Non-woven fabrics contains the surface of PUR by thermal composite machine hot pressing by nonwoven heating, and temperature is less than or equal to 120 DEG C, then with wall paper
Bonding.
Beneficial effects of the present invention are as follows：
1st, nonwoven surface is covered with PUR, and the raw material of PUR is EVA particles, changes the hot glue work of traditional liquid glue
Skill, time saving and energy saving, free from extraneous odour, the feature of environmental protection is improved, while EVA particles include ethylene-vinyl acetate EVA50-60 parts, modification
EVA30-60 parts, tackifying resin 15-20 parts, plasticizer 5-10 parts, function additive 0.1-5 parts, ensure that PUR is fixed by covering
Nonwoven surface can be covered in after type, the viscosity of PUR is maintained at a moderate scope, prevents that PUR viscosity is too low,
Easily oozed non-woven fabrics and penetrate into wall paper, and reduced the cementability of non-woven fabrics and wall paper, and prevent that PUR viscosity is too high, consolidation is filled
Point, need to heat the long period when Nian Jie with wall paper, therefore, the content of the EVA particles of the formula ensures that PUR is placed in liquid
And 1 boundary's point of solid, PUR is maintained at a moderate viscosity when being pasted with non-woven fabrics, be easy to post storage to receive
Hide.
2nd, tackifying resin is terpene resin or Petropols, and terpene resin or Petropols have low smell, high rigidity, height
The advantages of adhesive force, inoxidizability and thermostabilization are good.
3rd, the non-woven fabrics craft of coating hot-melt adhesive, processing step is simple, using low-temperature hot melt adhesive membrane production equipment, by low
Warm Extrusion, cover sizing, the concrete technology step of cooling winding, make PUR kept when being pasted with non-woven fabrics one it is moderate
Viscosity, while change the production stage of conventional fused case coating process, the tape casting is extruded using low temperature, it is wide to expand hot melt adhesive film
Width, ensure hot melt adhesive film wide cut more than 2 meters, low temperature of the invention extrusion the tape casting passes through motor driven screw rod, screw rod outer surface
Helicoidal structure the raw material that raw material enters in bucket is promoted toward extruder direction, hot melt adhesive film raw material is by the cooling tube in screw rod
A is cooled down, and hot melt adhesive film raw material is with the rotation of screw rod, and it is higher to be more proximate to extruder position temperature, hot melt adhesive film melting sources
Into aneroid flow regime, extruded to non-woven fabrics by extruder, then covered by setting roll sizing, then successively through supercooling
But wind, complete the whole production technology of hot melt adhesive film, improve the stability of hot melt adhesive film product and the essence of the thickness uniformity
Degree.
4th, cooling tube a length is the 10%-20% of the length of screw rod, and cooling tube a length is unsuitable long, cooling tube a's
Length is long, then hot melt adhesive film raw material can not be in flow regime, just efficiently quickly can not be extruded out of extruder, as cooling tube a
During the too short a even without cooling tube of length, hot melt adhesive film gradually increases with the rotation temperature of screw rod, and hot melt adhesive film raw material is from squeezing
Go out when extruding in machine because temperature is too high into liquid condition, be during the covering of non-woven fabrics, no legal type, and be easily sticked to
On each roller, cause whole production equipment can not normal operation work, therefore, cooling tube a length is the length of screw rod
10%-20% is optimal design length.
5th, connect rod and play a part of tensioning between unreeling structure and sizing cover mechanism, improve the steady of non-woven fabrics
Property, prevent from crumpling, improve planarization, the precision of the thickness uniformity that hot melt adhesive film pastes.
6th, the hot glue technique of a kind of non-woven fabrics of coating hot-melt adhesive and wall paper, the non-woven fabrics for being covered with PUR is contained into heat
By thermal composite machine hot pressing by nonwoven heating, temperature is less than or equal to 120 DEG C, then is bonded with wall paper, prevents temperature on the surface of melten gel
Height is spent, PUR is liquefied and is easily overflowed from non-woven fabrics, avoids the phenomenon for causing degumming.
