However, the research and development of new binders with special functions and uses suitable for various new materials is obviously lagging behind.
Traditional binders are often suitable for a single material, but for new composite materials and different types of materials, the bonding effect is poor, the strength is low, and the toughness is poor, which seriously restricts the use of new composite materials

Abstract
The invention relates to a preparation method for a strong-strength adhesive composition. The adhesive composition comprises specific modified nanometer silica powder and modified nanometer titania powder, and by the surface-modified nanometer powder, the strength and the toughness of an adhesive layer can be effectively improved. In addition, the adhesive composition further comprises potassium titanate whiskers and silicon carbide whiskers, and by the combination of the potassium titanate whiskers and silicon carbide whiskers, the hardness, the strength and the wear resistance of the adhesive layer can be effectively improved. With the addition of diethylenetriamine, nitrilotriacetic acid and 5 parts of 2-acrylamido-2-methylpropanesulfonic acid, a layer of thin film is formed on the surface of the adhesive composition, so that the crease resistance, the dimensional stability and the deformation resistance of the adhesive composition are enhanced, meanwhile the effect of sealing formaldehyde is achieved, and the formaldehyde release is remarkably reduced. The adhesive composition is convenient to construct, and the adhesive layers formed on the surfaces of wood, a density board, metal, glass and ceramics have excellent performance.
Description
technical field [0001] The invention relates to a preparation method of a high-strength adhesive composition. Background technique [0002] With the rapid development of my country's material field, a large number of new composite materials with excellent properties are widely used in infrastructure such as buildings, railways, and highways, aerospace, medical, home appliances, and other fields. However, the research and development of new binders with special functions and uses suitable for various new materials is obviously lagging behind. Traditional adhesives are often suitable for a single material, but have poor bonding effects, low strength, and poor toughness for new composite materials and different types of materials, which seriously restrict the use of new composite materials. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and a kind of preparation method of high-strength adhesive composi...
