Description
Technical field
The present invention relates to bonding technique field, in particular to paper diaper one-time fix ring waist patch glue.
Background technique
Paper diaper are common one of the products of infant's consumer goods market, and are not only comfort or safety is
The direction that consumer pays close attention to, while the comfort level used is also one of consumer's focus, thus it is most in the market
Paper diaper use removable bonding way, are easy to use also easy to dismantle.
Likewise, the requirement for the fixed ring waist patch of paper diaper is also extremely important, not only need to meet enough bondings
Intensity can satisfy the routine use of baby and need the normal activity and movement in view of baby, and mother and baby's articles
Safety also want can to obtain enough guarantees.In view of this, a kind of new technical solution is provided.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of paper diaper to one-time fix ring waist patch
With glue, while having stronger adhesion strength, safety is higher.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of paper diaper one-time fix
Ring waist patch glue, the component comprising following parts by weight: 33-35 parts of styrene analog thermoplastic elastomer；Tackifying resin 35-50
Part；22-34 parts of polyolefin；1.5-3 parts of anti-aging agent group；10-15 parts of softening agent.
By using above-mentioned technical proposal, obtained finished product softening point is higher to can achieve 120 DEG C or so, can be with resistance to height
Temperature, so that use scope is wider, while stability is high, not oxidizable jaundice, robust consistent, and does not contain solvent material
Material, does not volatilize, and is free of fluorescence, and component sensitization is low, and safety is higher, is suitable for mother and baby's articles.
The further setting of the present invention are as follows: the styrene analog thermoplastic elastomer is the compound of SIS and SEBS, and institute
The mass ratio for stating SIS and SEBS is 1:18-20.
By using above-mentioned technical proposal, one isoprene of styrene, one styrene block copolymer (SIS) has excellent
Bellow seal and high temperature retentivity, unique Microphase Separation structure determine it when being used as adhesive have it is unique
Superiority, and SEBS is using polystyrene as end segment, the ethylene-butene copolymer obtained with polybutadiene plus hydrogen is intermediate bullet
Property block linear tri-block copolymer, SEBS is free of unsaturated double-bond, therefore with good stability and resistance to ag(e)ing is chosen
Adhesive property can be increased adequately with adherency object contact both as pressure-sensitive gum base materials.
The further setting of the present invention are as follows: further include the shallow white conductive powder that parts by weight are 5-10 parts.
By using above-mentioned technical proposal, the shallow white conductive powder of model SHDT-1SHDT-2SHDT-3, generally by more
Kind super-fine material is made by organic composite, and main component is that composite materials, the TiO2 such as composite materials, the TiO2 such as SnO2 etc. are compound
Material, shallow white conductive powder have easy dispersion, heat-resisting quantity, high stability, corrosion resistance and good conductivity, mix to
When in product, it can assign pressure sensitive adhesive good antistatic property, it, can be with when infant in use can be arbitrarily active
Effectively avoid the frictional static generated.
The further setting of the present invention are as follows: the anti-aging agent group includes phenol antiager, peroxide decomposer and ultraviolet
Absorbent.
By using above-mentioned technical proposal, due to the C-H bond of double bond alpha-position in the molecular structure of tackifying resin be easy by
The attack of oxygen or other oxidation materials in air generates free radical, and free radical can further cause macromolecular chain break
And degradation, in order to restrain or delay the process, the phenol antiager of use can be reacted with the various free radicals of generation, raw
At stable compound, to prevent the further degradation of macromolecular chain；Peroxide decomposer can then decompose oxidation in time
The peroxide generated in the process, effectively prevent peroxide further oxidation, thus reach prevent macromolecular chain into
One step degradation process；Ultraviolet absorber can then absorb ultraviolet light, can also reduce the generation of big free radical to a certain extent.
Therefore above-mentioned three kinds of antioxidants are used, through the cooperation between them respectively at different action principles, are carried out different
It is anti-oxidant, the inoxidizability of product is improved to the full extent.
The further setting of the present invention are as follows: the softening agent is at least one of naphthenic oil and atoleine, the increasing
Viscosity resin is C5 hydrogenated petroleum resin.
It by using above-mentioned technical proposal, selects and hydrogenates complete petroleum hydrogenated resin, color is clear shallow and nontoxic, meets doctor
With requiring, and hydrogenated resin molecular link after hydrotreating forms stable double bond, is easily saturated, and chemical property is stablized, therefore
Photostability is stronger, non-aging.Softening agent imparts the preferable mobility of hot-fusible pressure-sensitive adhesive, enable after hot melt colloid more
It is good with attachment surface adhesion, increase contact area and cohesive force, while atoleine has low irritability and good envelope
Closing property, while as softening agent, the finished product after capable of being also coated with for hot melt adhesive provides good moisture protection, reduces bacterium and grows
It is raw.
The further setting of the present invention is that paper diaper one-time fix ring waist patch and are prepared with glue by following steps:
Step 1: raw material preparation weighs 33-35 parts of styrene analog thermoplastic elastomer, C5 hydrogenated petroleum resin according to parts by weight

Controlling reaction vessel temperature is 145-150 DEG C until C5 hydrogenated petroleum resin and styrene analog thermoplastic elastomer melting are complete；
Step 4: control reaction vessel temperature is 165-170 DEG C, and polyolefin is first added and is reacted, after reaction to polyolefin melting completely
Remaining styrene analog thermoplastic elastomer, remaining C5 hydrogenated petroleum resin and shallow white conductive powder is added to be reacted,
Reaction completely, forms first product to styrene analog thermoplastic elastomer, the melting of C5 hydrogenated petroleum resin；
Step 5: stop stirring, after first product is stablized, discharging；
Step 6: filtering, cooling, packaging.
By using above-mentioned technical proposal, tackifying resin and thermoplastic elastomer (TPE) are that reaction is added in front and back twice when reaction
In container, not merely for the purpose for slowing down reaction vessel stirring pressure, while relatively disposable be all added more can be improved raw material
Conversion ratio, be conducive to reaction is normally carried out.
The further setting of the present invention are as follows: C5 hydrogenated petroleum resin and styrene analog thermoplastic elastomer in the step 3
A length of 25-35min when melting, a length of 8-12min when the melting of polyolefin in the step 4, phenylethylene heat in the step 4
