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 Phenolic resin anti-crack mortar and preparation method thereof
Technical field
A kind of Phenolic resin anti-crack mortar 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 realizing building energy conservation, and for the EPS(styrofoam of exterior-wall heat insulation), 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 phenolic aldehyde self character, phenol exterior wall heat-preserving system exists many problems, if warming plate is acid, and mortar is alkalescence, when exterior wall uses, because the reasons such as rainwater induce reaction, thus causes sag of protecting coating, destroys heat-insulation system function.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art; there is provided a kind of based on inorganic, organic binder bond; add the cracking resistance auxiliary agent such as water-holding agent, hydrophobicity, hydrophober and xylogen, PPR fiber; protection phenolic board does not damage by extraneous, 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 for: the raw material that a kind of Phenolic resin anti-crack mortar adopts is according to following weight:
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 Phenolic resin anti-crack mortar: the mixing of described high-alumina cement, dry powder, quartz sand, 5044 rubber powders, hydrophober, silicone resin hydrophobizing agent, Mierocrystalline cellulose, xylogen and PPR fiber is got product.
The high-alumina cement that the cement used in the formula that the beneficial effect that the present invention compared with prior art has adopts for: the present invention is neutrality, its pH value is 7-8, then coordinates other auxiliary agents to solve to react and resistance to water problem with acid phenolic-aldehyde heat-insulation board; The present invention and adhesive mortar and interfacial agents form phenolic aldehyde outer heat preservation system, and what be greater than 0.1MPa through tensile strength draws anti-test, and weather resistant experiment proves that this cover system can meet the requirement of heat-insulation system.Present invention process is simple simultaneously, is easy to produce, and is applicable to extensively promoting.
5044 rubber powders related in the technical program are a kind of chance water redispersible vinyl acetate/ethylene copolymer rubber powders with resisting saponification.Due to the ethylene content that it is relatively high, rubber powder has fabulous snappiness.Hydrophober B1490 is a kind of nano-scale dispersion layered silicate material.POWDER A is the silicone resin hydrophobizing agent purchased from German Wa Ke company.
