Description
Technical field
The present invention relates to antirust paint field, and in particular to a kind of phenolic group antirust paint.
Background technology
It is most using epoxy zinc-rich paint that industrial antirust paint was used in recent years come protect metal, due to the density of metal zinc
It is bigger, in order to not make zinc powder settling or slow down the sinking speed of zinc powder, it is necessary to add a certain amount of sagging inhibitor in paint；It is anti-settling
The viscosity of the addition paint of agent is consequently increased, and will select the resin of small-molecular-weight as much as possible when selecting polyamide
(E44)；In order to meet brushability during construction, substantial amounts of solvent is added into paint, solvent seriously endangers worker's during construction
Health, paint in the drying process solvent evaporate into air pollute environment, solvent make improve construction cost；Small molecule
The fragility of paint film is big after amount resin solidification, and paint film is easily cracked or come off greatly in temperature change for metal heat-expansion shrinkage system.Phenolic aldehyde is prevented
Rust paint is by phenolic resin, antirust material, pigment, the clout such as No. 200 industrial naptha, cobalt, manganese, lead, by grinding, paint, is produced
A kind of priming paint to metal surface antirust function, be characterized in good antirust property water-tolerant, can be used as fat glue class, alcohol acids
The priming paint of finish paint.But in the production and use process, safety coefficient is low, VOC emission amount is big, in transport, use, production process
It is inflammable, it is explosive, bring great inconvenience.It is an object of the invention to provide a kind of phenolic group antirust paint of environment-friendly type, reduce VOC's
Discharge.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of phenolic group antirust paint, brushing is functional, cost is low, to ring
Border is friendly.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of phenolic group antirust paint, it is characterised in that bag
Include the raw material of following parts by weight：Phenol-formaldehyde resin modified 20-30 parts, epoxy resin 10-20 parts, modified meerschaum powder 10-20 parts, change
Property straw ash 1-5 parts, rust resisting pigment 10-15 parts, filler 10-20 parts, fatty acid sorbitan 1-2 parts, plasticizer 0.5-1, solvent
10-30 parts；
The preparation method of phenol-formaldehyde resin modified, by phenol waste residue, formaldehyde, siritch, pentaerythrite, maleic anhydride, PbO, ZnO
And catalyst, polymerisation is carried out at 200-220 DEG C, when resin viscosity reaches 10-20s (form pipe/25 DEG C), solid part 50 ±
When 2%, acid number≤10mg KOH/g, diluted with mixed solvent, filtered after stirring；
Epoxy resin be epoxide equivalent be 150-500 propane type epoxy resin of di phenolic group, phenolic aldehyde multi-epoxy resin or more
Hydroxyl phenols diglycidyl ether type epoxy resin；
The preparation method of described modified meerschaum powder is first uses 15-20% salt acid soak sepiolite 1-2 hours, standing,
Clarification, centrifugation, solid are washed with water to neutrality, after drying, add the VTES equivalent to solid weight 3-5%
Agitating is uniform, drying, is ground into powder；
Described modified straw ash preparation method is that straw ash is added into 10-15% sodium hydroxide solutions to soak 3-4 hours
Afterwards, pull out, water content 2-3% be dried under temperature 40-45 degree, after add 3-4% chlorinated paraffins immediately and be well mixed, then,
Add 1-2% river sands and 3-5% carboxymethyl celluloses, mixing granulation；
The rust resisting pigment is modified laterite, and preparation method adds for first titanate coupling agent is dissolved in dimethylbenzene
Laterite uniform stirring 2h at room temperature, prevent overnight.
Further, the filler is barium sulfate, talcum powder or calcium carbonate.
Further, the plasticizer is trioctyl trimellitate (TOTM).
Further, the solvent is one or more of mixing in ethanol, ethylene glycol, butanediol, amylalcohol.
Preferably, include the raw material of following parts by weight：30 parts of phenol-formaldehyde resin modified, 20 parts of epoxy resin, modified Hai Pao
10 parts of stone flour, 1 part of modified straw ash, 10 parts of rust resisting pigment, 10 parts of filler, 1 part of fatty acid sorbitan, plasticizer 0.5, solvent 20
Part.
The advantage of the invention is that：
1st, processing, and novolak resin are modified using caused waste residue in phenols production process, it is environmentally friendly,
Twice laid, and without pre-treatment, directly carry out polymerisation, fundamentally solve the problems, such as waste residue environmental pollution；
2nd, rust resisting pigment is used as with linking compounding using laterite, all instead of iron oxide, reduces the cost of antirust paint；
3rd, it is good to be complexed power for phenolic antirust paint of the invention and metal surface, antirust long lifespan, fast drying, easy to use, and
And cost is low, high temperature resistant, can direct spraying or Xu brush in the metal surface for having rust, and in a low temperature of -24 DEG C still can as usual make
Industry, can be widely applied to bridge, rich, container, ship, steel sash, plant equipment and pipeline etc. need antirust, the metal of derusting
On foundry work part.
