Problems solved by technology

At present, there are some such sealant products, but each of the existing sealant products can only be aimed at a specific substrate, which makes the applicability of the sealant products narrow, and the use of different products is limited in terms of sanitation and wide applicability. The product cannot be widely used

Abstract

The invention discloses a normal temperature adhesive composition, which comprises emulsion one, emulsion two, an anti-adhesion agent, a wetting agent, an antioxidant, a defoaming agent, ammonia and water, wherein the emulsion one is one of acrylosilane emulsion, pure acrylic emulsion, styrene-acrylate emulsion, vinyl acetate / acrylic emulsion and vinyl acetate-acetate copolymer emulsion; the molecular weight of the emulsion one is smaller than 100,000 and the glass state temperature thereof is between -2 and +45DEG C; the emulsion two is one of polyacrylic emulsion, SIS latex and natural latex; and the molecular weight of the emulsion two is between 300,000 and 1,000,000, and the glass state temperature thereof is between -50 and -80DEG C; and the raw materials are added one by one, and the mixture is mixed, stirred, dispersed evenly to prepare the normal temperature adhesive composition. The sealing composition finally achieves effective sealing under the condition of different sealing pressures by properly adjusting a ratio of an adhesion system to a pressure-sensitive system according to different sealing conditions.

Description

technical field [0001] The invention relates to an emulsion polymerization composition, in particular to a water-based normal-temperature adhesive composition and a preparation method thereof. Background technique [0002] Various sealing glues are often used in the packaging and sealing of some products, but generally in the sealing packaging, it is often carried out at a certain temperature, but because the packaged products are different, the packaging and sealing of some products cannot be carried out at a higher temperature, such as The packaging and sealing of chocolate, the packaging and sealing of medical auxiliary materials such as band-aids, etc., the performance of these products determines that they cannot be carried out at higher temperatures, and the adhesive sealing system is required to be sealed only at room temperature and under certain pressure conditions. . At present, there are some such sealant products, but each of the existing sealant products can on...
