preparation example Construction

[0079] In one embodiment, the preparation method of the sterilizing emulsion pressure-sensitive adhesive comprises the steps:

[0080] (1) uniformly mixing acrylate monomer, N methylol acrylamide, molecular weight regulator, surfactant and deionized water to obtain emulsion;

[0081] (2) heating the reactor to 80°C, taking 6wt% of the emulsion described in step (1) and adding it to the reactor, then adding an initiator, polymerizing for half an hour as a seed, then adding the remaining step (1) described The emulsification is added dropwise to the reaction kettle for 4 hours, the temperature is kept for 1 hour, and the temperature is lowered to 45 ° C. The treatment agent is added, stirred, and then glacial acetic acid is added to adjust the pH to 5-6. The bactericidal emulsion pressure-sensitive adhesive.

[0082] A second aspect of the present invention provides a sticky dust pad containing the above-mentioned sterilizing emulsion pressure-sensitive adhesive.

[0083] A th...

Abstract

The invention relates to the technical field of dust-sticking pads, in particular to a bactericidal emulsion pressure-sensitive adhesive, a dust-sticking pad and a preparation method of the dust-sticking pad. The bactericidal emulsion pressure-sensitive adhesive at least comprises the following components in parts by weight: 900 to 1100 parts of acrylate monomers, 0.2 to 2 parts of molecular weight regulators, 10 to 80 parts of surfactants, 0.01 to 0.05 parts of an initiator and 1200 to 1400 parts of deionized water, wherein each surface active agent comprises a quaternary ammonium salt surface active agent. The dust-sticking pad provided by the invention is good in sterilization and antibacterial effect and excellent in dust-sticking effect, a quaternary ammonium salt surfactant is addedas an emulsifier, so that sterilization effect is improved, reaction stability is better, comprehensive performance of a formed pressure-sensitive adhesive is very good, the interface adhesive force and peel strength of the pressure-sensitive adhesive are increased, and the adhesive force and peel strength of the pressure-sensitive adhesive are improved so that unwinding force of the dust-stickingpad is 0.8 to 1.3 N, and the 180 degree stripping force of the dust-sticking pad is 1.5 to 5.5 N.

Description

technical field [0001] The invention relates to the technical field of sticky dust pads, and more particularly, to a sterilizing emulsion pressure-sensitive adhesive, a dust sticky pad and a preparation method thereof. Background technique [0002] The sticky mat, also known as the sticky floor glue, is mainly suitable for sticking at the entrance of the clean space and between the buffer zones. It can effectively remove the dust on the soles and wheels, and minimize the impact of dust on the quality of the clean environment. In this way, the effect of simple dust removal is achieved, and the problem that the dust removal of other floor mats is not completely can not ensure that the dust does not spread is solved. [0003] At present, the relatively mature antibacterial and antibacterial dust sticky pads on the market use conventional anionic or anionic nonionic acrylate emulsions as dust sticky pressure-sensitive adhesives, and such acrylate emulsions do not have any bacter...
