[0124] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to this.

[0125]

[0126] Each component in the following Table 1 was mixed with a mixer in the composition (parts by mass) shown in the table, and the main ingredient shown in the upper row of the table and the curing agent shown in the lower row of the table were prepared.

[0127] Next, 100 g of the prepared main agent and 10 g of the curing agent were mixed to obtain Adhesives 1-2.

[0128] The above-mentioned adhesive 1 is a urethane-based adhesive, and the above-mentioned adhesive 2 is an epoxy-based adhesive.

[0129] [Table 1]

[0130]

[0131] The details of each component in Table 1 are as follows.

[0132] (main ingredient)

[0133] Polymer 1: Urethane prepolymer synthesized below

[0134] 700 g of polyoxypropylene diol (average molecular weight 2000), 300 g of polyoxypropylene triol (average molecular weight 3000), and 499 g of 4,4'-diisocyanate ph...

Embodiment 9～12

[0179] In the flame treatment of Examples 9 to 12 (gas pressure 2.0 MPa), the flame treatment was carried out under the conditions described in Table 2 using a burner with a circular front end and an inner diameter of 6 mm. Specifically, the burner (flame) sweeps the substrate by moving the burner relative to the fixed substrate.

[0180] · Flame treated fuel gas

[0181] As the fuel gas for the flame treatment, LPG (propane, butane mixed) gas was used.

[0182] Here, the speed in Table 2 is the speed of the flame treatment, specifically, the speed [mm / sec] at which the burner is moved relative to the fixed substrate. In addition, the length of the entire flame is the length [mm] from the tip of the burner to the tip of the flame (including the oxidizing flame and the reducing flame). The length of the reducing flame is the length [mm] from the tip of the burner to the tip of the reducing flame (inner flame). The distance is the distance [mm] between the tip of the burner a...

Abstract

The present invention provides a method for manufacturing a laminate member exhibiting exceptional adhesiveness even when no primer is used. The present invention is a method for manufacturing a laminate member, the method involving manufacturing a laminate member that has a crystalline-thermoplastic-resin-containing first member, an adhesive layer, and a second member in the stated order, whereinthe method for manufacturing a laminate member comprises: a surface treatment step for performing a drying treatment on the surface of the crystalline-thermoplastic-resin-containing first member so that condition A is satisfied; an adhesive-agent-imparting step for imparting, without the use of a primer composition, an adhesive agent to the surface of the first member that was subjected to dryingtreatment, and forming an adhesive agent layer on the surface of the first member that was subjected to drying treatment; and an affixing step for affixing the second member to the adhesive agent layer. (Condition A) The drying treatment of the first member is a flame-based treatment, and a reducing flame of a flame in the flame-based treatment is brought into contact with the surface of the first member.

Description

technical field [0001] The present invention relates to a method of manufacturing a laminated structure. Background technique [0002] Conventionally, steel plates have been used for interior and exterior parts of automobiles, such as the body, front doors, rear doors, tailgate, front bumper, rear bumper, and rocker panels. The cases of crystalline thermoplastic resins such as acrylic resins are increasing. [0003] In this way, when resins are used for interior and exterior parts of automobiles, generally, an operation of applying a primer composition to an adhesive surface of a resin member and then applying an adhesive to bond them together is performed. [0004] In addition, for the purpose of providing a method for manufacturing a laminated member that exhibits excellent adhesiveness without using a primer, a method for manufacturing a laminated member has been proposed that sequentially has a first member containing a crystalline thermoplastic resin. 1. A method for ...
