The first aspect of the invention provides a breeding house which has the advantages of heat insulation, corrosion resistance, wear resistance and easy cleaning, and the breeding house comprises a breeding house body 1, an outer coating 2 and an inner coating 3.
Heat insulation and preservation,Corrosion-proof wear-resistant easy-to-cleanCultivation house
In one embodiment, the external coating 2 is formed by coating external paint on the outside of the breeding house body 1 by a method of airless spraying, roller coating and brush coating, and the internal coating 3 is formed by coating internal paint on the inside of the breeding house body 1 by a method of airless spraying, roller coating and brush coating, so that the breeding house with heat insulation, heat preservation, corrosion resistance, wear resistance and easy cleaning is prepared.
In a preferred embodiment, the external coating 2 is formed by applying an external paint to the outside of the breeding house body 1 by an airless spraying method, and the internal coating 3 is formed by applying an internal paint to the inside of the breeding house body 1 by an airless spraying method, so that the breeding house with heat insulation, corrosion resistance, wear resistance and easy cleaning is obtained.
Airless spray coating
The airless spraying refers to a spraying mode that a high-pressure plunger pump is used for directly pressurizing the coating to form high-pressure coating, and the high-pressure coating is sprayed out of a gun mouth to form atomized airflow to act on the surface of an object.
Water supply device
In one embodiment, a water supply device is installed inside the breeding house.
In a preferred embodiment, the water supply device is formed by connecting a water tank 4, a water supply pipe 5 and a water spray head 6 in sequence.
The water supply device is composed of a water tank 4, a water supply pipe 5 and a water spray head 6, and is in a communicated state when in use.
In the invention, the interior of the breeding house has the function of easy cleaning, dirt in the breeding house can be cleaned well through the water supply device, so that the interior of the breeding house can be kept in a clean state, and the interior of the breeding house has good waterproofness, so that the interior coating 3 cannot be damaged due to the cleaning of the interior with water.
Exterior coating
In one embodiment, the raw materials of the external coating comprise, by weight, 75-85 parts of D906 hyperbranched resin, 0.8-1.5 parts of pH regulator, 15-20 parts of solvent, 5-8 parts of heat preservation auxiliary agent, 4-7 parts of silicon nano additive, 0.3-0.6 part of preservative and 2-4 parts of auxiliary agent.
In a preferred embodiment, the raw materials of the exterior coating material further comprise a film-forming aid, and the weight of the film-forming aid is 0.5 to 0.8% of the weight of the exterior coating material.
In one embodiment, the exterior coating is prepared according to the following method:
(1) stirring a solvent, a heat-preservation auxiliary agent, a silicon nano additive, a preservative, an auxiliary agent and a film-forming auxiliary agent in a high-speed dispersion machine at the rotating speed of 1800-2000r/min for 30-40min to obtain a dispersion liquid A;
(2) adding a pH regulator and D906 hyperbranched resin into the dispersant A, and stirring for 10-20min in a high-speed dispersion machine at the rotating speed of 1800 plus 2000r/min to obtain the external coating.
D906 hyperbranched resin
The D906 hyperbranched resin was purchased from the TGA group of Australia.
pH regulator
In one embodiment, the pH adjusting agent is selected from at least one of the Dow pH adjusting agents AMP-95, the amine Vantantex pH adjusting agent, the Vantex-T pH adjusting agent.
The pH regulator selected in the invention is a chain-shaped alcohol amine regulator, and hydrogen bonds exist among molecules, so that the pH regulator can be well dispersed in the system.
In a preferred embodiment, the pH regulator is selected from DOW pH regulator AMP-95, and the applicant has unexpectedly found that DOW pH regulator AMP-95 not only can improve the dispersion stability of the heat preservation auxiliary agent and the silicon nano additive in the system, and adjust the pH value of the system, but also can improve the adhesion of the external coating 2 on the breeding house body 1, probably because the propanol is on the main chain molecule of DOW pH regulator AMP-95, and can better interact with the D906 hyperbranched resin in the spatial structure, so that a certain three-dimensional spatial structure is formed, and thus the DOW pH regulator AMP-95 can better adhere to the outside of the breeding house body 1.
Film forming aid
In one embodiment, the coalescent is coalescent OE-300 in an amount of 0.5 to 0.8% by weight of the total external coating.
The film-forming assistant OE-300 is an environment-friendly film-forming assistant, has good dispersing performance in a system, and can be well compatible with water, DMF and diethylene glycol monobutyl ether in a solvent, so that an external coating can well form a coating. In addition, a good film forming effect can be achieved without adding too much film forming aid in the system, the adhesion and the heat insulation performance of the external coating 2 cannot be influenced due to instability of the external coating caused by excessive addition of the film forming aid, and the film forming performance of the external coating is possibly improved due to interaction between hydroxyl in the film forming aid OE-300 and Si-OH in the silicon nano additive.
Solvent(s)
In one embodiment, the solvent comprises water.
The system is a water-based system, and other raw materials can be well dispersed in the system by selecting water as a solvent.
In a preferred embodiment, the solvent further contains DMF and diethylene glycol monobutyl ether, wherein the weight of the DMF is 12-15% of the weight of the water, and the weight of the diethylene glycol monobutyl ether is 5-7% of the weight of the water.
