Hot melt pressure sensitive adhesive for disposable toilet seat

Disposable toilet seat hot melt pressure sensitive adhesive is used to coat the surface of disposable toilet seat material, is used to prevent the primary toilet seat material on the plastic toilet gasket slip dislocation, and plays a fixed role in the hot melt adhesive.

However, at present, with the improvement of people’s comfort requirements, the market began to use non-woven materials with better skin affinity to replace paper materials to make disposable toilet MATS. However, because the adhesion between skin-friendly materials and skin is much greater than that between materials and toilet washers, the user experience is greatly affected. In view of this, in order to improve the user experience of the product, a kind of hot-melt pressure-sensitive adhesive that is harmless to the human body and environmentally friendly is needed to improve the adhesion between toilet mat material and toilet washer, while there is no residue of hot-melt adhesive when uncovering.

The steps include: (1) putting the naphthenic oil and the antioxidant into a stainless steel reactor; (2) When the temperature rises to 140℃, SBR rubber is added and the temperature of the reactor is controlled at 150℃; (3) after being SBR rubber completely dissolved in hydrogenated C5 / C9 copolymerized petroleum resin and modified aromatic C9 petroleum resin, styrene – acrylate, stainless steel reaction kettle temperature control at 200 ℃ within 30 to 60 min, stir vacuum to  0. 085 mpa, discharge the cooling package.

Beneficial effect: The hot-melt pressure-sensitive adhesive for the toilet gasket prepared in this paper can maintain excellent coating performance and at the same time has excellent cohesion strength. Meanwhile, the product of the invention has good infiltration on the substrate and excellent experience performance. hydrocarbon resin described in this paper is a thermoplastic resin produced by pretreatment, polymerization, and distillation of C5, and C9, which is a by-product of petroleum cracking. It is not a polymer, but an oligomer with a molecular weight between 300-3000. According to the different raw materials, petroleum resin can be divided into aliphatic resin (C5), aliphatic resin (DCPD), aromatic resin (C9), aliphatic/aromatic copolymer resin (C5/C9), and hydro petroleum resin.
