Description
Technical Field
The invention relates to the technical field of photovoltaics, in particular to an adhesion promoter and a BIPV system.
Background
BIPV technology is a technology that integrates solar power (photovoltaic) products into buildings. Among them, photovoltaic roofing is an important application of BIPV technology. The roofing of industrial plants is generally of profiled sheet metal construction. The metal plate generally includes a substrate, a plating layer covering a surface of the substrate, and a fingerprint resistant layer provided on a surface of the plating layer.
When the BIPV system is manufactured, the photovoltaic module and the metal plate are bonded together through structural adhesive. In the bonding process, the metal plate and the structural adhesive have poor bonding effect due to the problems of uneven surface, low surface energy, fingerprint resistant layer, grease and the like of the metal plate.
Disclosure of Invention
The invention aims to provide an adhesion promoter and a BIPV system, so that a metal plate and a structural adhesive can be easily and firmly bonded together.
In a first aspect, the present invention provides an adhesion promoter. The adhesion promoter comprises: silane polymer, a cross-linking agent and a catalyst, wherein the polymerization degree of the silane polymer is 2-10; the mass ratio of the silane polymer to the cross-linking agent to the catalyst is (2-10): (10-20): (0.1-5).
When the technical scheme is adopted, the adhesion promoter contains the silane polymer, and the polymerization degree of the silane polymer is 2-10. In this case, the molecular weight of the silane-based polymer is small. When the adhesion promoter is coated on the metal plate, the silane polymer with small molecular weight can quickly wet the surface of the metal plate, so that the problem of too slow wetting when the metal plate is adhered with the structural adhesive is avoided. The silane polymer and the cross-linking agent in the adhesion promoter can undergo pre-crosslinking reaction under the catalytic action of the catalyst to generate a microscopic network structure, so that the adhesion promoter has higher cohesive strength. In addition, the silane polymer, the cross-linking agent and the catalyst in the mass ratio of (2-10) - (10-20) - (0.1-5) have proper pre-crosslinking reaction speed and degree, so that the adhesion promoter has good cohesive strength, and the problems that the pre-crosslinking reaction is completed too fast before the structural adhesive is coated and the strength of the adhesion promoter is influenced by the low pre-crosslinking reaction degree are solved. After the pre-crosslinking reaction of the adhesion promoter is finished, the surface of the adhesion promoter still has more active groups, so that the adhesion promoter, the structural adhesive and the metal plate can form more chemical bonds. And the active group of the adhesion promoter can form a firm cross-linking structure with the structural adhesive to firmly connect the structural adhesive and the metal plate.
On the basis of quick wetting, the adhesion promoter disclosed by the invention can generate a network structure in the adhesion promoter, so that the network structure has higher cohesive strength, and the adhesion strength between a metal plate and a structural adhesive can be improved; on the other hand, the surface of the composite material has more active groups, and more chemical bonds can be formed with the structural adhesive and the metal plates on the two sides respectively. Therefore, the adhesion promoter can quickly and firmly bond the metal plate and the structural adhesive together.
In some possible implementations, the silane-based polymer includes one or more of polydiaminodisilane and polydimethylsiloxane. At this time, under the condition of low polymerization degree, polydiaminodisilane and polydimethylsiloxane can form a complete and firm network structure under the crosslinking reactivity, and more active groups can form stable chemical bonds with the metal plate and the structural adhesive.
In some possible implementations, the cross-linking agent includes one or more of a tri-functional silicone cross-linking agent, a tetra-functional silicone cross-linking agent. In this case, the crosslinking agent has a large number of functional groups capable of participating in the crosslinking reaction. When the cross-linking agent and the silane polymer are subjected to cross-linking reaction, a stable three-dimensional network structure can be formed. Moreover, the crosslinking agents facilitate the reaction of the silane-based polymer with the structural adhesive.
In some possible implementations, the catalyst is an organotin-based catalyst. The reaction speed of the pre-crosslinking reaction can be regulated and controlled by the organic tin catalyst, so that a complete and stable network structure is ensured to be formed, and the adverse effect of the slow reaction of the silane polymer and the crosslinking agent on the strength of the adhesion promoter is avoided.
