Description

A kind of zinc molybdate nanometer rods combined high temperature fluid sealant
Technical field
The invention belongs to encapsulant technical field is and in particular to a kind of zinc molybdate nanometer rods combined high temperature fluid sealant.
Background technology
Fluid sealant is used for the sealing of the field such as material, chemical industry, machinery container, valve and the various seam of pipeline or hole, can To stop gas, liquid and solids passage, thus playing the function of sealing.Existing multinomial patent discloses joining of fluid sealant at present Side.National inventing patent " a kind of high-temperature seal adhesive and preparation method thereof " (national inventing patent application number： 200810058057.1) disclose with PVC paste shape resin, alkyd resin, soybean oil, stabilizer, liquid white oil, soda foaming agent As primary raw material prepared a kind of meet that food safety, sealing property be excellent and sterilizing time reach 45 minutes for sealing The fluid sealant of food, can use at a temperature of less than 128 DEG C.National inventing patent " anticorrosive high temperature sealing glue " (country Application for a patent for invention number：97118833.5) disclose with F46 novolac epoxy resin, NA anhydride, end carboxyl nitrile (HTBN) 40, gather Tetrafluoroethene, calcium fluoride, lithium fluoride, butanone-2, normal propyl alcohol, toluene and Ketohexamethylene have prepared a kind of corrosion-proof high-temp for raw material Fluid sealant, is less than 200 DEG C using temperature.
Due to developing rapidly of modern industry, the requirement more and more higher to fluid sealant, in some special occasions, such as high temperature Container, pipeline and valve field, fluid sealant is in addition to needing to have bonding and sealing function in addition it is also necessary to have good resistance to height Warm, ageing-resistant, corrosion-resistant, heat stability, the several functions such as fire-retardant and water-fast, and existing fluid sealant be difficult to meet above will Ask.
Content of the invention
The invention aims to solution problem above, using zinc molybdate nanometer rods, polyvinyl acetate emulsion, unsaturation Polyester resin and methane-siliconic acid, as raw material, are desirably to obtain and have good sealing, high temperature resistant, ageing-resistant, corrosion-resistant, hot steady The zinc molybdate nanometer rods combined high temperature fluid sealant of qualitative, fire-retardant and water resistance.
The mass percent composition of zinc molybdate nanometer rods combined high temperature fluid sealant provided by the present invention is as follows：
Zinc molybdate nanometer rods 35-50%, polyvinyl acetate emulsion 20-25%, unsaturated polyester resin 20-25%, methyl Silicic acid 10-15%.
Further, a diameter of 30-100nm of described zinc molybdate nanometer rods, length is 1-5 μm.
The concrete preparation method of zinc molybdate nanometer rods provided by the present invention is as follows：
Using sodium molybdate, zinc sulfate as raw material, water is solvent, and wherein sodium molybdate and the mol ratio of zinc sulfate are 1:1, by molybdenum Sour sodium, zinc sulfate are placed in after uniformly being mixed with water in reaction vessel and seal, and in temperature 120-200 DEG C, are incubated 12-48h, wherein Sodium molybdate is not more than the 50% of water weight with the weight of zinc sulfate.
The concrete preparation method of zinc molybdate nanometer rods combined high temperature fluid sealant provided by the present invention is as follows：
Weigh zinc molybdate nanometer rods, polyvinyl acetate emulsion, unsaturated polyester resin and methane-siliconic acid according to mass ratio, Then polyvinyl acetate emulsion, unsaturated polyester resin and methane-siliconic acid are mixed, be subsequently added into zinc molybdate nanometer rods, machinery stirs Mix 4-8 hour mix homogeneously, finally give zinc molybdate nanometer rods combined high temperature fluid sealant.
Compared with prior art, the present invention has following technique effect：
1st, using corrosion-resistant, dystectic zinc molybdate nanometer rods as filler, polyvinyl acetate emulsion, unsaturation are poly- for the present invention As adhesive, methane-siliconic acid, as waterproofing agent, can prepare zinc molybdate nanometer rods combined high temperature fluid sealant to ester resin.This Fluid sealant has good sealing, high temperature resistant, corrosion-resistant, ageing-resistant, thermally-stabilised, fire-retardant and water resistance, in material, change The high temperature such as work, machinery, the container of Korrosionsmedium, valve and seal for pipe joints aspect have a good application prospect.
2nd, the zinc molybdate nanometer rods fusing point that the present invention adopts is high, corrosion resistance is strong, good stability and pollution-free, poly-vinegar acid second Alkene emulsion, unsaturated polyester resin and methane-siliconic acid are the raw materials of batch production, it is possible to achieve zinc molybdate nanometer rods combined high temperature The batch preparation of fluid sealant.
