Abstract
The invention provides a hot-melt adhesive with excellent heat resistance and a hot-melt adhesive tape. The hot-melt adhesive comprises the following components by weight percent: 25-35% of thermoplastic elastomer, 15-25% of softening oil, 40-50% of resin, 1-3% of antioxidant, and 3-8% of functional packing. The hot-melt adhesive is prepared by selected materials and a formula, the cohesive strength and heat resistance of the hot-melt adhesive are improved by a physical method, so that the hot-melt adhesive tape does not have phenomena of excessive glue and residual glue in heat environment.
Description
Technical field
The present invention relates to a kind of hot melt pressure-sensitive adhesive and hot melt pressure-sensitive adhesive tape, relate in particular to a kind of glue that can not overflow that hot melt pressure-sensitive adhesive makes, hot melt pressure-sensitive adhesive tape of cull not of using under hot environment.
Background technology
Hot melt pressure-sensitive adhesive tape mainly becomes molten molten state by synthetic rubber with resin and rubber wet goods Hybrid Heating, then is coated on the base materials such as cotton paper, cloth or plastics film and make.With low cost is its maximum advantage, and defect is that its viscosity temperature influence is more obvious.Hot melt pressure-sensitive adhesive tape is mainly used in all kinds of joint sealings, envelope box, paper article packaging, beverage bottle label, sealing aluminium foil, soft packaging and other packaging, environment protecting paper pallet etc., adapts to all kinds of materials.
Existing hot melt pressure-sensitive adhesive is to be mainly grouped into by one-tenth such as thermoplastic elastomer (as SIS, SBS etc.), softening oil, resin, antioxidants.Wherein, its main component is exactly thermoplastic elastomer SIS or SBS.They are all segmented copolymers, although have the elasticity of thermoplasticity and rubber, creep property is good, are suitable for preparing hot melt pressure-sensitive adhesive, due to some characteristics of himself, make the hot melt pressure-sensitive adhesive tape resistance toheat made poor.
At present hot melt pressure-sensitive adhesive be by above-mentioned each component through being heated to 160 ℃, its fusing physics is mixed.Then under the high temperature of 160 ℃ of left and right, guarantee that it is the operation that flow-like is just coated with.Hot melt pressure-sensitive adhesive tape after being coated with is prone to the glue phenomenon of overflowing under hot environment, and adhesive tape is peeled off and is prone to cull from affixed object.Because be subject to the restriction of manufacture and coating process condition, hot melt pressure-sensitive adhesive is difficult to adopt the mode of chemically crosslinked to form required network structure, thereby is difficult to obtain good temperature tolerance.Under existing processing condition, the in the situation that of long-time heat, chemical crosslink reaction is uncontrollable, and feasibility is not good.
For above-mentioned defect, be badly in need of a kind of brand-new hot melt pressure-sensitive adhesive of invention and hot melt pressure-sensitive adhesive tape and solve the deficiencies in the prior art.
Summary of the invention
The object of the present invention is to provide a kind of hot melt adhesive and Hot melt adhesive tape of excellent heat resistance.
To achieve these goals, the application discloses a kind of hot melt adhesive of excellent heat resistance, and the weight percent of described each component of hot melt adhesive is as follows: thermoplastic elastomer: 25 ~ 35%; Softening oil: 15 ~ 25%; Resin: 40 ~ 50%; Antioxidant: 1 ~ 3%; Functional filler: 3 ~ 8%.
As a further improvement on the present invention, described multi-functional filler is loose and porous structure, and through coupling agent treatment.
As a further improvement on the present invention, described thermoplastic elastomer comprises one or both in SIS and SBS.
As a further improvement on the present invention, described softening oil comprises one or several in naphthene base crude oil, liquid polybutadiene and base modifier.
As a further improvement on the present invention, described antioxidant is composite antioxidant.
As a further improvement on the present invention, described resin softening point is not less than 95 ℃.
As a further improvement on the present invention, described hot melt adhesive softening temperature is not less than 85 ℃.
As a further improvement on the present invention, described hot melt adhesive is in 150 ℃ of environment lower times, and its brookfield viscosity is not less than 11000Cps.
To achieve these goals, disclosed herein as well is a kind of Hot melt adhesive tape, the hot melt adhesive as above that comprises substrate and be coated at least one side of substrate.
The present invention compared with prior art has following beneficial effect:
Hot melt adhesive provided by the invention and Hot melt adhesive tape be by choose reading materials and formulating of recipe, improves cohesive strength and the thermotolerance of hot melt adhesive with physical method, makes Hot melt adhesive tape under hot environment, do not overflow glue, cull not.
Embodiment
For the application's above-mentioned purpose, feature and advantage can be become apparent more, below the application is described in further detail.
Present embodiment provides a kind of hot melt pressure-sensitive adhesive of excellent heat resistance, and the weight percent of described each component of hot melt pressure-sensitive adhesive is as follows: thermoplastic elastomer: 25 ~ 35%; Softening oil: 15 ~ 25%; Resin: 40 ~ 50%; Antioxidant: 1 ~ 3%; Functional filler: 3 ~ 8%.
Wherein, described multi-functional filler is loose and porous structure, and through coupling agent treatment.Described thermoplastic elastomer comprises one or both in SIS and SBS.Described softening oil comprises one or several in naphthene base crude oil, liquid polybutadiene and base modifier.Described antioxidant is composite antioxidant.Described resin softening point is not less than 95 ℃.
The softening temperature of the hot melt pressure-sensitive adhesive of producing according to above-mentioned formula is not less than 85 ℃.When it is in 150 ℃ of environment lower times, its brookfield viscosity is not less than 11000Cps.
Present embodiment also provides a kind of hot melt pressure-sensitive adhesive tape of excellent heat resistance, the hot melt pressure-sensitive adhesive that described hot melt pressure-sensitive adhesive tape comprises substrate and is coated at least one side of substrate.
Provide some concrete experimental datas better to confirm technique effect of the present invention below.
Experiment form:
From above-mentioned experimental data, can find out, the hot melt pressure-sensitive adhesive in the present invention has higher softening temperature, and when its lower time of environment in 150 ℃, brookfield viscosity value is still very high, illustrates that this tackiness agent has good thermotolerance.Glue, cull not do not overflow under hot environment with the adhesive tape of its production.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
