example 1

[0025]Weigh 16g of diatomite, grind it for 8 minutes, pass it through a 120-mesh sieve, collect the sieved diatomite powder, mix and stir the sieved diatomite powder and silane coupling agent KH-570 for 5 minutes according to the mass ratio of 5:1 to obtain a mixture , put the mixture into a fermenter with 5% sucrose by weight of the mixture and yogurt with 0.4% by weight of the mixture, and seal and ferment for 7 days at a temperature of 35°C. After the fermentation is over, take out the fermentation product, which is the modified Diatomaceous earth powder; mix ammonium polyphosphate, melamine and pentaerythritol in a mass ratio of 2:1:1 and stir for 3 minutes to obtain a mixture, then add 3% polyethylene glycol by mass of the mixture and deionized water, continue to mix and stir for 12min to obtain a self-made dispersion; weigh 24g of nano-montmorillonite and pour it into 80mL deionized water and mix and stir for 4min to obtain a suspension of nano-montmorillonite, and suspen...

Abstract

The invention relates to the technical field of preparation of adhesives and in particular relates to a preparation method of flame-retarding type nail-free glue. The flame-retarding type nail-free glue is prepared by taking polyurethane as a matrix, modified diatomite powder, a self-made dispersion solution and modified nano montmorillonite as a reinforcing agent, and adding amber powder, dimethicone, sodium lauryl sulfate and the like; the modified diatomite, sucrose and yoghurt are commonly fermented and macromolecular saccharides are grafted on the surface of the diatomite under the actionof microorganisms, so that the adhering performance between the diatomite and other filler is enhanced; meanwhile, the strength of the nail-free glue is improved; silicon dioxide has certain flame-retarding performance; melamine is heated to be decomposed so that the expansion of a charring layer is accelerated, heat energy is prevented from being transferred to the matrix and the flame-retardingperformance of the nail-free glue is improved; the nano montmorillonite is continually added, intercalation of a macromolecular substance is facilitated and the regularity of arraying molecules in the matrix is improved, so that the crystallization degree of the nail-free glue is improved; furthermore, the strength of the nail-free glue is improved and the nail-free glue has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of adhesive preparation, in particular to a method for preparing flame-retardant nail-free adhesive. Background technique [0002] Nail-free glue refers to a multi-functional building structure super glue with strong adhesive force, mainly used for bonding and fixing various wood lines, door casing lines, plaster lines, floor tiles, various decorative pendants and various wall board engineering etc. It has the characteristics of fast bonding speed, high strength, wide application range, high solid content, long storage period, and convenient construction. It can replace the traditional nailing construction process. It is generally called liquid nails abroad, and it is called nail-free glue in China. In recent years, nail-free glue has gradually replaced the previous fixing methods such as nailing and drilling used in indoor and outdoor decoration, effectively avoiding noise and dust pollution, and also redu...
