Description
Technical field
The invention belongs to building decoration technology field, and in particular to a kind of finishing agent and preparation method thereof.
Background technology
The increase year by year of continuous improvement and concrete surface no longer plastering engineering with building standard, building trade is not only
Start large-scale use template, and requirement to template quality also more and more higher.Early stage architectural engineering is substantially directly to make
With glued laminin plate as template, but because plain plate water resistant and anti-wear performance are poor, therefore it is only 10~15 that it, which reuses number of times,
It is secondary, it is sometimes even lower.In order to change this situation, improve the performance of building template, it is necessary to which the surface of template is entered
Row processing.
CN1386811A discloses a kind of paint for building shuttering, and 230~270kg of isocyanates, two are contained during the coating is per ton
50~80kg of butyl ester, 0.5~1kg of phosphoric acid, 33070~100kg of polyethers, 63520~49kg of polyethers, 400~540kg of dimethylbenzene.
The coating has excellent adhesive force, hardness, toughness and alkaline-resisting, heat-resisting, anti-wear performance, also with excellent demolding performace, fits
Close the releasing agent for making the various moulds such as wooden model, the surface conditioning agent of bamboo mould and punching block.
CN101830032A, which is disclosed, a kind of can be used for preventing or reducing the coagulation that concrete and template surface are mutually bonded
Native long-acting mould release agent and preparation method thereof, releasing agent includes two kinds of preparations of template paint host and adhesive agent, wherein template paint host
It is main that the technique systems such as mixing, filtering are passed through by epoxy resin or unsaturated polyester resin or acrylic resin, solvent, additive
Into.In use, template surface is wiped twice with adhesive agent first, after brushing template paint host 1~2 time again after liquid level drying,
Can be in one layer of smooth surface with smooth feel and with sliding properties of template surface formation after its solidification is dried.
Commercially available building finishing agent domestic at present can reach the requirement that building template is used in some performances, but presence contains admittedly
The problem of amount is relatively low, organic volatile is more.Additionally generally existing solidification or the time required to drying it is longer, wearability is poor,
Performance is unstable and shortcoming of biocidal property, and these can all be applied to a thick film brings difficult and bring very big dirt to environment
Dye, gives enterprise scale production increase difficulty.Therefore, the problem of solving finishing agent wearability and poor biocidal property, can be further
Promote advancing for building finishing agent.
The content of the invention
Present invention mainly solves technical problem, the accumulation of heat existed in the curing process for current polyurethane injecting paste material
Temperature is high, and easily there is provided a kind of injecting paste material and preparation method thereof for the defect of generation dieseling.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of finishing agent, includes the raw material of following parts by weight：

3 parts of emulsifying agents and 60~70 parts of butanone.
Described epoxy resin is one or both of epoxy resin E-44, epoxy resin 601.
Described initiator is the one or more in potassium peroxydisulfate, lauroyl peroxide, TBHP.
Described modified filler is obtained by following steps：
（1）After 200~300g graphite, 100~200g sericites are crushed, obtain mixed-powder, by mixed-powder and 600~
800mL biogas slurries sealing and fermenting 8~10 days at 35~45 DEG C, obtain tunning, and tunning is sterilized, centrifuged, is sunk
Starch；
（2）It is that 25% zinc nitrate solution is reacted after 60~90min at 60~70 DEG C by sediment and 500~600mL mass fractions
Filtering, obtains filter residue, after filter residue, 20~30g azanols and 500~600mL mass fractions are mixed for 15% sodium hydroxide solution,
React after 1~2h and filter at 70~80 DEG C, obtain filter cake, filter cake is calcined into 2~3h at 400~500 DEG C, then cool down, obtain
Modified filler.
Described emulsifying agent is one or both of NPE, ethoxylated dodecyl alcohol.
A kind of preparation method of finishing agent, specific preparation process is：
（1）Match by weight, progress takes raw material；
（2）Add the raw material into reactor, in 75~85 DEG C of 3~4h of stirring reaction, then cool down, obtain finishing agent.
The beneficial effects of the invention are as follows：
The present invention enters mixed-powder and biogas slurry mixed fermentation using the material secreted in microorganism growth process to mixed-powder
Row corrodes micro- corruption, and micropore is produced on mixed-powder surface and the polar organic matter containing carboxyl is loaded, is conducive in mixed-powder
Surface deposited metal layer, followed by the carboxyl chelated mineral zinc ion on mixed-powder surface, makes zinc ion is even equal to be attached to
Mixed-powder surface, then carry out being reduced into zinc simple substance by zinc ion with the azanol of strong reducing property and closely anchor at mixed-powder table
In face and its micropore, finally calcined again, the oxidation of zinc simple substance is obtained zinc oxide, zinc oxide has extremely strong bactericidal
Can, and graphite and sericite are under Frotteurism, can strengthen wearability along brilliant interformational sliding.
