Definitions

  • the invention relates to a composite material formed by using boron during production of a polyurethane base material.
  • wound healing materials produced using Boron are available, which materials are obtained by adding boron to the structures such as collagen, hydrogel. Wound healing materials formed by adding Boron to a polyurethane material are not included in the state of the art.
  • the patent document no. TR 2019/12225 discloses polyurethane foam produced for hygiene.
  • the amount of boron added to the foam contains 10% borax.
  • Said patent document disclosed a composite material obtained by adding 9-35% boron compound to a polyol during polyurethane production. Therefore, the ratio of the boron compound in the composite material is provided to be 5-23%. Said patent document does not disclose the wound healing property of the composite material.
  • the patent US8147857 describes the production of a polyurethane gel as an antiseptic wound dressing.
  • the present invention relates to the use of a boron compound to enable the flexible polyurethane foam to gain wound-healing properties. Said document does not disclose the production of the polyurethane foam material.
  • the wound healing property of said polyurethane gel is not mentioned.
  • boron was added to a wide variety of materials. During this addition, boron is added to the foam by an impregnation method, but after this method, the foam loses its original property. The pores of the foam which is normally flexible, is an open cell foam and is air-permeable are closed after the boron impregnation, thus the permeability property is lost and the foam hardens. This technical problem in the state of the art needs to be overcome.
  • the object of the invention is to produce a composite material by adding boron to flexible polyurethane foam.
  • Said composite material is used in the fields such as medical, cleaning, mattress, upholstery (sofa), bras, and shoe insoles.
  • the composite material used for medical purposes is used to heal wounds.
  • the composite material formed by adding boron to the flexible polyurethane foam does not lose its flexible and air-permeable properties. Therefore, in foams which are normally flexible, are open cell foams and are air-permeable, the pores of the composite material obtained after the addition of a boron compound during the production of a base material are not closed, so the permeability is not lost and the foam does nor harden.
  • the amount of boron added to the material is important to have specific values. This value should be at least 40%.
  • Figure 1 is a schematic perspective view of a composite material according to the invention.
  • the invention relates to a composite material (1) formed by adding a boron compound (1.2) to a base material (1.1). Said composite material (1) will be used especially for medical purposes and has a wound healing property.
  • the composite material (1) of the invention includes a base material (1.1) and a boron compound (1.2) added to said base material (1.1) at a predetermined ratio.
  • Said base material (2) is flexible and is, but not limited to, a polyurethane material in a preferred embodiment of the invention.
  • the polyurethane material is preferably, but not limited to, a foam.
  • the boron compound (1.2) is added to the base material (1.1) during the production of the base material (1.1). Boron Compound (1.2) is not impregnated to Polyurethane base materials (1.1) in the state of the art with the invention. The boron compound (1.2) is added to the base material (1.1) during the production of the base material ( 1.1 ), so that a composite material (1) is obtained.
  • the pores of the base material (1.1) are formed during the production.
  • the particles of boron compound (1.2) incorporated in the production system are positioned around the pores. Therefore, the boron compound (1.2) does not cause any blockage in the pores.
  • the boron compound (1.1) is present in powder form, and the boron compound (1.2) is dispersed in the polyol and added to the base material (1.1).
  • the ratio of the boron compound (1.2) added to the base material (1.1) is 40% to 45%.
  • the composite material (1) of the invention has wound healing properties as well as antibacterial properties. It may also be used in all areas that require hygiene.
  • the mixture of polyol and boron compound (1.2) of equal amounts during production of polyurethane base material (1.1) is added to the production system.
  • the ratio of the boron compound (1.2) in the composite material (1) is allowed to be at least 40% by adding the mixture obtained with the addition of boron compound (1.2) of 50% to the polyol to the base material (1.1).
  • the pores are not blocked and the polyurethane base material (1.1) is not lost, as a result it does not harden, as the boron compound (1.2) is added to the system at this ratio during the production of the polyurethane base material (1.1).
  • Table 1 provides the content of the composite material (1) and the percentages by weight of the content. Table 1. Chemical content of the composite material (1) and the percentages by weight therefor
