Abstract

The invention discloses organic silicon modified wood floor glue and a preparation method thereof. The organic silicon modified wood floor glue is prepared from the following raw materials in parts by mass: 100 parts of organic silicon modified resin, 60-90 parts of plasticizer, 200-500 parts of calcium carbonate, 2-10 parts of coupling reagent and 0.1-2.2 parts of catalyst. The organic silicon modified resin is adopted for guaranteeing the extensive adhesion of an adhesive; the organic silicon modified wood floor glue has the excellent weather-proof and anti-seismic properties of silicone adhesive, is free from toxicity, solvent and isocyanate and is low in VOC release volume; after being cured, the organic silicon modified wood floor glue is free from shrinkage and foaming; the applicable temperature scope is from -40 DEG C to 60 DEG C; a low-molecular-weight hydrophilic polyalcohol is taken as a plasticizer, so that the hydrophilic property of the cured glue is increased while the hydrolytic resistance is reduced; and the environment-friendly degumming separation can be performed in the manner of soaking in water and the wood floor can be easily replaced.

Description

technical field [0001] The invention relates to an organosilicon modified wood floor adhesive and a preparation method thereof, belonging to the technical field of organosilicon polymer building materials. Background technique [0002] Wooden floor glue is an adhesive used for home decoration and laying wooden floors. Elasticity, flexibility and strong adhesion are prerequisites for accommodating the deformation of wooden floors. Excellent wood floor glue has the characteristics of elasticity, strong adhesion, high environmental protection, and easy construction. 中国专利文献号CN104312462A、CN104293250A、CN104312442A、CN104277725B、CN104277719B、CN104497895A、CN104403586A、CN104403614A、CN105778838A、CN105802518A、CN104893592A、CN104845536A、CN105368353A等中所述木质地板胶,存在一个共同的特点是固化后胶粘剂硬脆,弹性 not enough.
