Problems solved by technology

Therefore, people began to use acrylic glue with good adhesion to FRP for bonding and closing, but the hull is generally ten meters or even longer, and the closure of the hull must be coated at one time, and then closed and bonded. Therefore, acrylic adhesives are required to have a long operating time (greater than 90 minutes)
However, because the mixed colloid is exposed to the air for too long, it will cause a large amount of volatilization of the main components, which will affect the bonding strength and directly lead to the reduction of seawater salt spray resistance.
The above problems directly limit the application of acrylic glue in the yacht industry

Embodiment 1

[0030] Table 1:

[0031]

[0032] In this embodiment, the sealing agent is composed of 40% acrylate-modified butadiene resin with a melting point between 47°C and 64°C and 60% polyvinyl alcohol with a melting point between 47°C and 64°C.

[0033] In this example, the oxidizing agent component and the reducing agent component were prepared at a volume ratio of 1:10 to prepare an acrylate adhesive.

[0034] 1. Preparation method:

[0035] (1) Oxidant component: add the acrylate monomer methyl methacrylate into the reaction kettle, add the elastomer MBS and stir until the elastomer is completely dissolved; then add epoxy resin and stabilizer oxalic acid and stir until evenly mixed; Finally, the initiator benzoyl peroxide is added and stirred until the mixture is uniform, and the preparation is completed after vacuuming.

[0036] (2) Reductant component: add acrylate monomer methyl methacrylate and methacrylic acid into the reaction kettle, add elastomer neoprene and...

Embodiment 2

[0045]

[0046] In this embodiment, the blocking agent is the same as in Embodiment 1.

[0047] The preparation method and performance test of this example are the same as those of Example 1; in this example, the acrylate adhesive is prepared with a volume ratio of the oxidizing agent component and the reducing agent component being 1:10.

Embodiment 3

[0049] table 3:

[0050]

[0051] In this embodiment, the sealing agent is composed of 60% acrylate-modified butadiene resin with a melting point between 47°C and 64°C and 40% polyvinyl alcohol with a melting point between 47°C and 64°C.

[0052] The preparation method and performance test of this example are the same as those of Example 1; in this example, the acrylate adhesive is prepared with a volume ratio of the oxidizing agent component and the reducing agent component being 1:10.

Abstract

The invention relates to an acrylate adhesive which is a double component adhesive. The acrylate adhesive comprises an oxidizing agent and a reducing agent, wherein the oxidizing agent is prepared from the following components in percentage by weight: 25-60% of an acrylate monomer containing at least one vinyl, 5-50% of an elastomer, 0.5-20% of an initiator, 0.1-5% of a stabilizer and 0-30% of epoxy resin; the reducing agent is prepared from the following components in percentage by weight: 25-60% of an acrylate monomer containing at least one vinyl, 0-25% of methacrylic acid, 0-50% of an elastomer, 1-10% of an accelerant, 0.1-5% of a stabilizing agent, 0.01-2% of organic salt of transition metal, 0-30% of epoxy resin and 1-10% of a sealing agent, wherein the volume ratio of the components of the oxidizing agent and the reducing agent is 1:10. The adhesive provided by the invention has the advantages that volatilization of main compositions can be reduced under the condition of guaranteeing relatively long operating time, and reduction of shear strength is effectively prevented after aging by salt mist, so that the sea water salt mist resistance of a yacht is improved.

Description

technical field [0001] The invention relates to the technical field of two-component acrylic adhesives, in particular to an acrylic adhesive used in the yacht industry. Background technique [0002] With the development of material science, more and more new polymer materials have been widely used in various fields. For the yacht industry, tall and thick steel plates are becoming more and more inappropriate, and novel fiberglass keels and hulls have emerged as the times require. However, the closure of the FRP hull has become a difficult problem, and the traditional locking and sealing method has not achieved good results. Therefore, people began to use acrylic glue with good adhesion to FRP for bonding and closing, but the hull is generally ten meters or even longer, and the closure of the hull must be coated at one time, and then closed and bonded. Therefore, it is necessary for the acrylate glue to have a long working time (greater than 90 minutes). However, because th...
