Abstract

The invention discloses a strong adhesive. According to the invention, a high-molecular synthesized latex with high adhesion, a special hydraulic coagulant powder and a plurality of auxiliary agents are prepared according to a scientific and reasonable formula, such that strong adhesive is obtained. The strong adhesive is advantaged in simple construction technology, high adhesive performance with media such as cement mortar, concrete, stones, and ceramic materials, fast adhesion and solidification, small linear shrinkage, fire retardance, and no sagging when applied vertically. When the strong adhesive is contacted for a long time, the skin of a construction worker is not harmed. The strong adhesive provides substantial effects in reducing the shipped weight of ship materials, improving construction performances, and protecting the health of construction workers. The strong adhesive is suitable to be used in pavements of ceramic decorative materials in damp cabins such as kitchens, catering rooms and toilets in ship superstructures. The strong adhesive is also suitable for civil buildings.
