Description
Technical field
The present invention relates to building material technical fields, and in particular to a kind of exterior wall diatomite painting of the existing cob wall of repairing and reinforcement
Material.
Background technique
Zhejiang area is implemented in samll cities and towns' transformation process, finds still to preserve in the building structure to be rebuilt of many rural areas
A large amount of loam wall building, these loam walls building are a kind of record and rural tourism landscape to China's historical development
A characteristic.
However, due to it is long-term have a humid climate, the erosion of wind and factors, the loam wall such as of the remote past occur in various degree
Breakoff phenomenon, be mainly shown as: more apparent crack, metope corrode peel off etc..For the transformation of loam wall, it is necessary to first
First solve the problems, such as the metope of loam wall.That is, needing in view of the above-mentioned problems, to consider how guaranteeing rammed earth as far as possible
In the case where the original style and features of wall, waterproofness, LP blades and the durability of former metope are improved.
And current building coating finds to have easy cracking, fall off after carrying out coating transformation for loam wall, it is durable
Not high, the bad problem of correctional effect of property, it is clear that existing outer wall building coating is not able to satisfy completely for current rammed earth
The needs of wall transformation.Reach better correctional effect in order to which current loam wall is transformed, it is necessary to which special exterior wall applies
Material is guaranteed.
Summary of the invention
The purpose of the present invention is to solve at present cannot for existing building coating present in loam wall transformation process
The problem of meeting actual demand, provides a kind of exterior wall diatomite paint of existing cob wall of repairing and reinforcement.Specifically, the present invention is directed to
A large amount of loam walls that existing rural area is retained provide a kind of coating, the damaging problem caused by of the remote past to ensure
On the basis of improved loam wall can keep to a certain extent original inherent structure, improves the waterproofness of metope, prevents invading
Corrosion and durability.
In order to achieve the above object of the invention, the invention adopts the following technical scheme:
A kind of exterior wall diatomite paint of the existing cob wall of repairing and reinforcement, according to parts by weight, comprising:
2-3 parts of rubber powders,
0.1-0.5 parts of antimildew and antibacterial agents,
2-5 parts of epoxy resin,
1.5-2.5 part rice straw,
15-28 parts of diatomite,
55-75 parts of water-based exterior wall paints.
Diatomite is less for exterior coating at present, and when being used for exterior coating, and durability is not very well, originally
Application is to be able to ensure that the material can form preferable knot with existing loam wall with compounding for rubber powder using diatomite
Close effect；The application is mainly that the silicon characteristic of diatomite is utilized, it is made to be easy the progress that combines together with existing loam wall
Bonding.
Epoxy resin refers to the general name of the quasi polymer containing more than two epoxy groups in molecule.It is epoxy chloropropionate
The polycondensation product of alkane and bisphenol-A or polyalcohol.Due to the chemical activity of epoxy group, can be made with a variety of compounds containing active hydrogen
Its open loop, solidification crosslinking generates reticular structure, therefore it is a kind of thermosetting resin.Here, taking epoxide number is 0.6-
0.75mol/100g
Preferably, the rubber powder is VAE rubber powder.VAE rubber powder is a kind of redispersable latex powder, and VAE rubber powder is a kind of vinegar
Vinyl acetate and tertiary ethylene carbonate-VeoVa or the binary or ternaries copolymer such as ethylene or acrylate, by being spray-dried
The modified emulsion powder arrived has good dispersibility, and when contacting rain water is dispersed into lotion again.VAE rubber powder, is usually used
It is mixed in mortar, improves mortar shock resistance type, durability and wearability.And in this application, it is to be used to prepare exterior coating,
After VAE rubber powder is added in the exterior coating, coating is easier in conjunction with the material of loam wall, meanwhile, it is capable to will
Existing loam wall carries out bonding sealing, improves the cohesiveness of existing loam wall.
Preferably, the antimildew and antibacterial agent is methyl 2-benzimidazolecarbamate.Mould inhibitor is for improving outside loam wall
Coat the anti-mold effect of coating.
Preferably, epoxy resin is epoxy resin E-51.Epoxy resin is the common used material of exterior coating, in the application
In, it is for cooperating with rubber powder, to improve the combination of the exterior coating and existing loam wall using epoxy resin E-51.
Preferably, the length of rice straw is 1-10mm, and wherein length is the part 1~5mm and the part 5~10mm of length
Weight content ratio is 1:2~2.5.Cracking resistance of the guide groove stalk as framework material, in addition to can be improved exterior coating coating
In addition, the combination fastness of coating and loam wall can also be improved by way of muscles and bones, in conjunction with existing loam wall.
Preferably, the average grain diameter mesh number of diatomite is 400-500 mesh.
The proportion of the water-based exterior wall paint are as follows: 70-78 parts of styrene-acrylate emulsion, benzoic acid modified alkyd tree
10-15 parts of rouge, 20-28 parts of unsaturated polyester resin, 7-9 parts of dioctyl phthalate, 1-3 parts of dicalcium powder, bentonite 2-5
It is part, 0.5-1.5 parts of basalt fibre, 2-5 parts of magnesia, 3-5 parts of zinc stearate, 5-10 parts of water, auxiliary agent 1-3 parts other, wherein
The acid value of unsaturated polyester resin is 65-78.Other auxiliary agents are exterior coating usual auxiliaries.
The application uses a part of water-based exterior wall paint coating as a whole, therefore applies to used water-based exterior wall
That expects is more demanding；Water-based exterior wall paint used by not only needing can be used alone, but also need the water-based exterior wall paint
Achieve the purpose that after the other components of the application mix and are used to combine with loam wall to current loam wall reparation.
The application uses above-mentioned proportion, and the water-based exterior wall paint of proportion composition, itself has comparable resistance to ag(e)ing
Can, and its anti-cracking performance, water resistance are preferable, the final diatomite exterior coating prepared based on the exterior coating,
There can be better dampproof effect；And its cohesive force is preferable, can cooperate with diatomite, be formed after solidification not easily to fall off
Globality surface layer, to improve the stability on loam wall surface.
The preparation method of the exterior wall diatomite paint of the existing cob wall of the repairing and reinforcement, preparation step are as follows:
(1) rice straw cleaning is drained, antimildew and antibacterial agent is added and is handled, is crushed by length requirement；
(2) half water-based exterior wall paint is taken, rubber powder, epoxy resin, diatomite is added and stirs evenly；
(3) (2) products therefrom is added in remaining water-based exterior wall paint and the rice straw handled well, be sufficiently stirred up to producing
Product.
Compared with prior art, the present invention beneficial effect is:
1, rice straw is utilized in the coating products, certain reinforcement effects is played to prepared compo, together
When, rice straw is added, waste utilization is more environmentally protective using material, and metope and the rural native soil landscape of formation hand over phase
It echoes.
2, after exterior coating diatomite, have that porosity is big, absorbability is strong, chemical property is stable, the spies such as wear-resisting, heat-resisting
Point can provide excellent surface property for coating, while increasing the wearability and mar-resistance of film, improve former metope
Waterproofness, heat resistance.
