Abstract

The invention relates to the technical field of adhesives, and discloses a water-resistant high-strength inorganic silicate adhesive and a preparation method thereof. The adhesive comprises the following components in parts by weight: 30-40 parts of sodium silicate, 20-30 parts of modified mica powder, 20-25 parts of a quartz powder curing agent, 5-10 parts of composite potassium hexatitanate whiskers, 1-3 parts of a sodium carboxymethyl cellulose stabilizer, 30-40 parts of absolute ethyl alcohol and 25-35 parts of water. The preparation method comprises the following steps: adding the sodiumsilicate, the composite potassium hexatitanate whiskers and the sodium carboxymethyl cellulose stabilizer into the water, and carrying out uniform mixing to obtain a component A; adding the modified mica powder and the quartz powder curing agent into the absolute ethyl alcohol, and carrying out uniform stirring and mixing to obtain a component B; and uniformly mixing and stirring the component A and the component B to obtain the water-resistant high-strength inorganic silicate adhesive. The silicate adhesive prepared by the preparation method disclosed by the invention has relatively high bonding strength and water resistance.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a water-resistant high-strength inorganic silicate adhesive and a preparation method thereof. Background technique [0002] Inorganic adhesives are an ancient and young material. Human ancestors began to use inorganic adhesives thousands of years ago. According to textual research, they have been used in the manufacture of large-scale painted copper chariots and horses of the Qin Dynasty unearthed in the Museum of Terracotta Warriors. Inorganic adhesive. However, the formal research on inorganic adhesives began in the last century. In the 1970s, due to the application needs of electronics and high-precision machinery, Japan developed many patented products of inorganic adhesives. It was only in the late 1980s that my country began to research and start. late. With the rapid development of aviation and aerospace technology, there is an urgent need for new non-metallic materials...