In some possible implementations, the crosslinking agent is methyltriethoxysilane. At this time, a stable network structure can be formed among the methyltriethoxysilane, the polydiaminodisilane and the polydimethylsiloxane, which is beneficial to improving the cohesive strength of the adhesion promoter.
In some possible implementations, the adhesion promoter further includes a coupling agent, and the coupling agent includes one or more of an aminosilane coupling agent and an epoxysilane coupling agent. At the moment, the addition of the coupling agent can participate in the pre-crosslinking reaction, increase active groups in the pre-crosslinking reaction process and improve the reaction completion degree of the pre-crosslinking reaction and the stability of a network structure produced by the pre-crosslinking reaction; on the other hand, active groups of the adhesion promoter after the pre-crosslinking reaction can be increased, so that the number of chemical bonds formed between the adhesion promoter and the metal plate and between the adhesion promoter and the structural adhesive can be increased, and the strength of the adhesion promoter for connecting the metal plate and the structural adhesive can be further improved.
In some possible implementations, the adhesion promoter further includes a solvent having a polarity less than or equal to 5. In this case, the solvent has a low polarity, and is close to the polarity of the paraffin contained in the fingerprint-resistant layer, and can dissolve the paraffin or the like on the surface of the metal plate, thereby improving the wetting effect of the adhesion promoter on the surface of the metal plate and increasing the wetting speed. And after the paraffin and the like on the surface of the metal plate volatilize along with the solvent, the active groups on the surface of the metal plate can be released, so that the number of chemical bonds formed between the metal plate and the adhesion promoter is further increased, and the connection strength between the metal plate and the adhesion promoter is improved.
In some possible implementations, the solvent is an alkane compound. At this time, the silane compound has low polarity, not only can well dissolve substances such as paraffin and the like on the surface of the metal plate, but also is easy to volatilize, and is beneficial to reducing substances such as paraffin and the like on the surface of the metal plate by utilizing the volatilization process.
In some possible implementations, the solvent includes one or more of diethyl ether, chloroform. The ether and the chloroform can quickly dissolve the paraffin, and the ether is very easy to volatilize at normal temperature, so that the paraffin on the surface of the metal plate can be quickly reduced in the process of coating the adhesion promoter.
In some possible implementations, the adhesion promoter includes, in mass fraction: 50 to 100 portions of silane polymer, 10 to 20 portions of cross-linking agent, 0.9 to 10 portions of coupling agent, 0.1 to 5 portions of catalyst and 20 to 200 portions of solvent. At this time, the silane polymer, the crosslinking agent, the coupling agent, the catalyst and the solvent in the ratio can be well mixed. More solvents can firstly contact with the metal plate to dissolve substances such as paraffin and the like on the surface of the metal plate and release active groups; then the silane polymer, the cross-linking agent and the catalyst are contacted with the metal plate, and the silane polymer, the cross-linking agent and the catalyst form a chemical bond with active groups on the surface of the metal plate and simultaneously carry out pre-cross-linking reaction inside the metal plate to form a network structure. After the structural adhesive is coated, the active groups on the surface of the adhesion promoter and the structural adhesive form chemical bonds to complete the crosslinking of the adhesion promoter, so that the metal plate and the structural adhesive are easily and firmly bonded under the action of the adhesion promoter.
In a second aspect, the present invention provides a BIPV system. The BIPV system comprises a metal plate, a structural adhesive and the adhesion promoter described in the first aspect or any one of the possible implementations of the first aspect; the metal plate and the structural adhesive are bonded together through the adhesion promoter.
The benefits of the BIPV system provided by the second aspect may be obtained by reference to the benefits of the adhesion promoter described in the first aspect or any implementation of the first aspect, which are not further stated herein.

For example, at least one (one) of a, b, or c, may represent: a, b, c, a and b combination, a and c combination, b and c combination, or a, b and c combination, wherein a, b and c can be single or multiple.
The embodiment of the invention provides an adhesion promoter. The adhesion promoter is used for connecting a metal plate and a structural adhesive.
