Organic silicon modified water-based PA adhesive emulsion for shading curtain coating and preparation method thereof

Abstract

The invention discloses an organic silicon modified water-based PA adhesive emulsion for a shading curtain coating and a preparation method of the organic silicon modified water-based PA adhesive emulsion, which belong to the field of polymer functional materials. The water-based adhesive emulsion comprises the following components: an acrylate monomer, acrylic acid, a functional monomer, an organic silicon monomer, an initiator, an emulsifier and deionized water. The preparation method comprises the following steps of: the acrylate monomer is subjected to free radical emulsion polymerization;the silicone monomer is added, the organic silicon modified water-based polyacrylate emulsion is obtained; according to the emulsion, the organic silicon monomer is added to participate in reaction;the compatibility and stability of the water-based PA emulsion with titanium dioxide, kaolin and other fillers are improved, the coating fastness and water resistance fastness are improved, the hole sealing performance is improved, the coating gluing amount is reduced, the cost is reduced, the product competitiveness is improved, in addition, due to the fact that the gluing amount is reduced (thefastness is not reduced), the finished product is softer and more comfortable in hand feeling, and the quality is improved.

Description

Technical field [0001] The invention relates to an organic silicon modified water-based PA glue emulsion used for coating of shading curtains and a preparation method thereof, belonging to the field of polymer functional materials. Background technique [0002] Curtains are a facility in every household. The main function of curtains is to isolate from the outside world and keep the privacy of the room. At the same time, it is an indispensable decoration for home decoration. In winter, curtains divide the interior and exterior into two worlds, adding warmth to the house. Modern curtains can not only reduce light and shade to meet people's needs for different intensities of light; but also can prevent fire, wind, dust, warmth, noise reduction, heat insulation, radiation protection, UV protection, etc., to improve the climate and environment of the room. Therefore, the ingenious combination of decoration and practicality is the biggest feature of modern curtains. [0003] Silver-c...

Problems solved by technology

Existing silver powder coating materials will turn black or corrode after long-term use, and are also prone to discoloration due to alkaline water washing

In addition, the existing silver powder coating has limited shading effect and general adsorption effect. For the shading effect and service life, manufacturers often apply more than one layer of coating on the fabric

This behavior will cause silver-coated curtains to emit a certain pungent smell after being exposed to direct sunlight for a long time. It contains certain toxic components, such as silver powder, which may cause irreversible harm to the human body if used for a long time

In order to avoid the harm of silver powder, some manufacturers use aluminum powder instead of silver powder to achieve similar effects, but aluminum powder is not easy to characterize, and it is easy to fall off after a long time, which makes the appearance of silver-coated curtains unattractive

[0004] At present, some water-based PA adhesives are used on curtain coatings. In order to achieve full shading requirements, coating manufacturers often add titanium dioxide, kaolin, talcum powder and other fillers to achieve the shading effect. Due to the polarity of PA water-based adhesives and fillers The compatibility of different types is not good, and the mixed type is prone to poor dispersion of fillers and poor stability, so that the coating will appear light-transmitting spots, poor light-shielding and hole-sealing properties, and quality decline
