[0026] The preparation method for preparing the traceless removable viscose by above-mentioned curable precursor composition comprises the steps:

[0027] S1, vacuumize the first reaction component with a vacuum pump for 5min-60min; preferably, vacuumize with a vacuum pump for 15min-30min, the purpose of vacuumizing is to eliminate air bubbles and part of the moisture;

[0028] S2. Mix the second reaction component with the first reaction component after vacuuming; wherein, the mass ratio between the first reaction component and the second reaction component is required to be 100:5-48, preferably, The mass ratio between the first reaction component and the second reaction component is 100:15-35;

[0029] S3. Reaction curing is carried out under the condition of 40°C-95°C to obtain a traceless removable adhesive, and the curing time is 1min-60min; preferably, the reaction curing is carried out under the condition of 50°C-80°C, and the curing time is 5min-10min.

Abstract

The invention relates to traceless movable viscose glue, a solidifiable precursor composition thereof, and a preparation method of the traceless movable viscose glue. The traceless movable viscose glue contains a first reaction component and a second reactioncomponent, wherein the first reaction component contains a polyetherpolycolcomponent and a catalyst component; the polyetherpolycolcomponentcomprisespolyethertriol and polyether diol; and the second reaction component contains an isocyanate component. Thetraceless movable viscose glue has high viscosity, can be used on the wall surface of a smooth plane, and alsobe stably adhered to otherunsmooth and slightly convex-concave wall surfaces and meet the weight hanging requirement, and can move tracelessly to realize reuse, avoid residues on the wall surfaces, and still maintain the original viscosity and be used continuouslyafter being washed with water, thereby having a wide application range.

Description

technical field [0001] The invention relates to the technical field of viscose, in particular to a traceless removable viscose and its curable precursor composition and preparation method. Background technique [0002] At present, most of the hooks sold in the market use SEBS material adsorption, 3M adhesive paste, suction cup vacuum adsorption and other methods to achieve the hanging weight requirements. Due to the limitation of pasting methods and materials, they rely on compressed air adsorption or glue bonding to achieve adhesion. Effect, can only be applied on smooth flat walls, can not be used on non-smooth or slightly concave-convex walls, and basically only one-time use, can not be removed for repeated use, will be left on the wall when it is removed after pasting Adhesive remains and the range of application is limited. Contents of the invention [0003] The purpose of the present invention is to provide a traceless removable viscose and its curable precursor com...