The adhesion promoter includes: silane-based polymers, crosslinking agents and catalysts. Wherein the polymerization degree of the silane polymer is 2 to 10. The mass ratio of the silane polymer to the cross-linking agent to the catalyst is (2-10): (10-20): (0.1-5).
Based on the composition of the adhesion promoter, the adhesion promoter contains a silane-based polymer, and the polymerization degree of the silane-based polymer is 2 to 10. In this case, the molecular weight of the silane-based polymer is small. When the adhesion promoter is coated on the metal plate, the silane polymer with small molecular weight can quickly wet the surface of the metal plate, so that the problem of too slow wetting when the metal plate is adhered with the structural adhesive is avoided. The silane polymer and the cross-linking agent in the adhesion promoter can undergo pre-crosslinking reaction under the catalytic action of the catalyst to generate a microscopic network structure, so that the adhesion promoter has higher cohesive strength. In addition, the silane polymer, the cross-linking agent and the catalyst in the mass ratio of (2-10) - (10-20) - (0.1-5) have proper pre-crosslinking reaction speed and degree, so that the adhesion promoter has good cohesive strength, and the problems that the pre-crosslinking reaction is completed too fast before the structural adhesive is coated and the strength of the adhesion promoter is influenced by the low pre-crosslinking reaction degree are solved. After the pre-crosslinking reaction of the adhesion promoter is finished, the surface of the adhesion promoter still has more active groups, so that the adhesion promoter, the structural adhesive and the metal plate can form more chemical bonds. And the active group of the adhesion promoter can form a firm cross-linking structure with the structural adhesive to firmly connect the structural adhesive and the metal plate.
On the basis of quick wetting, on one hand, the bonding promoter provided by the embodiment of the invention can generate a network structure inside the bonding promoter, so that the bonding strength between the metal plate and the structural adhesive is improved; on the other hand, the surface of the composite material has more active groups, and more chemical bonds can be formed with the structural adhesive and the metal plates on the two sides respectively. Therefore, the adhesion promoter can quickly and firmly bond the metal plate and the structural adhesive together.
In practical applications, the polymerization degree of the silane-based polymer may be 2, 3, 4, 5, 6, 7, 8, 9, 10, or the like. In this case, the polymerization degree of the silane-based polymer is kept low, the molecular weight of the silane-based polymer is kept low, the wetting rate of the adhesion promoter is increased, and the adhesion rate between the metal plate and the structural adhesive is increased.
Specifically, the silane polymer comprises one or more of polydiaminodisilane and polydimethylsiloxane. That is, the silane-based polymer may be a single polydiaminodisilane or polydimethylsiloxane, or a mixture of the polydiaminodisilane and the polydimethylsiloxane. At this time, under the condition of low polymerization degree, polydiaminodisilane and polydimethylsiloxane can form a complete and firm network structure under the crosslinking reactivity, and more active groups can form stable chemical bonds with the metal plate and the structural adhesive.
The cross-linking agent comprises one or more of a tri-functional organosilicon cross-linking agent and a tetra-functional organosilicon cross-linking agent. In this case, the crosslinking agent has a large number of functional groups capable of participating in the crosslinking reaction. When the cross-linking agent and the silane polymer are subjected to cross-linking reaction, a stable three-dimensional network structure can be formed. Moreover, the crosslinking agents facilitate the reaction of the silane-based polymer with the structural adhesive.
In practical applications, the crosslinking agent may be methyltriethoxysilane. At this time, a stable network structure can be formed among the methyltriethoxysilane, the polydiaminodisilane and the polydimethylsiloxane, which is beneficial to improving the cohesive strength of the adhesion promoter.
The catalyst is an organotin catalyst. Organotin catalysts are metal organic compounds formed by direct bonding of tin and carbon elements. Specifically, the organic tin catalyst adopted in the embodiment of the present invention may be one or more of dibutyltin dilaurate, stannous octoate, dibutyltin didodecyl sulfide and dibutyltin diacetate. The reaction speed of the pre-crosslinking reaction can be regulated and controlled by the organic tin catalyst, so that a complete and stable network structure is ensured to be formed, and the adverse effect of the slow reaction of the silane polymer and the crosslinking agent on the strength of the adhesion promoter is avoided.
