Description
Technical Field
The invention belongs to the field of protective materials, and particularly relates to an efficient protective composite board and a preparation method thereof, and also relates to application and an application method of the efficient protective composite board.
Background
Thermosetting powder coating refers to a solvent-free 100% solids powder coating. Thermosetting powder coatings are generally composed of thermosetting resins, curing agents, pigments, fillers, auxiliaries and the like, and are widely applied to the fields of buildings, woodware, automobiles, household appliances and the like as substrate protective coatings due to the characteristics of no solvent, no pollution, recoverability, environmental protection, energy and resource saving, labor intensity reduction, high mechanical strength of coatings and the like.
Since thermosetting powder coating is powder in nature, it is always considered to be applied only to coating protective materials for various hard substrates such as metal, wood, glass, etc. The inventor's Chinese invention patents associated with prior application numbers CN201610685536.0 and CN201610685240.9 respectively disclose a packaging material for a photovoltaic module and a preparation method thereof, and propose that a composite material obtained by compounding fiber cloth with super-weather-resistant polyester powder paint or super-weather-resistant polyester powder paint is used as the packaging material of the photovoltaic module to replace a traditional toughened glass layer or a back plate layer to solve the problems of light weight and convenient installation of the photovoltaic packaging material, thereby obtaining a surprising technical effect, which is a technical breakthrough in the photovoltaic packaging industry.
With the continuous popularization, application and implementation of the applicant and a large amount of experimental research, the inventor finds that the composite materials with more excellent performance and technical effect can be obtained by compounding different types of thermosetting powder coatings and fiber cloth under specific conditions, and the composite materials can be applied to wider fields, so that the light weight and flexibility of related products are realized, and the products are endowed with higher quality.
Disclosure of Invention
In view of the above, the invention aims to provide an efficient protective composite board, and a preparation method, an application and an application method thereof, on the premise of exerting the inherent advantages of the thermosetting powder coating, the efficient protective composite board has excellent ultraviolet resistance, ageing resistance, impact resistance, flexibility and other properties, fire resistance and other properties, is stable in storage performance, convenient to store and transport, low in manufacturing cost, light in weight, flexible, attractive in appearance, light-transmitting and decorative, and is very suitable for being used as a photovoltaic packaging material, a building material and an automobile exterior trim material.
It should be noted that: the invention relates to Chinese patent with prior application numbers of CN201610685536.0 and CN201610685240.9, and provides a composite material obtained by thermally bonding super-weather-resistant polyester powder coating or super-weather-resistant polyester powder coating on fiber cloth, wherein the composite material is simultaneously crosslinked and cured in the lamination process of a photovoltaic module, this is because one skilled in the art would recognize this as the best process path based on common general knowledge and routine experience, because the heating environment of lamination is also suitable for the cross-linking and curing conditions of the powder coating, and the two are simultaneously carried out, the bonding of the composite thermosetting layer structure with other layer structures can be facilitated, therefore, in the process path, even when technical problems such as differences in the properties of thermosetting materials and thermoplastic materials commonly used for encapsulating materials are encountered, a stepwise heating and pressure cooling step is used in an effort to solve the technical problems.
However, in practical applications, the applicant finds that the composite material has poor storage stability and is inconvenient for long-term transportation due to the thermal bonding composite process, so that long-distance transportation cannot be generally specified, packaging cannot be produced nearby, and the storage period cannot generally exceed 3 months, which undoubtedly increases the manufacturing cost; moreover, the super-weatherable polyester powder coating usually generates bubbles and/or gas during crosslinking and curing, and the bubbles and gas generated during the lamination process of the photovoltaic module directly influence the flatness and the lamination quality of the photovoltaic module, so that the applicant hopes to perform research and experiment again on the basis of the innovative composite materials, and finally surprises that the technical scheme of the invention is obtained.
