Embodiment 1
[0058] S-90 (S-90 represents a molecular weight of about 9000, purchased from Hanwha Corporation in Korea) 13 parts by weight;
[0059] Water 82.38 parts by weight;
[0060] 3.3 parts by weight of propylene glycol
[0061] Xanthan gum 0.72 parts by weight;
[0062] 0.2 parts by weight of silicone defoamer;
[0063] PX type fungicide 0.4 parts by weight.
[0064] Put the water-soluble resin into the water, heat it to 70-80°C under stirring to dissolve it, and add the defoamer at the same time, after the dissolution is completed, cool it down to below 60°C, add the thickener that has been dissolved in advance while stirring, and finally Put in humectants, bactericides and other auxiliary ingredients, mix evenly, discharge, and filter through a 120-mesh sieve to obtain the required sealing glue.

Abstract
The invention provides a water-based pseudoplastic sealant composition, which comprises 10.52 to 16.92 weight parts of pseudoplastic component, 82.38 +-30 weight parts of water, 3.3+-2 weight parts of humectants, 0.2+-0.1 weight part of defoamer and 0.4+-0.1 weight part of bactericide, wherein the pseudoplastic component consists of a film-forming polymer and a thickener; the mixing ratio of the film-forming polymer and the thickener is (10-16):(0.52-0.92); the film-forming polymer is styrene-modified water soluble acrylic resin; and the number-average molecular weight of the resin is 7,000 to 12,000.
Description
technical field [0001] The invention relates to a sealant, in particular to a water-based pseudoplastic sealant. Background technique [0002] Sealant is a kind of sealing material that deforms according to the shape of the sealing surface, is not easy to flow, and has certain adhesiveness. Adhesive used to fill gaps in configurations for sealing. It has the functions of preventing leakage, waterproof, sound insulation and heat insulation. General sealants contain thermosetting resins such as epoxy resins, curing agents, curing accelerators and fillers, etc., requiring heat curing. In addition, the sealant can be divided into one-component, two-component and multi-component sealants, and the curing speed is fast. These have caused inconvenience to production. As the sealing material for ink-erasable copper tubes and tail plugs, in order to meet production needs, it is required that the sealing glue does not dry or dries slowly, but at the same time it can achieve the sea...