The adhesion promoter may also include a coupling agent. The coupling agent comprises one or more of amino silane coupling agent and epoxy silane coupling agent. At the moment, the addition of the coupling agent can participate in the pre-crosslinking reaction, increase active groups in the pre-crosslinking reaction process and improve the reaction completion degree of the pre-crosslinking reaction and the stability of a network structure produced by the pre-crosslinking reaction; on the other hand, active groups of the adhesion promoter after the pre-crosslinking reaction can be increased, so that the number of chemical bonds formed between the adhesion promoter and the metal plate and between the adhesion promoter and the structural adhesive can be increased, and the strength of the adhesion promoter for connecting the metal plate and the structural adhesive can be further improved.
In practical application, the aminosilane coupling agent can be selected from gamma-aminopropyltriethoxysilane, gamma-aminopropyltrimethoxysilane, N-beta (aminoethyl) -gamma-aminopropylmethyldimethoxysilane, phenylaminomethyltriethoxysilane, etc.
The adhesion promoter may further include a solvent having a polarity of 5 or less. In this case, the solvent has a low polarity, and is close to the polarity of the paraffin contained in the fingerprint-resistant layer, and can dissolve the paraffin or the like on the surface of the metal plate, thereby improving the wetting effect of the adhesion promoter on the surface of the metal plate and increasing the wetting speed. And after the paraffin and the like on the surface of the metal plate volatilize along with the solvent, the active groups on the surface of the metal plate can be released, so that the number of chemical bonds formed between the metal plate and the adhesion promoter is further increased, and the connection strength between the metal plate and the adhesion promoter is improved.
In practical applications, the solvent may be an alkane compound. At this time, the silane compound has low polarity, not only can well dissolve substances such as paraffin and the like on the surface of the metal plate, but also is easy to volatilize, and is beneficial to reducing substances such as paraffin and the like on the surface of the metal plate by utilizing the volatilization process.
The solvent comprises one or more of diethyl ether and chloroform. The ether and the chloroform can quickly dissolve the paraffin, and the ether is very easy to volatilize at normal temperature, so that the paraffin on the surface of the metal plate can be quickly reduced in the process of coating the adhesion promoter.
The adhesion promoter may include, in mass fraction: 50 to 100 portions of silane polymer, 10 to 20 portions of cross-linking agent, 0.9 to 10 portions of coupling agent, 0.1 to 5 portions of catalyst and 20 to 200 portions of solvent. At this time, the silane polymer, the crosslinking agent, the coupling agent, the catalyst and the solvent in the ratio can be well mixed. More solvents can firstly contact with the metal plate to dissolve substances such as paraffin and the like on the surface of the metal plate and release active groups; then the silane polymer, the cross-linking agent and the catalyst are contacted with the metal plate, and the silane polymer, the cross-linking agent and the catalyst form a chemical bond with active groups on the surface of the metal plate and simultaneously carry out pre-cross-linking reaction inside the metal plate to form a network structure. After the structural adhesive is coated, the active groups on the surface of the adhesion promoter and the structural adhesive form chemical bonds to complete the crosslinking of the adhesion promoter, so that the metal plate and the structural adhesive are easily and firmly bonded under the action of the adhesion promoter.
The embodiment of the invention also provides a preparation method of the adhesion promoter, which is used for preparing the adhesion promoter provided by the embodiment. The preparation method of the adhesion promoter comprises the following steps: uniformly mixing 50-100 parts of silane polymer, 10-20 parts of cross-linking agent, 0.9-10 parts of coupling agent, 0.1-5 parts of catalyst and 20-200 parts of solvent according to a proportion. After the preparation is finished, the adhesion promoter is quickly coated on the metal plate, and then the structural adhesive is coated on the adhesion promoter.
The embodiment of the invention also provides a BIPV system. The BIPV system comprises a metal plate, a structural adhesive and the adhesion promoter. The metal plate and the structural adhesive are bonded together through the adhesion promoter. Specifically, the structural adhesive is mainly silicone structural adhesive.
