Problems solved by technology

[0005] Its shortcoming is that the epoxy resin cement used for filling cracks is used to prevent it from flowing out from the cracks when it is filled into the cracks. Its viscosity is large and its fluidity is poor. The inner surface of the crack where the epoxy resin mortar is insufficiently filled still cannot be filled, and there are still gaps; and this type of gap will lead to a decrease in the bonding stability between the cured epoxy resin mortar and the inner surface of the crack, and the inner surface of the original crack will be damaged. It expands or shrinks with temperature and deforms when it receives external pressure, so that the gap expands or connects to form a gap connected to the outside world. Water and air can enter the gap to further expand the gap and form new cracks, reducing the filling of epoxy resin cement. Effective time of the effect

Embodiment A1

[0051] Preparation of S1 composition A: add 100 parts of bisphenol A epoxy resin and 16 parts of microsilica powder (1250 mesh) into a mixer according to the ratio of parts by mass, and stir for 10-12 minutes, and stir evenly to obtain composition A;

[0052] S2 Preparation of composition B: mix 100 parts of ketimine and 8 parts of gel generating agent (NaOH) according to the mass parts and add them into another mixer and stir for 10-12 minutes, and stir evenly to obtain composition B;

[0053] S3 Mixing configuration: The ratio of composition A and composition B is measured as 1:1 by weight, and composition A and composition B are added to the mixer at a stirring speed of 100r / min, and the epoxy resin polymer cement is obtained after stirring for 4-5 minutes .

[0054] Wherein the proportion of composition A and composition B is 1:0.8-1.2 by weight, which is convenient for actual preparation and use on the spot, and reduces calculation, and this is selected as 1:1.

Embodiment A2

[0056] Preparation of S1 composition A: add 100 parts of bisphenol A epoxy resin and 16 parts of microsilica powder (1250 mesh) into a mixer according to the ratio of parts by mass, and stir for 10-12 minutes, and stir evenly to obtain composition A;

[0057] S2 Preparation of composition B: mix 100 parts of ketimine and 8 parts of gel generating agent (select KOH) according to the mass parts and add them into another mixer and stir for 10-12 minutes, and stir evenly to obtain composition B;

[0058] S3 Mixing configuration: The ratio of composition A and composition B is measured as 1:1 by weight, and composition A and composition B are added to the mixer at a stirring speed of 100r / min, and the epoxy resin polymer cement is obtained after stirring for 4-5 minutes .

Embodiment A3

[0060] Preparation of S1 composition A: add 100 parts of bisphenol A epoxy resin and 16 parts of microsilica powder (1250 mesh) into a mixer according to the ratio of parts by mass, and stir for 10-12 minutes, and stir evenly to obtain composition A;

[0061] S2 Preparation of composition B: mix 100 parts of ketimine, 4 parts of NaOH, and 4 parts of KOH according to the mass parts and add them into another mixer and stir for 10-12 minutes, and stir evenly to obtain composition B;

[0062] S3 Mixing configuration: The ratio of composition A and composition B is measured as 1:1 by weight, and composition A and composition B are added to the mixer at a stirring speed of 100r / min, and the epoxy resin polymer cement is obtained after stirring for 4-5 minutes .

Abstract

The invention discloses an epoxy resin polymer daub, and a preparation method thereof. The epoxy resin polymer daub is prepared from a component A and a component B via blending at a weight ratio of 1:0.8-1.2; the component A comprises, by mass, 100 parts of bisphenol A type epoxy resin, and 16 to 22 parts of silica micropowder; the component B comprises, by mass, 100 parts of a curing agent, and8 to 11 parts of a gel generating agent; the curing agent is a polyamine type alkaline curing agent, and the gel generating agent is KOH and / or NaOH. When the epoxy resin polymer daub is introduced into wall cracks, expansion of the epoxy resin polymer daub is realized, the surface of the epoxy resin polymer daub is combined with building crack internal side surfaces firmly, generation of gaps isavoided, and the service life is prolonged after filling of the cracks.

Description

technical field [0001] The invention relates to construction gap filling cement, in particular to epoxy resin polymer cement and a preparation method thereof. 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 irregularities in the wall materials caused by temperature changes. swell. [0003] Existing solutions use cement to fill up the cracks, and then the crack openings are ground or leveled with cement or other coatings to fill up the cracks. For example, the Chinese invention with the notification number CN101205129B "two-component bisphenol A epoxy resin cement and preparation method thereof for building joints" discloses a two-component bisphenol A epoxy resin cement, which is Component and B component are mixed and prepared, the mixing ratio is 1:...
