Embodiment 1

[0025] Embodiment 1: present embodiment table 1, table 2 have shown that adopt low-carbon fatty amine stabilizer of the present invention to obtain better storage stability: sample A adopts low-carbon fatty amine stabilizer of the present invention, and sample B is Set times and tensile shear strengths of controls without the stabilizer of the present invention were measured after curing of Sample A and Control B with the second component in Table 1. The 70°C storage stability test of the control sample B does not exceed 30h, while the 70°C storage stability test of the sample A reaches 120h, the basic physical properties are not significantly different from the control sample B, and the shear strength after aging does not decrease , proving that the stable system of the present invention has excellent storage stability.

Embodiment 2

[0030] Embodiment 2: present embodiment table 3, table 4 have shown to adopt low-carbon aliphatic amine of the present invention and metal chelating agent stabilizer to obtain better storage stability: sample C is to adopt stabilizer of the present invention, and sample B is Set time and tensile shear strength of the control without the stabilizer of the present invention were measured after curing of Sample C and Control B with the second component in Table 1. The 70°C storage stability test of sample C reached 360h, and the basic physical properties were not significantly different from those of control sample B, and the shear strength after aging did not decrease, which proved that the stable system of the present invention had excellent storage stability.

Abstract

The invention discloses an acrylate adhesive with stabilizer and a preparation method thereof. The stabilizer is added into the components of dual main-agent acrylate adhesive that comprises peroxideto ensure that storage stability of the component of the dual main-agent acrylate adhesive is good and the performances of the component of the dual main-agent acrylate adhesive such as shear strength,shock strength, positioning time, etc. are remained unchanged. The stabilizer of the acrylate adhesive is low-carbon aliphatic amine or comprises low-carbon aliphatic and metal chelating agent. Thelo w-carbon aliphatic amine can postpone the polymerization of monomer, thus enhancing the storage stability of the acrylate adhesive. The low-carbon aliphatic amine is that alkyl, dialkyl or trialkylsubstitutes the amine with the alkyl chain length from C2-C8, while the metal chelating agent is ethylene diamine tetraacetic acid (EDTA) and the salts thereof. The acrylate adhesive of the inventionhas good storage stability which can reach 360 h under 70 DEG C, without reducing the performances of shear strength, shock strength and positioning time, etc.

Description

technical field [0001] The invention relates to the technical field of acrylate adhesives, in particular to a stabilizer for acrylate adhesives and a preparation method thereof. Background technique [0002] The second generation acrylate adhesive is composed of methacrylate monomers or prepolymers, elastomers, initiators, accelerators, stabilizers, etc., monomers, elastomers, initiators, stabilizers constitute a component, monomers , elastomers, accelerators, etc. are another component. According to the method used, SGA is divided into two types: primer type and double main dosage type. [0003] The dual main dosage form SGA is also called mixed type and AB type. The elastomer is dissolved in the reactive acrylate monomer, and stabilizers, initiators, etc. are added to form the A agent (called the first component in the present invention). The elastomer is dissolved in the reactive acrylate monomer, and accelerators, plasticizers, etc. are added to form agent B (referred...
