AI Technical Summary

Benefits of technology

This technology uses both types of fibers from different sources like timbers that are already available at home without requiring extra steps such as purchasing them separately. By doing this, we have improved efficiency compared with traditional methods where they were treated differently based solely upon their properties. Additionally, when applied directly into plastic products made through polymer production processes, these techniques help create more flexible structures while reducing costs associated therewith.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency of producing useful biopolymers like natural rubbers without consuming any extra agents. Natural rubbiosources include plants grown throughout North America including China, Brazil, India, Turkey, Thailand, Indonesia, Philippines, Taiwan, New Zealand, United States, Canada, France, Poland, Germany, Italy, Greece, Peru, Chile, Alaska, California, USA, Korea, Southeast Asia, South Africa, Middle East, Central African countries, Grassland Plants, Walnut Tree Fibre Materials, Hemlock Bands® made of vegetative residues called seeds, and Humilax™ prepared by mixing pulverized wooden waste together with formaldehyde solution. These methods involve multiple steps involving drying, milling, grinding, homogenizing, forming slurry, and then subjecting it to pyrocondening. However, each step requires specific types of ingredients and extreme temperatures, leading to low yields due to energy costs. Additionally, existing processes require long periods of time and consume significant amounts of equipment.

Embodiment 1

[0033] Add 100g of 1,2-ethanediol, 4g of phenol, and 3g of sulfuric acid into the reactor, stir evenly, raise the temperature to 120°C, add 8g of crushed and dried wheat straw, and react for 40min, cool the reaction system with ice, and Discharge. A brown-black viscous liquid was obtained with a hydroxyl value of 460 mg KOH / g and a viscosity of 250 mPa.s.

Embodiment 2

[0035] Add 100g of glycerin, 6g of phenol, and 5g of hydrochloric acid into the reactor, stir evenly, raise the temperature to 140°C, add 17g of crushed and dried bagasse, react for 70min, cool the reaction system with ice, and discharge. A brownish black viscous liquid was obtained. Its hydroxyl value is 340 mg KOH / g, and its viscosity is 430 mPa.s.

Embodiment 3

[0037] Add 100g of 1,2-ethanediol and 5g of sulfuric acid into the reactor, stir evenly, raise the temperature to 140°C, add 17g of crushed and dry bagasse, react for 70min, cool the reaction system with ice, and discharge. A brownish black viscous liquid was obtained. Its hydroxyl value is 355 mgKOH / g, and its viscosity is 330 mPa.s.

Abstract

The invention refers to a kind of plant fibre liquefied and the manufacturing method, and the usage. It is made up by mixing 100 shares of polyatomic alcohol, 0-12 shares of phenol, 1-15 acid and heating them to 110-160deg.C, then adds in dried and crushed plant fibre material about 5-40 shares, reacts for 20-150 minutes, then cools them with ice. The product can be used to produce polyurethane foaming material. The plant fibre liquefied material not only can be lumber fibre material, but also can use other plant fibre material, it upgrades the use of material other than lumber resources, it reduces the consumption of chemical agent, the other hand, it can improve the flexibility of high polyurethane.
