Description
Technical Field
The invention belongs to the field of adhesives, and particularly relates to a solvent type nail-free adhesive as well as a preparation method and application thereof.
Background
The nail-free glue is also called a liquid nail, is a multifunctional decorative adhesive with strong adhesive force, and can replace a nail to realize non-nail hole bonding. The nail-free glue has the characteristics of high curing speed, high bonding strength, wide application range, convenience in use and the like, and is widely applied to industries of decoration, furniture manufacture, artware manufacture and the like. Non-flammable liquid means that the product has a flash point in the closed cup test of over 60 deg.C, or a flash point in the open cup test of over 65.6 deg.C, or a flash point of over 35 deg.C and does not burn continuously. The traditional solvent type nail-free glue is prepared by dissolving thermoplastic rubber, tackifying resin and the like by a solvent A, and due to the use of the solvent A, a product is a highly flammable liquid and is classified according to related regulations, the traditional nail-free glue is dangerous goods, and transportation management and control are required according to dangerous goods during transportation. With the increasing importance of the country on safety production, the disadvantages of the traditional nail-free glue in the aspects of transportation, storage and the like are gradually highlighted.
Conventional solvent-based nail-free adhesives are classified as dangerous goods and are limited in transportation and storage. In order to solve the problem, most manufacturers replace the traditional solvent type nail-free glue with MS nail-free glue or develop water-based nail-free glue. However, the MS nail-free glue is expensive, so that the application of the MS nail-free glue is limited; the water-based nail-free glue product requires at least one base material as an absorption surface, and has strict requirements on the base material.
The traditional solvent type nail-free glue is environment-friendly, has high cost performance and still has a wide market, but most of the solvent type nail-free glue on the market is dangerous goods, and the application of the solvent type nail-free glue is limited because the solvent type nail-free glue needs to be stored and transported in a specific mode. In other words, there is a great need in the market for a non-flammable solvent-based nail-free adhesive.
