Property it is good, rigidity is big, heat-resisting, cold resistance is good the advantages that, also there is good environmental stress crack resistance, impact resistant strength resistance to is torn
The performances such as resistance to spalling, and can acid and alkali resistance, organic solvent etc.；The LLDPE plastic body (MLLDPE) of Metallocenyl has tradition
Modified pitch is added in average comonomer content of the LLDPE more than 3 times, tackifier (PIB), passes through diffusion into the surface or internal diffusion
Wet gluing of surfaces improves adhesive strength between modified pitch and adherend material, thus improves whole adhesive effect；It will
LLDPE combination MLLDPE, improves whole reliability, and the rear PIB tackifier that put into improve whole adhesive strength, in use not
Need to add glue use, use intensity is high, and adhesive effect is good.
In the present embodiment 1, floor mat body 100 from bottom to top successively include substrate layer 110, liquid hot melt glue 111, it is compound from
Mucous membrane 120, printing pattern layer 130 and transparent print film 140 are saved material technology, are simple to manufacture for the ground cushion that is printed on one side, at
This is cheap, practical；
In the present embodiment 2, place unlike the embodiments above is that floor mat body 100 successively includes transparent print from bottom to top
Brush film 140, composite self-adhering film 120, liquid hot melt glue 111, substrate layer 110, liquid hot melt glue 111, is answered at printing pattern layer 130
Close self-adhesive film 120, printing pattern layer 130 and transparent print film 140, be arranged for double-side pattern ground cushion, use scope is wide, it is two-sided can
It uses, whole service life is longer.
In a first aspect, being equipped with floor mat body 100, the floor mat body 100 successively includes substrate layer 110, answers from bottom to top
Self-adhesive film 120, printing pattern layer 130 and transparent print film 140 are closed, realizes substrate support effect particular by substrate layer 110,
It aloows printing pattern layer 130 to be connected with 110 self-adhesion of substrate layer by the effect of composite self-adhering film 120, does not need to pass through
Glue bonding, is greatly improved production efficiency, reduces production cost, transparent print film 140 is coated or printed on printed patterns
130 surface of layer form transparent protective film to printing pattern layer 130, and protecting effect is good, improves wearability and use intensity；Second
Aspect, the printing pattern layer 130 bond with composite self-adhering film 120 by the way that hot pressing is compound, are connected by the way that hot pressing is compound, bonding effect
Fruit is good, and integraty is strong, high production efficiency, does not need glue bonding, reduces production cost；The third aspect, the composite self-adhering film
120 bond by the way that hot pressing is compound with substrate layer 110, are connected finally by hot pressing is compound, by composite self-adhering film in hot pressing
120 is Nian Jie with substrate layer 110 by the effect of hot pressing, is greatly improved adhesive effect, to solve through glue bonding
At high cost, the problems such as low efficiency, adhesive effect is bad, exists, while also greatly improving service life, and integraty is stronger.
A kind of manufacturing method of the composite floor cushion of hot pressing self-adhesive film, comprising the following steps: step 1, prepare printing membrane material
And foaming layer, the printing membrane material include composite self-adhering film 120, printing pattern layer 130 and transparent print film 140；Step 2, will
The layer surface that foams in step 1 coats upper liquid body heat melten gel 111；Step 3, by the printing pattern layer of step 1 130 and transparent print film
140 are bonded into one；Step 4, composite self-adhering film 120 is warm by printing pattern layer 130 and the liquid of foaming layer by hot-pressing roller
Melten gel 111 bonds, i.e., completion composite floor cushion is hot-forming；Hot pressing roll temperature is controlled at 120 DEG C~150 DEG C in the step 4,
In hot pressing, control temperature is at 130 DEG C, and effect is so that liquid hot melt glue 111 dissolves, while composite self-adhering film 120 is molten
Solution point is 100 DEG C, foaming layer and the bonding of printing pattern layer 130 can be formed one, produced multiple using this manufacturing method
Closing ground cushion has at low cost, high production efficiency, the strong advantage of integraty.
In the step 1, the manufacturing method of composite self-adhering film 120 the following steps are included:
Step a, the master batch of composite self-adhering film 120；
Step b squeezes out the master batch prepared in step a investment extruder；
The master batch prepared in the step a is with 70~90 parts of LLDPE, and 10~30 parts of MLLDPE with 2~4 parts of PIB with weight
Amount matches the master batch that composite self-adhering film 120 is made；
Composite self-adhering film 120 using above method manufacture has high-intensitive adhesive effect, does not need in use again
It adds glue and realizes bonding, adhesive effect is good, can save the time of production cost, improve efficiency, and saves energy consumption.
In the step b, the heating temperature of extruder is respectively 130~180 DEG C of bringing-up section, and 170~200 DEG C of fluxing zone,
190~220 DEG C of metering section, 200~230 DEG C of die head heating temperature；Mouth mold gap is 1.2~1.5mm, is propelled the price of than being 1:2.53；
10~40 DEG C of film roll reserve temperature, a further improvement is that, extruder screw revolving speed is to step up to 60~70rpm, mouth mold
Heating temperature at control temperature and speed conditions, can prevent crystal point problem and opaque problem at 200 DEG C or more,
So that whole integraty is stronger, use intensity is higher, highly reliable.
In the present invention, substrate and pattern printing self-adhesion are formed by one using composite self-adhering film 120, in process of production not
It needs to be bonded by glue, does not need lamination technique, can effectively save cost, while improving production efficiency, save energy consumption.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
