A kind of base material of mortar for adhering heat insulating plate
Technical field
The present invention relates to base material of mortar for adhering, relate in particular to a kind of base material of mortar for adhering heat insulating plate.
Background technology
Appear at Europe the seventies 20th century of exterior wall heat-preserving system, by the thermal exchange that low material of heat transfer coefficient such as polystyrene board etc. stop indoor and outdoor is set on exterior wall, keep the temperature of indoor suitable people's life with the work of refrigerating and heating systems in the ancillary chamber, thereby reach purpose of energy saving.Warming plate such as polystyrene board etc. use mortar bonding usually on exterior wall, perhaps adopt mortar bonding to fix with anchoring piece again.Yet there are the not enough problem of cohesive strength in ordinary mortar and warming plate, and the coefficient of shrinkage is bigger, and in the ambient moisture change procedure, intensity is affected, and warming plate comes off easily after the moisture absorption.
Granted publication number discloses the outer compound binding agent of organic-inorganic of a kind of polystyrene thermal insulation plate exterior wall for the Chinese invention patent of CN1249187C; it is made up of silicon sol, styrene-propene acid polymer emulsion, sequestrant chromium nitrate and filler asbestos and lime carbonate etc.; binding agent cohesive strength, water resistance etc. have been improved; but this product easily produces be full of cracks, hollowing, comes off; and used asbestos and heavy metallic salt chromium nitrate to environment and human body harmful, be unfavorable for environment protection.
Publication number is that the Chinese invention patent application of CN1821153A discloses a kind of dry powder mortar system of building external insulation polystyrene insulation board, comprise adhesive mortar and anticracking grout, wherein the powder of adhesive mortar comprises ordinary Portland cement 20-35%, 40~80 order quartz sands or river sand 35~45%, redispersible polymer rubber powder 2~5%, water-holding agent 0.02~0.1% and compound additive 0.1~1%, the powder of anticracking grout comprises ordinary Portland cement 15-30%, 80~120 order quartz sands or river sand 35~45%, redispersible polymer rubber powder 2~5%, water-holding agent 0.02~0.1%, compound additive 0.1~1% and fiber 1.5~3.5%, owing to need respectively adhesive mortar layer and anticracking grout layer to be constructed, construction period is long, the expense height, and two-layer coefficient of expansion difference, in cold and hot conversion process, occur the crack easily, influence its cohesive strength.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of cohesive strength height is provided, cohesive strength is subjected to the little base material of mortar for adhering heat insulating plate of humidity effect.
The technical scheme that realizes above purpose is:
A kind of base material of mortar for adhering heat insulating plate, comprise A, B two components, it is characterized in that: the quality group of A component becomes 0.5~2 part of 100 parts of suitable positions, 100~180 parts of quartz sands, 2~3 parts of high efficiency water reducing agents, 0.5~2 part of lignocellulose and ether of cellulose; The B component is self-cross linking type binding agent 15~30 mass parts.
In a kind of optimized technical scheme, described suitable positions is an ordinary Portland cement.
In a kind of optimized technical scheme, described quartz sand is 60-200 purpose grating quartz sand.
In a kind of optimized technical scheme, described high efficiency water reducing agent is trimeric cyanamide or polycarboxylic acid high efficiency water reducing agent.
In a kind of optimized technical scheme, described lignocellulose is that average fiber length is the lignocellulose of 250~500 μ m.
In a kind of optimized technical scheme, described ether of cellulose is methyl hydroxyethylcellulose ether or methylhydroxypropylcellulose ether.
In a kind of optimized technical scheme, described self-cross linking type binding agent is an acrylate copolymer.
Base material of mortar for adhering heat insulating plate of the present invention only need mix the back with about about 20% the water of its total mass and just can use, and construction process is simple; Mortar and adhering heat insulating plate intensity height, difficult drop-off after the moisture absorption need not to reinforce with anchoring piece, has reduced working procedure.
Embodiment
Embodiment 1
