Problems solved by technology

The disadvantages are that the reaction speed is too fast, the water resistance is poor, the brittleness is high, the temperature resistance is low (<70 ℃), the storage period is short, and the durability is not good, so the corresponding additives should be added when compounding the glue, and it is mostly used for temporary use. sexual bonding
The disadvantage is that the smell is not good

Abstract

The invention discloses an instant adhesive. The instant adhesive is prepared from the following raw materials: polymethyl methacrylate, ethyl cyanoacetate, 30-35% formaldehyde, piperidine, dichloroethane, a hydroquinone polymerization inhibitor and modified sepiolite. The instant adhesive is prepared by the following steps of: based on parts by weight, mixing the polymethyl methacrylate, the piperidine, the ethyl cyanoacetate and the 35% formaldehyde and then adding the obtained mixture into a reaction kettle to react for 1 hour at 70 DEG C when heated; and then adding the hydroquinone polymerization inhibitor, the modified sepiolite and the dichloroethane for reduced pressure distillation at 180 DEG C. The instant adhesive disclosed by the invention is an adhesive which has single component and is instantly cured on meeting moisture, and is convenient to use, the adhered surface needs no special pretreatment, heating and pressurizing are not necessary, and the adhesive is widely applied to the adhesion and location between plastics, and between the plastic and metal, is water-fast, cannot be combusted, is good in low-temperature adhesion property, and is low in cost.

Description

technical field [0001] The invention mainly relates to an instant adhesive and belongs to the field of materials. Background technique [0002] As the name implies, instant adhesive is glue that can be used immediately and quickly. It is mainly based on α-ethyl cyanoacrylate, adding tackifiers, thickeners, stabilizers, tougheners, and polymerization inhibitors. Through advanced production A one-component fast-curing adhesive synthesized by technology; it is a high-strength, fast adhesive that can be used for high-speed bonding of various types of materials, especially suitable for use in the wood industry; for tight fit, porous materials, such as rubber , metal, plastic, wood, etc. can achieve the strongest bonding effect; this glue is a single component, no solvent, no need to add catalyst, heat or pressure adhesive, only need a thin layer of glue, it can be used Atmospheric humidity in the air produces a high degree of polymerization to achieve the best bonding effect...