The applicant has found that, surprisingly, when a certain amount of DMF is contained in the solvent, the performance of the outer coating 2 is better, probably because the dispersibility of some raw materials in the system in water is not good, but DMF can increase the dispersibility of the raw materials in the system by mutual solubility with water and then synergistic interaction with diethylene glycol monobutyl ether, so that the performance of the outer coating 2 is better, and an amide group in DMF can interact with an amide group in the DOW pH regulator AMP-95, and an alcoholic hydroxyl group in diethylene glycol monobutyl ether can interact with an alcoholic hydroxyl group in the film forming aid OE-300 to form a certain network structure, so that the outer coating has good wettability, and the adhesion of the outer coating 2 is increased by virtue of hydrogen bonds and van der waals force.
Heat-insulating auxiliary agent
In one embodiment, the heat preservation auxiliary agent is SBA-15 molecular sieve and/or nano talcum powder.
In the system of the invention, the heat preservation and insulation performance of the external coating 2 is enhanced by the mutual synergistic effect of the heat preservation auxiliary agent and the silicon nano additive.
In a preferred embodiment, the heat preservation auxiliary agent is a mixture of an SBA-15 molecular sieve and nano talcum powder, and the weight ratio of the SBA-15 molecular sieve to the nano talcum powder is 1: 1.
the applicant has found that when the heat-insulating auxiliary agent is a mixture of SBA-15 molecular sieve and nano talcum powder, the heat-insulating property of the external coating 2 is better, the adhesion of the external coating 2 is better, and the defect of odorous paint brought by the Dow pH regulator AMP-95 can be reduced. Probably because the SBA-15 molecular sieve is a highly ordered mesoporous molecular sieve which can absorb some odors in a system, a large number of silicon hydroxyl groups are arranged in the SBA-15 molecular sieve, the nano talcum powder is actually a particle with negative charges, and under the action of a solvent in the system, the nano talcum powder, the SBA-15 molecular sieve and the silicon nano additive can form a net structure to ensure that an external coating is stably attached to the breeding house body 1, and a higher double-layer potential can be shown on the surface of the heat-insulating auxiliary agent, so that when the external coating is in contact with the breeding house body 1, electron transfer occurs in different electron layer structures, and the adhesive force of the external coating 2 is improved.
The SBA-15 molecular sieve is purchased from Zhuran environmental protection science and technology Co.
The nano talcum powder is purchased from a Chuangwei mineral product processing factory in Lingshou county.
Silicon nano additive
In one embodiment, the silicon nano-additive is a silica microsphere.
The silicon dioxide microspheres are modified with silicon hydroxyl and carboxyl on the surfaces, and can be connected with a heat preservation auxiliary agent and D906 hyperbranched resin through covalent bonds, so that efficient radiation heat exchange is realized, the heat flow density is adjusted, and the heat preservation and insulation effects are achieved.
In a preferred embodiment, the silica microspheres have an average particle size of 100-150 nm.
The applicant finds that in the system, when the average particle size of the silica microspheres is 100-150nm, the performance of the external coating 2 is better, probably because when the average particle size of the silica microspheres is larger than 150nm, the dispersibility of the silica microspheres in the system is not good, and thus various performances of the external coating 2 are affected; when the average particle size of the silica microspheres is less than 100nm, the adhesive force of the external coating 2 is reduced, probably because the charge synergistic effect between the silica microspheres and the heat preservation auxiliary agent is not good, so that a double-charge layer is not easily formed when the silica microspheres contact the outside of the breeding house body 1, and the adhesive force of the external coating 2 is reduced.
The silica microspheres were purchased from korea ltd.
Auxiliary agent
In one embodiment, the auxiliaries include defoamer BKY024 (silicone), leveling agent TEGO Glide440, dow thickener DR 72, the weight ratio of defoamer BKY024, leveling agent TEGO Glide440, dow thickener DR 72 is 1.2: 1.5: 1.
the applicant found that when the auxiliary agents are defoamer BKY024, leveling agent TEGO Glide440 and Dow thickener DR 72, and the weight ratio of defoamer BKY024, leveling agent TEGO Glide440 and Dow thickener DR 72 is 1.2: 1.5: 1, the performance of the outer coating 2 is better, probably because this condition is better synergy of the coagent with the D906 hyperbranched resin in the present system.
Interior coating
In one embodiment, the interior includes a coating a component and a B component.
In one embodiment, the raw materials of the component A comprise, by weight, 60-80 parts of hexamethylene diisocyanate trimer and 20-40 parts of modified ester auxiliary agent; the component B comprises 40-50 parts of polyaspartic acid resin, 15-20 parts of modified ester auxiliary agent, 7-10 parts of pigment, 8-12 parts of inorganic auxiliary agent, 0.5-0.8 part of dispersing agent, 1-1.5 parts of flatting agent and 0.8-1 part of defoaming agent.
In a preferred embodiment, the weight ratio of component a to component B is (7-9): (11-15).
When in use, the component A and the component B are mixed uniformly and then can be used.
In one embodiment, the internal coating is prepared according to the following method:
(1) stirring hexamethylene diisocyanate tripolymer and the modified ester auxiliary agent in a high-speed dispersant at the rotating speed of 1500-1800r/min for 10-20min to obtain a component A;
(2) stirring the polyaspartic acid resin, the modified ester auxiliary agent, the pigment, the inorganic auxiliary agent and the dispersing agent in the high-speed dispersing agent at the rotating speed of 1800 plus 2000r/min for 10-20min, adding the flatting agent and the defoaming agent, and continuously stirring for 20-30min to obtain the component B.
