Abstract
The invention discloses a kind of disposable medical articles for use structure glues and preparation method thereof.The disposable medical articles for use structure glue includes the component of following parts by weight：45 85 parts of styrene analog thermoplastic elastomer, 20 50 parts of hydrogenated petroleum resin, 1 10 parts of naphthenic oil, 15 parts of hydroscopic high-molecular resin, 38 parts of amorphous propylene copolymer, 15 parts of antioxidant；The styrene analog thermoplastic elastomer is the compound of SBS and SEBS, and the mixed weight ratio of the SBS and SEBS are 1:0.5‑2.Beneficial effects of the present invention are：The disposable medical articles for use structure glue has good absorbability, can absorb urine in time, reduces the time of contact of skin and urine.
Description
Technical field
The present invention relates to adhesive, more particularly to a kind of disposable medical articles for use structure glue and preparation method thereof.
Background technology
Disposable medical articles for use refer to using primary rear i.e. discarding, with direct body contact and are defended to reach human body
The various medical products given birth to purpose and used, such as：Women sanitary articles (sanitary napkin/protection pad etc.), paper diaper (baby paper diaper and
Adult incontinence products), medical supplies (operating coat/medical mattress, gloves, shoe cover, mask) and pet supplies (pet pads and pet
Urine pants) etc..Many component parts of disposable medical articles for use such as sanitary napkin, paper diaper, medical mattress etc. will borrow structure gluing
Firmly, to form functional structure appropriate.
It is pressure-sensitive that the Chinese patent of Publication No. CN106047287A discloses a kind of disposable sanitary articles low-temperature heat melting
Glue and preparation method thereof.The pressure sensitive adhesive includes following components：Styrene analog thermoplastic elastomer 10-30wt%；Tackifying resin 40-
60wt%；Naphthenic oil 15-35wt%；Antioxidant 0.1-1.0wt%；Wax 0.1-5wt%.
But the Low Temperature Hot-Melt Pressure Sensitive absorbability is poor.In medical disposable product such as sanitary napkin, paper diaper and medical treatment
During the use of mattress, medical disposable product can encounter urine often.Therefore, the absorbent properties of the Low Temperature Hot-Melt Pressure Sensitive
The poor time of contact that can increase skin and urine, have much room for improvement.
Invention content
The object of the present invention is to provide a kind of disposable medical articles for use structure glues.The disposable medical articles for use structure glue has
Good absorbability can absorb urine in time, reduce the time of contact of skin and urine.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of disposable medical articles for use structure glue, includes the component of following parts by weight：
45-85 parts of styrene analog thermoplastic elastomer
20-50 parts of hydrogenated petroleum resin
1-10 parts of naphthenic oil
1-5 parts of hydroscopic high-molecular resin
3-8 parts of amorphous propylene copolymer
1-5 parts of antioxidant；
The styrene analog thermoplastic elastomer is the compound of SBS and SEBS, and the mixed weight ratio of the SBS and SEBS are 1:
0.5-2。
By using above-mentioned technical proposal, SBS and SEBS melt index (MI)s are higher, can assign the certain intensity of structure glue,
Cohesive force and adhesive force.The addition of hydrogenated petroleum resin can improve the wettability of SBS and SEBS, cohesive force, peel strength and
Shear strength increases initial bonding strength and permanent adhesive intensity, reduces the melt viscosity of structure glue, improves the wellability for being glued material,
Improve operating characteristics.Naphthenic oil has the characteristic of paraffinic base and aromatic radical, and emulsibility and compatibility are preferable, and nontoxic, drop
The glass transition temperature of low-styrene analog thermoplastic elastomer improves glue-line brittleness, promotes melt substance mobility, glued membrane is made to have
Flexibility weakens the intermolecular force of polymer, increases the activity of polymer molecular chain, reduces the knot of polymer molecular chain
Crystalline substance.Hydroscopic high-molecular resin, abbreviation SAP are the polyphosphazene polymers of the low crosslinking degree or partially crystallizable with many hydrophilic radicals
Object is closed, own wt can be absorbed hundreds times, even thousands of times of water, there is very strong water holding capacity.Amorphous propylene is copolymerized
Object, commonly referred to as APAO are the random copolymers obtained by alpha-olefine polymerizing.APAO molecular weight is relatively low, and random degree is higher, tool
There are excellent high temperature performance, water resistance, anti-oxidant uvioresistant performance.There are unsaturated double-bonds for the rubber segment of SBS, in sky
Thermo-oxidative ageing is occurred by the effect of oxygen, ozone and ultraviolet light in gas, especially structure glue is prepared and melted in high temperature and applies
When cloth, SBS agings are even more serious, cause oxidation cross-linked or oxidative degradation, and the performance of adhesive is made to decline.The addition energy of antioxidant
Enough promote the ageing-resistant performance of SBS.
The present invention is further arranged to：The antioxidant is antioxidant 1010 or antioxidant 330.
By using above-mentioned technical proposal, antioxidant 1010 and antioxidant 330 are hindered phenol anti-oxidants, nontoxic nothing
Pollution, it is not colored.
The present invention is further arranged to：It further include the natural perfume material that parts by weight are 1-2 parts.
