Abstract

The invention relates to an environment-friendly adhesive special for compound cleaning foam cotton. The environment-friendly adhesive is prepared from the following raw materials: 16 to 25 parts of ring-opened phenolic oligomers, 40 to 63 parts of formaldehyde, 1.6 to 3 parts of potassium hydroxide, 6 to 15 parts of polyethylene glycol, 8 to 30 parts of silane coupling agent, 4 to 25 parts of silica, 10 to 40 parts of polyvinyl alcohol, 20 to 55 parts of silica sol, and 1 to 4 parts of water-soluble silicone oil emulsion; a preparation method comprises the following steps that firstly, the ring-opened phenolic oligomers and the potassium hydroxide are mixed under a working condition of 70 DEG C, stirred for 5 min, a formaldehyde solution is added and stirred for 20 min, after adding the polyethylene glycol, the silica sol and the water-soluble silicone oil emulsion, a phenolic resin is prepared. Then the silica modified by polyethylene glycol is added into the phenolic resin, and thesilane coupling agent is added to prepare a nano-silica phenolic resin adhesive; the environment-friendly adhesive special for the compound cleaning foam cotton has the advantages of strong adhesive force, energy saving and environmental protection, and high production efficiency.

Description

technical field [0001] The invention belongs to the technical field of production of adhesives for bonding melamine foams, and in particular relates to an environment-friendly adhesive special for composite cleaning foam cotton and a preparation method thereof. Background technique [0002] Melamine foam is a sponge with good sound-absorbing, heat-insulating and cleaning effects prepared by the cross-linking reaction of melamine and formaldehyde solution, and is widely used in sound insulation of high-speed trains and environmental cleaning. Due to its wide range of applications, and because there are more and more types of derivatives made of melamine foam, in recent years, in order to realize the multifunctionality of melamine foam monomers, different melamine resins have been prepared by modifying melamine resins. The melamine foam with different performance is used, and then the melamine foam with different performance is bonded into a single monomer through adhesives to...
