Abstract

The invention provides a preparation method of single component room temperature curing epoxy construction glue and belongs to the technical field of construction adhesive preparation. Epoxy resin and diluent are added in a reactor first and mixed evenly, then curing agent, accelerant, coupling agent and filler are sequentially added to be mixed, meanwhile, mixing time is controlled, and finally vacuum defoamation, discharge and canning are carried out to form the single component room temperature curing epoxy construction glue. The proportion of weight parts of the epoxy resin, the diluent, the curing agent, the accelerant, the coupling agent and the filler is as follows: 80-100 parts of the epoxy resin, 5-25 parts of the diluent, 10-20 parts of the curing agent, 3.0-5.0 parts of the coupling agent, 0.5-2.0 parts of the accelerant, and 1.0-8.0 parts of the filler. The preparation method of the single component room temperature curing epoxy construction glue has the advantages that raw materials are rich in source and low in price; formula is reasonable and process is simple, complicated devices and complicated operation are not needed; and produced products are convenient to construct, and waste can be avoided.

Description

technical field [0001] The invention belongs to the technical field of preparation of construction adhesives, and in particular relates to a preparation method of single-component room temperature curing epoxy construction adhesive. Background technique [0002] With the rapid development of my country's construction industry, new building materials are also being continuously developed and applied. In order to meet the bonding requirements of most building materials such as stone, wood, concrete, metal, ceramics and glass, the adhesive with epoxy resin as the main body is used. Widely used in construction field. [0003] At present, most of the epoxy adhesives commonly used in the construction industry are two-component, and its main components include: A component is composed of epoxy resin and filler; B component is composed of epoxy curing agent and filler. Ready to use. Two-component epoxy construction adhesive disclosed in Chinese Patent Application Publication No. CN...
