Problems solved by technology

However, in the subsequent production practice, it was found that when the ribs were bonded to the panel, and the edge of the panel was welded and sealed, when the sparks splashed onto the bonding surface, the adhesive layer would burn, which required manual extinguishing before continuing. Production has caused a certain waste of manpower and material resources, and has also produced certain quality hidden dangers
Another example is the bonding of load-bearing parts of construction machinery and large steel structures. When the flame burns the glue layer, if the glue layer is burned, it will cause the load-bearing parts to debond and cause serious property losses.

Abstract

The invention discloses a flame retardant acrylate adhesive, belongs to the technical field of two-component acrylate adhesives, and mainly solves the problem that after curing acrylate adhesives in the prior art may cause adhesive layer combustion when the acrylate adhesives meet spark sputtering. The flame retardant acrylate adhesive is mainly characterized by including a main agent component which comprises 25 to 60 parts of acrylate monomers containing at least one vinyl, 1 to 25 parts of methacrylic acid, 0 to 25 parts of an elastomer, 1 to 25 parts of a fire retardant, 0.5 to 8 parts of an initiator and 0.1 to 5 parts of a stabilizer; and a curing agent component which comprises 25 to 60 parts of the acrylic monomers containing at least 1 vinyl, 1 to 25 parts of the methacrylic acid, 0 to 25 parts of the elastomer, 1 to 25 parts of the fire retardant and 1-10 parts of an accelerant. The flame retardant acrylate adhesive has an improved flashing point, is nonflammable, can achieve the effects of being non-ignitable when meeting a fire or self-extinguishing when being away from the fire, and is mainly used as a flame retardant acrylate adhesive.

Description

technical field [0001] The invention belongs to the technical field of two-component acrylate adhesives, in particular to a flame-retardant acrylate adhesive. Background technique [0002] Acrylic structural adhesives have remarkable characteristics such as fast curing at room temperature, high strength, good toughness, oily surface bonding, strong adaptability, and simple process. Therefore, it is widely used in the structural bonding of aerospace, aviation, automobile, machinery, ships, electronics, electrical appliances, instruments, construction, furniture, toys, railway vehicles, civil engineering, arts and crafts and other industries. [0003] With the continuous expansion of application fields, acrylic adhesives have achieved industrial applications in many fields by virtue of their excellent properties. For example, in the manufacturing process of a large container, since its panel area is large and easy to bend, it is necessary to use reinforcing ribs to fix it. T...
