Problems solved by technology

Therefore, the disadvantages brought by this technique include: (1) higher reagent cost: an appropriate solvent must be used to dilute the main agent, otherwise the high solid content in the main agent will cause the main agent and curing agent to mix evenly (2) The operation steps are cumbersome: the existing process not only includes the step of diluting the main agent with a solvent, but also includes the step of stirring and mixing the main agent and curing agent after dilution; (3) Equipment cost High: It is precisely because of the existence of solvents that it is necessary to set up drying equipment so that the mixed glue containing solvents can be volatilized to a predetermined content through a long-path (2-5m) drying channel to ensure the later bonding strength. This will prolong the process time and increase the cost of equipment; (4) The use of organic solvents is large, which brings more negative impacts on the environment and people, and also brings harmful residues to composite materials, limiting the application of materials

Embodiment 1

[0049] In this embodiment, the method of the present invention is described by taking a solar battery backsheet prepared by compounding two-component adhesives as an example. In this embodiment, a solar battery backsheet laminated with PDVF+PET+PE is used as an example to illustrate. In other embodiments, the method and system of this embodiment can be used to make PDVF+PET+PDVF backboard, PVF+PET+PE backboard, PVF+PET+PVF backboard, PDVF+PET+P VF backboard, etc. .

[0050] Such as figure 1 As shown, the PET film material 21 is stretched straight through the tension shaft after unwinding and bypassed from the support roller A, where a hot melt adhesive coating device 22 is provided, and the hot melt adhesive coating device 22 is connected to the support roller A. A is close, and the hot-melt adhesive coating device 22 is connected to a hot-melt adhesive machine through a rubber delivery pipe, and the hot-melt resin heated in the hot-melt adhesive machine into a fluid state is...

Embodiment 2

[0073] The difference between this embodiment and Embodiment 1 is that a non-hot-melt two-component adhesive is used. Wherein the surface of the PET film 21 is coated with component A, and the surface of the PE film 23 is coated with component B. Component A does not need to be connected to a hot-melt adhesive machine. Since the coated components A and B are in a fluid state at room temperature, they can be directly coated, and then laminated by laminating rollers 25 to obtain intermediate film materials. Other operations are the same as in Example 1, except that the two-component adhesive used in this example is a cold glue type adhesive.

[0074] The composition of component A is in parts by mass: 180-220 parts of methyl methacrylate (industrial), 30 parts of hydroxyethyl methacrylate (industrial), 35-50 parts of ABS (solid, industrial), cumene peroxidation Hydrogen (industrial) 15 parts, methacrylate reinforcing agent 15 parts.

[0075] The composition of part B is in par...

Abstract

The present invention relates to a method for manufacturing a composite material based on a two-component adhesive, the two-component adhesive comprising a main agent and a curing agent, the main agent being fluidically applied to a surface to be bonded of a first material, the curing agent being fluidically applied to a surface to be bonded of a second material; and the to-be-bonded surfaces of the first material and the second material being oppositely pressed to obtain the composite material. The invention also comprises a two-component adhesive-based composite material manufacturing systemcorresponding to the method. The main agent and the curing agent in the double-component adhesive are respectively applied to two surfaces to be bonded of a piece to be bonded, and then the compositematerial is obtained by pressing and bonding. As the main agent and the curing agent are already applied on the two surfaces to be bonded, the main agent and the curing agent are respectively thinnedby spreading, and an approximate 'dilution and dispersion' effect is achieved, highly uniform contact and mixing between the two components which are the main agent and the curing agent are facilitated, and solvent dilution, stirring and other homogenization treatment, solvent drying and the like are not needed.

Description

technical field [0001] The invention relates to a method for manufacturing a composite material, in particular to a method for manufacturing a composite material based on a two-component adhesive. Background technique [0002] The two-component adhesive refers to the adhesive that can only play the role of bonding after the two components are mixed according to a certain ratio. Adhesive that does not cure naturally when separated. The common ones are epoxy resin AB glue, acrylic resin AB glue and so on. Curing agent is also called hardening agent, curing agent or stabilizer, which is a kind of substance or mixture that promotes or controls the curing reaction. Resin curing is through chemical reactions such as condensation, ring closure, addition or catalysis, so that the thermosetting resin undergoes an irreversible change process, and curing is completed by adding a curing (crosslinking) agent. Different types of resins choose different curing agents, and the same type ...
