Abstract

The lubricant layer is the layer that comes in contact with the skin. Formed by making polymers that have gelatinous properties when wet, adhere to rubber objects. (For example, a surgeon's glove). serfactant cat ionic model which can eliminate bacteria It is preferable to have 6-18 carbon, alkyl or alkyl groups (for example, normal-hexadecil groups) or fatty acid-containing fatty acids. long chain structure This is to make the level of handsome. The slipperiness of such layers is better when used on damp skin. This wet jelly-like polymer is commonly used. is the copolymer of 2-hydroxyethyl methacrylate (HEMA) with methacryic acid (MAA) or with 2-ethylhexylmethacrylate (EHA) or with both MAA and EHA. lemurs with similar properties The agar when wet such water helps to improve the lubrication level when Use on dry skin And when used for such purposes, there is no need to go through the process with serfactants. or compounds To improve the level of lubrication better in the case of use with wet skin.

Claims (2)

1. Items made of rubber and bendable. This object has a lubricant layer made from a agar-like polymer, when wet, this layer is attached to act as a contact surface. Between the skin and the said object Features of this item Is that a serfactant or a structured fat amine is added Create a long chain into the surface for loud surface contact. Said to make the skin lubrication better when used With wet skin 2. Object according to claim 1, in which serfactant is an ionic serfactant 3. item according to claim 2, in which serfactant is substance Cat ionic type serfactant 4. Item according to claim 3, which serfactant is a substance Consists of quaternary ammonia, which contains at least one group 6-18 carbon hydrocarbons, 5. Item according to Proposition 4, in which the hydrocarbon group is attached. With the nitrogen atoms of the quaternary As part of the band Heterocyclic ring 6. Items according to claim 5, in which the heterocyclic ring is Pyridine morpholine Or Imdazoline 7. Items according to the claim 6, in which the serfactant is a normyl lauryl salt or a normal salt - setyl pyridinium or anhydrous salt Oxyethyl Heptadecylimidazoline 8. Item according to claim 4, in which the serfactant is hexadecyl trimethylammonium chloride 9. Item according to claim 1 to 8 which Polymers with you Agar-like is a copolymer of 2-hydroxyethyl methacrylate with methacrylic acid and / or with 2-ethylhexyl methacrylate The above copolymer has elements within the ABCDEF area in the attached Ternary Composition Chart 1 0. Objectives of Proposition 9, of which 2-ethylhexylocrylate Is represented by other alkylocrylates, or Containing alkyl methacrylate Same result 1 1. Items according to claim 9 in which the copolymer has an element within the PQRI area in this attached Ternary Composition Chart 1. 2. The process for the manufacture of articles according to claim 1 to 11 consists of the following steps: a) Produce rubber workpieces by immersing a suitable template into the liquid rubber; b) washing the rubber workpiece on the template in hot water; c) finishing. Smooth surface of the rubber workpiece on the template. D) Wash the workpiece surface with water or alkaline solution e) Immerse the specimen while still on the template in the hydrophilic polymer solution. And has properties like jelly when wet And stabilizer f) dry the coating by heat. To make polymers with Agar-like properties when wet are attached to the rubber. G) Bake the rubber with sulfur. And at the same time maintain the condition of the poly H) Remove the part from the template i) Put the silicon-based serfactant solution into the layer. The polymer coating with agar-like properties when wet and j) forms a coating of the substance. Sherfactant to get hot To fix the slip properties of That coating layer (12 claims, 3 pages, 1 photo)
