Abstract

The invention discloses an environment-friendly hot-melt pressure-sensitive adhesive, comprising 380-420 parts by mass of hydrogenated C5 petroleum resin, 330-370 parts by mass of plasticizer, 180-220 parts by mass of thermoplastic elastomer SBS, 15-20 parts by mass of antioxidant and 15-20 parts by mass of softener. The environment-friendly hot-melt pressure-sensitive adhesive has moderate adhesion performance; and the hydrogenated and modified C5 petroleum resin serves as a tackifier, so that the problems of deep color and low flowability of a product produced by using C5 petroleum resin as a tackifier are solved, and the hot-melt pressure-sensitive adhesive is suitable for the industries of tags, hygiene products and the like.

Description

Environment-friendly type hot melt pressure sensitive adhesive

Technical field

The present invention relates to hot-fusible pressure-sensitive adhesive field, specifically a kind of environment-friendly type hot melt pressure sensitive adhesive.

Background technology

Along with modern economy develop rapidly, people's quality of life improves constantly, and to the demand of daily necessities also in continuous lifting, except the requirement for product performance, the theory of safety and environmental protection is also rooted in the hearts of the people.Hot-fusible pressure-sensitive adhesive has hot melt and pressure-sensitive dual property, is coated with in the molten state, cools after-applied light pressure and gets final product quick-binding.

C5 petroleum resin have the performance advantage of excellent, safety, environmental protection, be a kind of low relative molecular mass, thermoplastic resin, there is pour point depression, increase the performance sticking and improve viscosity, can be used as the viscosity increaser in SBS thermotropic pressure sensitive glue, play and improve colloid original viscosity, improve the effects such as colloid wettability.But C5 petroleum resin color of resin is comparatively dark, containing unsaturated link(age), is very easily oxidized in reaction process, finally cause the product color produced dark, mobility is poor, thus limits its application in this field of hot-fusible pressure-sensitive adhesive.

Summary of the invention

For the deficiencies in the prior art, the object of the present invention is to provide a kind of environment-friendly type hot melt pressure sensitive adhesive, by C5 petroleum resin are carried out hydrogenation modification, solve the problem that product color is dark, mobility is poor that C5 petroleum resin are produced as viscosity increaser.

In order to achieve the above object, the present invention is by the following technical solutions: a kind of environment-friendly type hot melt pressure sensitive adhesive, it is by 380 ~ 420 mass parts hydrogenation C5 petroleum resin, 330 ~ 370 mass parts softening agent, 180 ~ 220 mass parts thermoplastic elastomer SBSs, 15 ~ 20 mass parts oxidation inhibitor and 15 ~ 20 mass parts tenderizers composition.

Described softening agent is preferably whiteruss.

Described oxidation inhibitor is preferably 2,6-, tri-grades of butyl-4-methylphenols.

Described tenderizer is preferably naphthenic oil.

In hot-fusible pressure-sensitive adhesive of the present invention, hydrogenation C5 petroleum resin are reduce viscosity as the effect of viscosity increaser, and the force of cohesion of hot-fusible pressure-sensitive adhesive is strengthened, and adhesive power declines; Softening agent can increase the reactivity of polymer molecular chain, weaken polymkeric substance in hot-fusible pressure-sensitive adhesive intermolecular in, improve elongation, flexibility and snappiness, and then improve the mobility of hot-fusible pressure-sensitive adhesive, thus reduce hot melt viscosity; For improving oxidation-resistance and the use properties of hot-fusible pressure-sensitive adhesive of the present invention, overcoming the shortcomings such as poor stability, also adding a small amount of oxidation inhibitor and tenderizer.

Containing polybutadiene segments on the main chain of thermoplastic elastomer SBS, at a certain temperature, polybutadiene segments is easy to occur crosslinked, thus the viscosity of hot-fusible pressure-sensitive adhesive is increased, but has excellent tensile strength and elasticity due to SBS, set resistant is little, it is good to subdue with rebound resilience, and skin friction force is large, so under the prerequisite not affecting hot-fusible pressure-sensitive adhesive mechanical property, choose suitable add-on, have good effect to the lifting of hot-fusible pressure-sensitive adhesive performance.

The invention has the beneficial effects as follows: environment-friendly type hot melt pressure sensitive adhesive of the present invention adheres to moderate performance, viscosity increaser is re-used as after C5 petroleum resin are carried out hydrogenation modification, solve the problem that product color is dark, mobility is poor that C5 petroleum resin are produced as viscosity increaser, be applicable in the industry such as label and sanitary product.
