Embodiment 1
[0028] See figure 1 , the present invention is a method for preparing epoxy-modified mortar with molding compound as filler, comprising the following steps:
[0029] S1. Pre-adjust epoxy resin, configure 1 part of epoxy resin;
[0030] S2, add 0.25 parts of curing agent to the epoxy resin and stir evenly;
[0031] S3. Add 0 to 1.5 parts of dried cement to the epoxy glue, and stir evenly to form cement;
[0032] S4. Add 4 to 6 parts of molding compound to the epoxy cement, and add 0 to 3 parts of natural sand;
[0033] S5. After stirring with a mixer, form on a vibrating table or use a frequency of 2800--3000 times / min, and an amplitude of 0.75mm to form on a vibrating table;
[0034] S6. The test body is cured in moisture for 24 hours together with the mold, and then removed from the mold in the curing room to the test strength.
[0035] The pre-adjusted epoxy resin in the step S1 described in the above technical solution specifically includes the following steps:
[0036...

Abstract
The invention relates to a preparation method of epoxy modified mortar using a plastic sealing material as a filling material. The method comprises the following steps of S1, presetting epoxy resin and preparing 1 part of epoxy resin; S2, adding 0.25 part of curing agents into the epoxy resin and performing uniform stirring; S3, adding 0 to 1.5 parts of dried cement into the epoxy glue liquid andperforming uniform stirring to form glue paste; S4, adding 4 to 6 parts of plastic sealing materials into the epoxy glue paste and adding 0 to 3 parts of natural sand; S5, after stirring by a stirringmachine, performing shaping on a swing table or performing shaping by using a vibration table with the frequency being 2800 to 3000 times / min and the vibration amplitude being 0.75 mm; S6, performingcuring on a test body and a mold in wet gas for 24 h; then, performing demolding in a curing room to reach the test intensity. The abandoned plastic sealing materials are effectively treated and utilized; the natural sand and stone resources are saved and protected; certain economic benefits are realized.
Description
technical field [0001] The invention relates to the technical field of mortar production, in particular to a method for preparing epoxy-modified mortar with plastic sealing compound as filler. Background technique [0002] Epoxy mortar is based on epoxy resin, together with a series of additives such as accelerators. After mixing and curing, it forms a high-strength, high-cohesion consolidated body, which has excellent impermeability, frost resistance, Salt resistance, alkali resistance, weak acid resistance, anti-corrosion performance and repair and reinforcement performance. Its organic part is the cured product produced by the reaction of epoxy resin and curing agent, which acts as a cementing material in the whole system; the inorganic part is mainly inert fillers, such as quartz sand, cement, etc. In order to optimize performance, diluents, toughening agents, etc. can also be added. This kind of mortar has good workability, high strength, good impact resistance and we...
