Description

1. Designation of the InventionBiodegradable water resistant adhesive for versatile applications2. Technical FieldThe present invention relates to a biodegradable adhesive based on natural raw materials and suitable for various applications. The adhesive is distinguished by a high adhesive strength, water resistance and environmental friendliness.3. Prior ArtConventional adhesives are often made from synthetic polymers which are not biodegradable and may contain microplasty. These adhesives have several disadvantages:• Environmentally hazardous: Many contain solvents or plastics which cannot be degraded.• Non-water resistant: Biological adhesives often lose their adhesive power in the case of moisture.• Brittle on aging: Many natural adhesives lose their elasticity after a long time.4. Object of the InventionThe object of the invention is to provide a durable, water-resistant adhesive which consists exclusively of biodegradable materials and at the same time has a high adhesive strength and flexibility.5. Solution of the InventionThe adhesive of the invention is based on a mixture of natural binders, waxes and resins which in combination form a strong, elastic and water-resistant adhesive bond.5.1 Composition of the adhesiveThe adhesive contains the following components: 1. gum arabic (25%) Natural binder providing strong adhesion◯ Increases the Flexibility of the Adhesive2. Bee wax (30%) water repellency improves suppleness◯ supports long-term stability3. Colophony (rosin) (15%)◯ Strength◯ Increase Water Resistance4. Corn starch (10%)◯ stabilizes the paste and improves consistency◯ Increases the Adhesive Force5. Vegetable oil (5%)◯ prevents brittleness and provides elasticity6. Water (5-7%)◯ Is used for dissolution of the gum arabic5.2 Production Method1. Preparation of Gum Arabic Mix gum arabic with hot water until a viscous paste is formed.2. melting of the wax components Melt the beeswax and rosin in a water bath at low temperature.3. Blending of dry components Mix corn starch with the gum arabic mixture.4. Joining the Components◯ Add and stir the molten wax-resin mixture stepwise.5. Adding the vegetable oil vegetable oil to obtain flexibility.6. Cool down◯ Let the mass cool until it reaches the desired consistency.5.3 Properties of the AdhesiveHigh water resistance: the wax and resin content maintains the adhesive strength even in the case of moisture.Strong adhesion: gum arabic and colophony ensure reliable adhesive action. Elasticity & Longevity: The mixture of vegetable oil and corn starch leaves the adhesive supple.Environmentally Friendly & Biodegradable: All ingredients are completely compostable.6. Advantages of the Invention• 100% biodegradable - Non-synthetic polymers or microplasty• Water-resistant - Suitable for moist applications• High Adhesive Force - Adheres reliably to different surfaces• Flexible consistency - Prevents brittleness or hardening over time• Simple Production - Can be produced in a large scale in an environmentally friendly manner
