Problems solved by technology

The current planting glue products must be used in a dry or slightly humid environment, that is, the water content of the anchored substrate should not be too large, otherwise the durability and strength of the anchor will be affected
[0003] The main disadvantage of the current planting glue products is that they cannot be used in a completely underwater environment. The main reason is that the curing agent used cannot be successfully cured on the surface of the substrate in a completely underwater environment and the bisphenol A ring

Embodiment 1

[0027] Component A: 10 parts of bisphenol A epoxy resin, 1.8 parts of liquid polysulfide rubber, 5 parts of filler, mix and stir evenly. Component B: 4 parts of phenolic modified amine, 13 parts of filler.

Embodiment 2

[0029] Component A: 15 parts of bisphenol A epoxy resin, 2.5 parts of liquid polysulfide rubber, 10 parts of filler, mix and stir evenly. B component: 5 parts of phenolic modified amine, 15 parts of filler.

Embodiment 3

[0031] Component A: 9 parts of bisphenol A epoxy resin, 1.5 parts of liquid polysulfide rubber, 4 parts of filler, mix and stir evenly. Component B: 3 parts of phenolic modified amine, 5 parts of filler.

[0032] The obtained A component and B component are mixed according to the ratio of A:B mass ratio of 1:1 to obtain the rebar glue.

[0033] The usage method of the present invention:

[0034] When using it, mix it well according to the ratio of A:B=1:1 to get the rebar glue, then squeeze the obtained rebar glue into the hole to be anchored to achieve a predictable amount, and then rotate the rebar to be anchored into the hole , After the completion, it is forbidden to move the steel bars again, and wait for the glue to cure.

[0035] The performance test data of the prepared bar-planting glue of the present invention are shown in Table 1.

Abstract

The invention discloses modified bisphenol-A epoxy resin inserted bar glue in the complete underwater environment and a preparation method. The inserted bar glue comprises the following ingredients by weight ratio: ingredients A: 10-15 parts of bisphenol-A epoxy resin, 1.5-2.5 parts of a rubber toughening agent and 5-10 parts of a spherical filler with the degree of sphericity being 0.8-1; ingredients B: 3-5 parts of a modified base amines curing agent and 5-15 parts of a spherical filler with the degree of sphericity being 0.8-1. The ingredients A and the ingredients B are mixed for construction according to the ratio of 1:1. According to the inserted bar glue and the preparation method, steel bars can be inserted and screw rods can be embedded on the surfaces of substrates completely underwater; the inserted bar glue can be cured at ordinary temperature in the complete underwater environment, and the steel-steel shearing strength can reach to over 23 MPa after curing.

Description

technical field [0001] The invention relates to a planting glue and a preparation method thereof, in particular to a modified bisphenol A epoxy resin planting glue suitable for a completely underwater environment and a preparation method thereof. Background technique [0002] At present, planting glue is widely used in the field of construction for post-anchoring of screws and steel bars. Ordinary planting glue is composed of two components. Component A is mainly a mixture of bisphenol A epoxy resin and inorganic filler, and component B is mainly a curing agent and inorganic filler. When using it, components A and B must be fully stirred and mixed according to the specified ratio to cause a chemical reaction to occur. solidify. So as to achieve the purpose of anchoring screw rods and steel bars. The current planting glue products must be used in a dry or slightly humid environment, that is, the water content of the anchored substrate should not be too large, otherwise the...
