Abstract
The invention relates to a modified reclaimed rubber aggregate surface mortar, and specifically relates to a method for applying modified reclaimed rubber aggregate in external-wall thermal-insulation surface mortar. Each ton of the mortar comprises the components of, by weight: 310-400kg of cement, 600-690kg of washed fine sand, 10-15kg of re-dispersible latex powder, 1.5-2.5kg of hydroxypropyl methyl cellulose ether, 1kg of polypropylene fiber, and 35-50 parts of a rubber aggregate. The preparation method is as follows: a silane coupling agent with a mass accounting for 2% of that of the rubber aggregate is weighed and added into 95% ethanol, such that a solution is prepared; rubber particles are sufficiently wetted by using the solution, and are dried in air and preserved for later use; the components are weighed according to the weights; and stirring, settling, and high-speed stirring are carried out, such that the surface mortar is obtained. The surface mortar provided by the invention has important significance in waste utilization and environment protection. According to the invention, mortar cost is reduced, and mortar freeze-thaw strength and toughness are improved.
Description
Technical field
The present invention relates to a kind of plastering mortar of modification regeneration rubber aggregate, specifically belong to a kind of mortar that modification regeneration rubber is used for exterior-wall heat insulation, belong to construction work heat preservation mortar for outer wall preparation field.
Background technology
The prescription of the construction work heat preservation mortar for outer wall that generally uses now, the weight of each composition of mortar per ton: ordinary Portland cement: 350-400Kg; Fine sand: 580 ~ 610 Kg; Redispersable latex powder: 12 ~ 13 Kg; Hydroxypropyl methyl cellulose ether: 1.8 ~ 2.2 Kg; Polypropylene fibre: 1.3 ~ 1.5Kg; Starch ethers: 0.5 ~ 1Kg.There is the three aspects: shortcoming in this external thermal insulation finishing mortar: 1. between building band boiled water room outer wall place as there not being vertical moisture-proof barrier, can make external thermal insulation because freeze-thaw cycle produces local hollowing, come off.2. to contain ferrous components high for the common quartz sand in the aggregate, oxidation easily occurs cause the outer heat preservation system be full of cracks, come off.3. cement consumption is larger, and backfin is than large, and surface layer is easy to crack.
Summary of the invention
The object of the present invention is to provide that a kind of freeze thawing intensity is high, toughness is strong, the modification regeneration rubber aggregate plastering mortar of low cost of manufacture.
Technical solution:
The weight of the present invention's each composition of mortar per ton is: ordinary Portland cement: 310 ~ 380Kg; Washing fine sand: 600 ~ 690Kg; Redispersable latex powder: 10 ~ 15Kg; Hydroxypropyl methyl cellulose ether: 1.5 ~ 2.5Kg; Polypropylene fibre: 1 ~ 1.2 Kg; The rubber aggregate of modification: 35 ~ 50Kg.
Rubber aggregate method of modifying of the present invention is: the silane coupling agent that takes by weighing rubber aggregate quality 2%, be added in the alcohol of mass concentration 95%, make the coupling agent spirituous solution, rubber aggregate is fully wetting with the coupling agent spirituous solution, after stirring, leave standstill, until for subsequent use behind the particle surface complete drying of rubber aggregate.
Further: the method for modifying of rubber aggregate is: be 1% polyvinyl alcohol solution with mass concentration, rubber aggregate was fully soaked 1-2 hour, rubber aggregate takes out after will soaking, until for subsequent use behind the particle surface complete drying of rubber aggregate.
Described rubber aggregate is pulverized by junked tire and is formed, and the grain diameter of rubber aggregate is the 40-60 order, and the rubber kind of tire is natural rubber or cis-1,4-polybutadiene rubber or styrene-butadiene rubber(SBR).
Described redispersable latex powder is the multipolymer of vinyl acetate and ethene.
The staple length of described polypropylene fibre is 6mm ~ 10mm.
Described ordinary Portland cement label is P.O42.5 or P.O52.5.
Add modified rubber in the plastering mortar of the present invention and gather materials, can obviously improve freeze thawing intensity and the toughness of mortar.Therefore major cause has three aspects:: 1. the modification regeneration rubber aggregate is macromolecular material, and its formation mostly is mechanical disintegration, causes surface irregularity uneven, and this just is conducive to carry air, thus rubber aggregate mix the effect that just is equivalent to the solid air entrapment agent.2. the elasticity of rubber aggregate itself also can be alleviated the string stress that freeze thawing produces, but the freezing and thawing performance of Effective Raise mortar.3. the mortar that is mixed with rubber aggregate has the effect that absorbs strain energy, and the distortion that can improve mortar improves its toughness.
The advantage of comparing with existing prescription: rubber aggregate can improve the freeze thawing intensity of mortar; Improve mortar toughness; Use in addition waste old to gather materials, to economizing on resources, the significance of protection of the environment is arranged, reduce the consumption of part admixture, reduced the mortar cost.
