Abstract

The invention relates to a high-strength construction glue and a preparing method thereof. According to the high-strength construction glue, polyvinyl alcohol, epoxy resin, hydroxyl cellulose, polyacrylamide, polyamide, ethylene vinyl acetate emulsion, polyoxyethylene ether, potassium persulfate, carbon fiber particles, a surfactant and a silane coupling agent are adopted as raw materials, suitable weight matching is conducted, the raw materials are reacted under specific conditions, and the high-strength construction glue is generated; the high-strength construction glue is high in adhesive force, and has the advantages of being high in pressure strength and tensile strength, short in film forming time and curing time, convenient to use and high in construction efficiency. Data displays that the peel strength of the high-strength construction glue reaches 15 Mpa or above, and the tensile shear strength reaches 21 Mpa or above.

Description

Technical field [0001] The invention belongs to the technical field of construction glue, and specifically relates to a high-strength construction glue and a preparation method thereof. Background technique [0002] Construction glue is widely used in construction engineering and is an indispensable material in construction engineering. Construction glue is used in every process of the construction industry, and even every material. Building sealants are mainly used to seal various joints or holes in buildings to prevent the penetration of gas, liquid, and solids, and prevent structural materials from being damaged when the structure is displaced, so as to achieve heat preservation, sound insulation, waterproof, dustproof, The function of gas prevention, fire prevention, corrosion prevention, shock absorption and prevention of foreign matter accumulation in the joints. However, the performance of the existing construction glue cannot meet the requirements of use, the permeabili...
