preparation example Construction

[0031] Please refer to figure 1 , the preparation method of sandwich structure composite material comprises the following steps:

[0032] (1) mixing resin with curing agent to prepare matrix resin;

[0033] (2) impregnating glass fiber fabric and / or glass fiber felt with the matrix resin to obtain a FRP preformed layer, placing the FRP preformed layer on both sides of the intermediate layer, pressing and curing to obtain a FRP layer Sandwich structure composites sandwiching foam core layers.

[0034] The realization of above-mentioned step (2) can be A, also can be B, specifically: A, impregnate glass fiber and / or glass fiber felt with described matrix resin, then described glass fiber and / or glass fiber felt are sequentially Pressing and solidifying on the first and second sides of the foam core material, respectively forming a glass fiber reinforced plastic layer on the first and second sides of the foam core material, to obtain a sandwich structure composite material with...

Embodiment 1～2

[0056] Embodiments 1-2 provide a composite material with a sandwich structure and a culture pond assembled with the composite material with a sandwich structure.

[0057] Sandwich structure composite material and its preparation: Example 1-2 The preparation steps of the sandwich structure composite material are the same as the above (1) and (2), wherein step (2) adopts the implementation form described in A. The parameters involved are shown in Table 1 below.

[0058]

[0059]

[0060] Assembling of the breeding pond: The above-mentioned sandwich structure composite materials are used to assemble the pond wall of the breeding pond, and then the bottom of the pond wall is spliced ​​with the thermoplastic resin impermeable film to form a thermoplastic resin impermeable film at the bottom (specifically, a thermoplastic resin woven film ) of a 100-cubic-meter-scale aquaculture pond that can be assembled quickly.

Abstract

A preparing method of a sandwich-structured composite material is provided. The composite material includes a first layer, a middle layer and a second layer which are laminated in order. The first layer and the second layer are fiber-reinforced plastic layers. The middle layer is a foam core material layer. The method includes mixing resin and a curing agent to prepare matrix resin; infiltrating aglass fiber fabric and / or glass fiber felt with the matrix resin to obtain fiber-reinforced plastic preform layers; putting the fiber-reinforced plastic preform layers at two sides of the middle layer; performing lamination and solidification to obtain the composite material in which the foam core material layer is sandwiched with the fiber-reinforced plastic layers. The composite material maintains high rigidity and aging resistance characteristics of fiber-reinforced plastic, also utilizes high shearing strength, good toughness and buffer and heat insulation functions of structured foam, can enhance bonding firmness of the layers, can enhance mechanical properties, and can ensure smoothness of external surfaces of the fiber-reinforced plastic layers so as to obtain a good self-cleaningeffect.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a sandwich structure composite material and its preparation and application. Background technique [0002] In the domestic factory aquaculture aquaculture system, the traditional aquaculture ponds used are mainly divided into three types: concrete aquaculture ponds, polypropylene (PP) aquatic plastic aquaculture ponds and glass fiber reinforced plastic aquaculture ponds. Through comparative analysis, traditional aquaculture ponds have their own shortcomings. Concrete aquaculture pond: the surface is rough, especially the inner surface of the aquaculture pond. Due to the poor compactness of the concrete, the micropores on the inner surface are easy to hide dirt and breed germs. Polypropylene breeding ponds: poor weather resistance, poor thermal insulation performance, and general mechanical strength, so polypropylene breeding ponds can generally only be made less than 80m 2 ...
