follows: 300-400 parts of ordinary Portland cement, 50-150 parts of ash calcium powder, 550-650 parts of silica sand, 15-20 parts of redispersible emulsion powder, 4-6 parts of polypropylene fiber, 2-5 parts of hydroxypropyl methyl cellulose, 1-2 parts of a naphthalene-based superplasticizer, 0.5-0.8 part of a water repellent agent and 100-120 parts of an expanding agent, wherein the particle size of the silica sand ranges from 60 meshes to 90 meshes. The prepared anti-crack mortar requires little water during use, and has a good anti-crack property.
Description
Technical field
The present invention relates to a kind of polymers anti-cracking mortar.
Background technology
On the basis of traditional mortar, by allocating different function admixtures into, can give mortar with special function, make the building function mortar of various uses, more traditional mortar has obvious advantage.Anticracking grout be anti-fissuring agent, cement and the sand be made up of polymer emulsion and admixture make by a certain percentage can meet certain distortion and keep indehiscent mortar, be mainly used in the front cover of the outer layer surface such as external wall outer insulation or inside holding aspect, styrofoam, extruded sheet.Existing anticracking grout water requirement is large, and resistance to cleavage is unsatisfactory.
Summary of the invention
The object of the invention is to solve the defect existed in prior art, providing that a kind of water requirement is less, the good anticracking grout of resistance to cleavage.
In order to achieve the above object, the invention provides a kind of polymers anti-cracking mortar, comprise the component of following weight part: ordinary Portland cement 300-400 part, sierozem power 50-150 part, quartz sand 550-650 part, redispersable latex powder 15-20 part, polypropylene fibre 4-6 part, hydroxypropyl methyl cellulose ether 2-5 part, naphthalene series high-efficiency water-reducing agent 1-2 part, hydrophober 0.5-0.8 part, swelling agent 100-120 part; Wherein quartz sand size size is 60-90 order.
Above-mentioned polymers anti-cracking mortar also comprises triterpenoid saponin; Triterpenoid saponin consumption is the 2.5%-4% of ordinary Portland cement weight.
The preferred FDN high efficiency water reducing agent of naphthalene series high-efficiency water-reducing agent; Swelling agent preferential oxidation calcium class swelling agent.
Inventive polymers anticracking grout optimum ratio is: ordinary Portland cement 350 parts, sierozem power 100 parts, quartz sand 600 parts, acrylic copolymer 15 parts, polypropylene fibre 5 parts, hydroxypropyl methyl cellulose ether 3 parts, FDN high efficiency water reducing agent 1 part, hydrophober 0.6 part, calcium oxide expansion agents 110 parts, triterpenoid saponin 11 parts.
The present invention has the following advantages compared to existing technology: the present invention utilizes hydroxypropyl methyl cellulose ether as polymer water-holding agent, effectively can reduce the rate of drying of mortar, to reduce plastic shrinkage; Utilize swelling agent complementary contraction; Utilize the toughness of polypropylene fibre reinforced mortar; Utilize naphthalene series high-efficiency water-reducing agent can reduce the water requirement of mortar, effectively can improve the intensity of mortar with the use of air entrapment agent, improve the frost heave stress of mortar; Utilize hydrophober effectively can improve water resistance; Control to gather materials and the ratio of filler simultaneously, effectively improve the resistance to cleavage of mortar.Anticracking grout prepared by the present invention only need add the water of 15-18% when using, water requirement is few.And the performance of this anticracking grout is: backfin is than 1.92-1.94, normal temperature tensile bond strength 0.95-0.96MPa, operable time 2h.
