Embodiment 1

[0035] The preparation method comprises the following steps:

[0036] (1) Preparation of component A: add the bisphenol A type epoxy resin of component A, active dilution toughening agent, talcum powder and fumed silica into the three-roll machine in sequence, and stir for 8-10 minutes to make it Mix evenly to obtain component A;

[0037] (2) Preparation of component B: add active dilution toughening agent, alicyclic amine curing agent, talcum powder and accelerator 2,4,6-tris(dimethylaminomethyl)phenol of component B to another one in turn In the three-roll machine, stir for 8-10 minutes, and mix well to obtain component B;

[0038] (3) Mixing and preparation: mix the component A prepared in step (1) and the component B prepared in step (2) at a ratio of 1:1 by weight, stir for 5 minutes with a three-roller machine or directly mix and prepare by hand. Two-component bisphenol A type epoxy resin mastic for construction joints.

[0039] After mixing, it can be applied ...

Embodiment 2

[0042] The preparation method is the same as in Example 1.

[0043] In this example, component A and component B are mixed at a ratio of 1:0.8. After mixing, it can also be applied within 40 minutes and completely cured within 25 hours. Main performance parameters: viscous strength: 19MPa, viscosity: 9300mPa·S.

Embodiment 3

[0046] The preparation method is the same as in Example 1.

[0047] In this example, component A and component B are mixed at a ratio of 1:1.2. After mixing, it can be applied within 40 minutes and fully cured within 20 hours. Main performance parameters: viscous strength: 18MPa, viscosity: 9000mpa·S.

[0048] From Examples 1, 2, and 3, it is known that when the A component and the B component are between 1:0.8 to 1.2, they can be well mixed and reacted, and the main performance parameters do not change greatly, which provides great benefits for construction. Convenient, can realize the purpose of the present invention.

Abstract

The invention discloses a bi-component bi-sphenol A-type epoxy resin clay for sealing in the construction, which is formed through mixing and modulating A-component and B-component at the allocated proportion of 1:0.8-1.2 according to the weight. The content of the components of A-component according to weight is as follows: bi-sphenol A-type epoxy resin 80-120, active dilution plasticizer 10-30, talcum powder 160-180; the content of the components of B-component according to weight is as follows: active dilution plasticizer 25-35, alicyclic amine firming agent 40-50, talcum powder 205-215. The preparation method comprises the preparation of both A-component and B-component, and then A-component and B-component are prepared through being agitated by the three roller machine or mixed by the direct manual. The invention has the advantages of low cost and easy operation. The raw materials of the A-component and B-component are put into the three roller machine for agitating for 8-10 min, or by the manual. The working period is long, the solidification is quick, the toughness is high, and the invention allows solidification under the moist environment.

Description

technical field [0001] The invention relates to a two-component bisphenol A type epoxy resin mastic for building joint filling, which is mainly used for repairing cracks in existing buildings and the like. Background technique [0002] With the rapid development of my country's economy, a large number of buildings have sprung up, but there are often cracks in the walls of the buildings. There are many reasons for this situation, such as uneven settlement of the foundation, and uneven wall materials caused by temperature changes. Rules bloated. Traditional caulks are generally added with organic solvents, which pose a potential threat to the human body and the environment, or because the process is too cumbersome, it brings a lot of inconvenience to production and construction. Contents of the invention [0003] The problem to be solved by the present invention is to propose a simple preparation process, economical and environment-friendly two-component bisphenol A type epo...
