Abstract

The invention relates to phenolic resin anti-crack mortar and a preparation method of the phenolic resin anti-crack mortar, and belongs to the technical field of anti-crack mortar of thermal insulation phenolic aldehyde material used for outer walls. The technical problem to be solved is to provide anti-crack mortar and the preparation method of the anti-crack mortar, the anti-crack mortar is based on inorganic and organic binding agents, and water-retaining agents, hydrophobing agents, water repellents and anti-crack auxiliaries including xylogen, pentatricopeptide repeats (PPR) fiber and the like are added, so that a phenolic aldehyde plate is protected from outside damage, and an effective protection layer is formed. The technical scheme is that the anti-crack motar comprises, by weight, 115-140 parts of alumina cement, 60-80 parts of heavy calcium carbonate powders, 280-330 parts of quartz sands, 16-25 parts of 5044 rubber powders, 1-5 parts of water repellents, 1-5 parts of organic silicon resin hydrophobing agents, 1-5 parts of cellulose, 0.5-3 parts of xylogen and 0.3-2 parts of PPR fiber. The phenolic resin anti-crack mortar and the preparation method of the phenolic resin anti-crack mortar are widely applied to the technical field of phenolic aldehyde material anti-crack mortar.

Description

A kind of resol anticracking grout and preparation method thereof
Technical field
A kind of resol anticracking grout of the present invention and preparation method thereof belongs to the anticracking grout technical field of outer wall thermal insulation phenolic materials.
Background technology
Exterior-wall heat insulation is the important measures that realize building energy conservation, and is used for the EPS(styrofoam of exterior-wall heat insulation), the XPS(extruded sheet) there is disaster hidden-trouble in lagging material, so the phenolic foam heat insulation plate of superior performance receives increasing concern.But due to the phenolic aldehyde self character, there are many problems in the phenol exterior wall heat-preserving system, be acid as warming plate, and mortar is alkalescence, when exterior wall uses, because the reasons such as rainwater induce reaction, thereby causes sag of protecting coating, destroys the heat-insulation system function.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art; provide a kind of take inorganic, organic binder bond as main; add the cracking resistance auxiliary agents such as water-holding agent, hydrophobicity, hydrophober and xylogen, PPR fiber; the protection phenolic board is not subjected to extraneous the damage, forms anticracking grout of effective protective layer and preparation method thereof.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the raw material that a kind of resol anticracking grout adopts is according to following weight part proportioning:
High-alumina cement 115-140 part, dry powder 60-80 part, quartz sand 280-330 part, 5044 rubber powder 16-25 parts, hydrophober 1-5 part, silicone resin hydrophobizing agent 1-5 part, Mierocrystalline cellulose 1-5 part, xylogen 0.5-3 part, PPR fiber 0.3-2 part.
Described hydrophober is B1490 hydrophober.
Described silicone resin hydrophobizing agent is POWDER A.
Described quartz sand is that 40-70 order quartz sand and 20-40 order quartz sand mix according to weight part ratio 2:1.
Described high-alumina cement pH value is 7-8.
A kind of preparation method of resol anticracking grout: described high-alumina cement, dry powder, quartz sand, 5044 rubber powders, hydrophober, silicone resin hydrophobizing agent, Mierocrystalline cellulose, xylogen and PPR fiber mixing are got product.
The beneficial effect that the present invention compared with prior art has is: the cement that uses in the formula that the present invention adopts is the high-alumina cement of neutrality, and its pH value is 7-8, then coordinates other auxiliary agents to solve to react with acid phenolic-aldehyde heat-insulation board and water-fast problem; The present invention and adhesive mortar and interfacial agents form the phenolic aldehyde outer heat preservation system,, reach weather resistant experiment and prove that this cover system can satisfy the requirement of heat-insulation system greater than the anti-test of drawing of 0.1MPa through tensile strength.Technique of the present invention is simple simultaneously, is easy to produce, and is fit to extensively promote.
5044 rubber powders that relate in the technical program are a kind of redispersible vinyl acetate of chance water with anti-saponification performance/ethylene copolymer rubber powders.Due to its relatively high ethylene content, rubber powder has fabulous snappiness.Hydrophober B1490 is the dispersed layered silicate material of a kind of nano level.POWDER A is the silicone resin hydrophobizing agent available from German Wa Ke company.
