Technical Field
The present invention relates to the field of machining and, more particularly, to a copolymer coated nonwoven abrasive belt substrate.
Background
Coated abrasives are commonly used mechanical grinding and polishing materials, also commonly referred to as coated abrasives or sandpaper. The operator grinds and polishes the surface of the machine equipment by using the abrasive on the abrasive belt, and the abrasive has hard edges and corners and can make the surface of the equipment smooth and clean during grinding. The abrasive belt mainly comprises base cloth, a binder and an abrasive material. The base cloth is a carrier of the adhesive and the abrasive and is also a support body in the grinding process, so the base cloth has the advantages of super-strong tensile strength, excellent flexibility and small extensibility. The binder serves to adhere the abrasive, which has a rough and sharp surface, to the base cloth.
At present, common abrasive belt base cloth in domestic market is mostly cotton-containing base cloth, the impurity content of the cotton-containing base cloth is more, the mass of the unit area of the base cloth is overweight, and some materials are planted with sand through static to be attached with abrasive materials, and the inflammability is larger. In addition, the existing abrasive belt base cloth is generally low in rigidity, poor in wear resistance and short in service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the aforesaid problem, provide a non-weaving abrasive band base cloth of coating copolymer to solve abrasive band base cloth unit area quality and heavily, the not high scheduling problem of base cloth rigidity.
The technical scheme of the utility model is that:
the utility model provides a non-woven abrasive belt base cloth coated with copolymer, which comprises a spun-bonded non-woven cloth layer and a polyurethane copolymer layer, wherein the polyurethane copolymer layer is arranged on the upper surface and the lower surface of the spun-bonded non-woven cloth layer; the polyurethane copolymer layer is a phenol starch resin layer, and the thickness ratio of the phenol starch resin layers arranged on the upper layer and the lower layer of the spun-bonded non-woven fabric layer is 5: 6; the spun-bonded non-woven fabric layer is internally provided with a gap.
The preferred weight ratio of the phenolic starch resin layers disposed on the upper and lower layers of the spunbond nonwoven layer was 5: 6.
Preferably, the weight of the spunbonded nonwoven layer is 50 to 70g/m 2 。
The thickness of the nonwoven coated base fabric coated with the copolymer is preferably 0.2 to 0.5 mm.
Preferably, the void structure arranged in the spun-bonded non-woven fabric layer is immersed and filled by the polyurethane copolymer layer, so that the rigidity and the strength of the non-woven abrasive belt base fabric can be enhanced.
The thicknesses of the phenol starch resin layers of the upper layer and the lower layer are preferably 0.1mm and 0.12mm, respectively.
Preferably, the spunbond nonwoven layer 1 is a network structure in the form of filaments.
The utility model has the advantages that:
the non-woven abrasive belt base cloth coated with the copolymer of the utility model adopts the spun-bonded non-woven cloth layer which is made by mixing 3 to 5 weight percent of flame-retardant master batch into the conventional polyester slice, so that the base cloth has the flame-retardant function; and then through processes of drying, melting, screw extrusion, metering, spinning, drafting, yarn dividing and the like, the yarn is woven on the conveying belt in a web forming manner, and the yarn has light weight per unit area and excellent rigidity and strength.
The utility model discloses a polyurethane copolymer be phenol starch resin layer, for nontoxic material, the environmental protection is durable, and reduction in production pollutes, saves the cost. The utility model discloses set up the phenol starch resin layer of the upper and lower floor of certain thickness proportion, can reach the requirement of low gram weight, it is convenient to use satisfying the weight reduction under the condition of abrasive band base cloth operation requirement. And the inside of the spun-bonded non-woven fabric layer is provided with gaps, and the copolymer can permeate into the gaps of the spun-bonded non-woven fabric layer, so that the rigidity and the strength of the abrasive belt base fabric are enhanced, and the excellent durability is generated. Further, the weight per unit area and the thickness of the spunbond nonwoven layer can be adjusted as desired.
Other features and advantages of the present invention will be described in detail in the detailed description which follows.
