Specific embodiment
Embodiment of the present invention is described in detail below in conjunction with embodiment, but those skilled in the art will Understand, the following example is merely to illustrate the present invention, and is not construed as limiting the scope of the invention.It is not specified in embodiment specific Condition person, the condition suggested according to normal condition or manufacturer carry out.Reagents or instruments used without specified manufacturer is The conventional products that can be obtained by commercially available purchase.
Uncured water-repellent paint below for the embodiment of the present invention and preparation method thereof is specifically described：
The raw material for preparing the uncured water-repellent paint of anti-hung type includes the following components counted in parts by weight：Modified pitch 40~ 60 parts, 8~15 parts of whisker, 2~6 parts of graphene, 11~15 parts of softening agent, 11~15 parts of inorganic powder, 0.5~1 part of elastomer, 2~3 parts of binding agent.It improves in example, raw material includes the following components counted in parts by weight：43~54 parts of modified pitch, whisker 10 ~11 parts, 3~5 parts of graphene, 12~14 parts of softening agent, 12~14 parts of inorganic powder, 0.7~0.9 part of elastomer, binding agent 2 ~3 parts, 6~11 parts of thixotropic agent.
Modified pitch for example can be rubber asphalt (rubber asphalt).It can be that waste tire first is processed into rubber Powder, then be combined in certain size grading ratio, while add a variety of high polymer modifying agent, and in abundant mix Under heating condition, the cementing material of modified pitch that is formed after being reacted with the abundant swell of matrix pitch.The performance of modified pitch is for example Can be that 1.4~1.5Pa.S of viscosity under the conditions of 160 DEG C, the elasticity at 25 DEG C restore more than 80%, 60 DEG C of softening point or more.Or Person, modified pitch can also be the pitch using polyurethane or styrene analog thermoplastic elastomer modification.
Preparation method includes the following steps：
First step, will softening agent add in modified pitch in, heating 80~100 DEG C and constant temperature with 600~800r/min's Speed stirs 30~40 minutes, adds elastomer so that modified pitch swelling softening and cooled to room temperature, are softened Pitch.
In the case where heating the collective effect with softening agent, modified rubber can be made adequately to be softened, to allow elasticity Body is entered sufficiently into pitch, and both makes preferably to combine, at the same also when pitch property be adjusted and with more preferable performance.
Wherein, softening agent can include but is not limited to naphthenic oil, aromatic naphtha.Elastomer can be including but not limited to thermoplasticity One or more combinations in butadiene-styrene rubber, thermoplastic polyurethane rubber, rosin resin, terpene resin and Petropols.Or Person, elastomer can also be selected as one or more in SBS rubber grains, SBR rubber particle, NBR rubber particle.
Second step mixes thixotropic agent, whisker, graphene and inorganic powder, then stirred and evenly mixed with binding agent, obtains Powder materials.
In the more excellent example of the present invention, after obtaining powder materials, powder materials are dried be beneficial to it is uncured anti- The preparation of water paint and its holding of performance and improvement.As a kind of specific example, powder materials are carried out dehydrating to containing Water rate is in below 0.1wt%, it is preferable that moisture content is in 0.08wt% hereinafter, it is highly preferred that below 0.05wt%.Dried powder The mode of material is there are many selection, for example, centrifugal dehydration, thermal dehydration, dehydrating agent washing etc..In the present embodiment, drying means It is selected as negative pressure heat dehydration.The method being dehydrated to powder materials is negative pressure heat dehydration.Negative pressure heat dehydration includes：50~ 70 DEG C, heat 1-2 hours under the negative pressure of 0.5~1MPa, then heated 30 minutes under 100~120 DEG C, the negative pressure of 1.5~2MPa.
Wherein, whisker can select calcium carbonate crystal whisker, ZnOw, ester exchange at phosphorus etc..It can antibacterial, and also Filler and toughener can be used as, improves the structural strength of uncured water-repellent paint.Whisker is formed by high-purity crystal growth Micro/nano level staple fiber.Its mechanical strength is equal to the intensity that adjacent interatomic force generates.The height-oriented structure of whisker is not High intensity, high-modulus and high elongation rate are only made it have, but also there is electricity, light, magnetic, dielectric, conduction, superconduct property.Separately Outside, whisker can be chosen for organic crystalline palpus.For example, cellulose whiskers, poly- (4- hydroxyls benzene methyl) whisker etc..When using organic During whisker, in a manner that heat is mixed and stirred, whisker, graphene and inorganic powder can be better mixed, also be more easy to and elasticity Body, pitch combine, to improve the ductility of waterproof material and anti-shearing active force performance.Preferably, whisker can be with vulcanization Agent (such as sulphur) uses together, and the two synergistic effect can promote the polymerizable molecular in asphalitine to crosslink, and realize to waterproof The further modified optimization of modified pitch in material, such as temperature stability, ductility.
Graphene is layer structure, and with certain lubricity.It can occur to a certain extent between graphene layer Mutually sliding.Therefore, the ductility of waterproof material may be improved using graphene.
Inorganic powder can be metal powder or non-metal powder or metal powder and non-metal powder Mixture.In a kind of example, inorganic powder includes one or more in zinc oxide, titanium oxide, talcum powder, montmorillonite powder.
Preferably, in some instances, the raw material for preparing uncured water-repellent paint further includes 3~8 parts of ferrite, and iron oxygen Body is powder.Be by the technique of uncured water-repellent paint, ferrite in the presence of in powder materials.Ferritic use can Improvement is played the role of with the performance to waterproof material.Ferrite can be sent out under the action of alternating magnetic field by hysteresis Raw fuel factor and generate heat, realize self-heating.Therefore, when using containing ferritic uncured water-repellent paint, pass through Under alternating magnetic field and the collective effect of heating, waterproof material is molten into fluid, even liquid condition, and then be used to bond Base.
Soft pitch is heated to 60~80 DEG C and keeps the temperature 0.5~1 hour by third step, then powder materials are mixed into simultaneously play Strong stirring is then heated to 160~170 DEG C, and is ground 1~2 hour by colloid mill.
Based on above process, a kind of uncured water-repellent paint of resist sagging type is made into.
Following manner progress may be used in the construction method of the uncured water-repellent paint of resist sagging type：Treat base cleaning finish with Afterwards, the uncured water-repellent paint of appropriate amount is heated and expected, it is to be achieved when scratching state, it is uniformly sprayed with scraper, cooling is Into.
