Abstract
The present invention discloses a waterproof agent for textile products with mildew proof, sterilization and aeration. Terpene resin salt is formed by the reaction of terpene resin, alkali and wax, and waterrepellent terpene resin acid is formed by the reaction of the terpene resin salt and amphiprotic compounds under acid condition. The waterrepellent terpene resin acid and a certain amount of antimildew bactericide are adsorbed on the textile fiber, the reaction mechanism is reasonable, and the present invention overcomes the defects of pollution and high cost because of isopropyl alcohol as solvent. The present invention has the advantages of simple manufacturing process, stable performance and easily manipulative quality, and conforms to the state food sanitation requirement; the present invention can widely be applied to packing clothing, grain, cotton, medicine, tobacco, food, etc. and armored fabric, such as an awning and a cover. Because of easily gainable raw materials and low cost, the present invention can be used for civil household.
Description
The invention relates to a waterproof agent for textile fiber products.
Due to the development of social production and the needs of human life, preparations and methods for treating textile fiber products to simultaneously have the functions of mildew resistance, sterilization, ventilation and water resistance have been discovered. The existing water-proofing agents for industrial canvas and various cloth-based clothing fabrics generally contain metal chromium compounds, silicone or silicon-fluorine series compounds, can generate certain industrial pollution and certain harm to human bodies, and are easy to generate mildew and bacteria because of poor air permeability.
The prior art at home and abroad, such as several fabric waterproof agents proposed in the technical data of foreign fabric finishing compiled by the academy of textile sciences of Shanghai (published by 1972.9) and the fabric finishing agent provided by the Chinese patent application No. 89101013.0, all have the disadvantages described above, and do not meet the food hygiene standards in use. The special waterproof agent for grain and cotton containers, which is described in Chinese patent application No. 92102992.6, still contains silicone, and the component B generates inorganic salt, so the operation principle is not reasonable, the process is complex, and the cost is high.
The invention aims to provide a textile fiber product waterproof agent with the functions of mildew resistance, sterilization, ventilation, water resistance and the like, which has the advantages of easily obtained raw materials, reasonable synthesis process, simple preparation and easy quality control and conforms to the national food sanitation standard.
The waterproof agent of the invention is also composed of A, B two-component preparation, and the invention is characterized in that the working principle of A, B two-component combination can be expressed by the following four chemical reaction formulas:
(1)
(3)
(4)
wherein: m1Alkali metals such as sodium, potassium, etc.; m2Is an amphoteric metal such as aluminum.
The reaction products are water repellent. Meanwhile, after other auxiliary agents are added, the adhesive has strong adsorption force and can be well adsorbed on textile fibers to play a waterproof role.
In the waterproof agent, A, B two preparations are both aqueous agents.
The A component preparation consists of the following raw materials in parts by weight: terpene resin 10, alkali 1, candle wax 5, long-chain fatty acid 6, gelatin 5 and forming auxiliary agent 6. The preparation process includes adding terpene resin 10 weight portions into water 30 weight portions, adding alkali, and heating to over 80 deg.c for dissolving. Adding 5 parts of gelatin, 5 parts of candle wax and 6 parts of long-chain fatty acid while stirring until the reaction is finished, and adding a forming aid (NaCO) when the temperature is reduced to 60 DEG C3) Stirring for reaction for 15 min, and cooling. The long chain fat can adopt 16-carbon or 18-carbon or 20-carbon fatty acid.
The component B is prepared from the following raw materials in parts by weight: amphoteric compound 1, weak acid 0.5 and mildew-proof bactericide 0.0001. The preparation method comprises the following steps: taking amphoteric compound Al2(SO4)3(or alum) 1 portion is dissolved in 40 portions of water, 0.5 portion of weak acid (boric acid or cerotic acid) is added, then 0.0001 portion of mildew-proof bactericide is added, and the mixture is heated and boiled for 10 minutes. The component B can also be prepared in situ, and the dosage of the component B is calculated by the dosage of the component A according to a reaction equation described in the working principle.
The mildew-proof bactericide adopted by the invention is molinate.
When the waterproof agent for the mildew-proof, bactericidal and breathable textile products is used, textile fibers of different materials are soaked in the preparation of the component A and then the preparation of the component B respectively at the temperature of 60-100 ℃, and then the textile fibers are dried. The action mechanism is that the terpene resin salt generated by the component A preparation reacts with the acid generated by the amphoteric compound in the component B preparation under the acidic condition to generate terpene resin acid, and the organic acid is easily adsorbed by the surface of the fabric fiber to form a waterproof film.
The fabrics of cotton, hemp, chemical fiber, blended fabric, woolen cloth and silk treated by the waterproof agent have the advantages of unchanged color, unchanged quality and unchangedair permeability. And the strength of the fabric is improved, the fabric is soft without generating rigidity, the fabric is not cracked after being folded for many times, and the fabric is not leaked after being soaked in rainwater for 24 hours. It can be used as various waterproof clothing fabrics, waterproof and moistureproof cover cloth for instruments and equipment and various special industries, such as ordnance rainproof cover cloth. Meanwhile, the waterproof material can be widely used as a waterproof material for packaging fabrics for mildew prevention, sterilization and water prevention of materials such as various foods, medicines, tobaccos, grains, cottons and the like. The invention has the advantages of low cost, easy manufacture, convenient use, no pollution and no harmful substances.
Example 1 preparation of component A. Heating terpene resin 10Kg and industrial caustic soda 1Kg in hot water 30Kg, stirring, maintaining at 85 deg.C, continuously stirring, heating to boil after solid completely dissolves, adding gelatin 5Kg, candle wax 5Kg and acacia (long chain fatty acid) 6Kg while stirring, stopping heating after solid completely dissolves, stirring, cooling to 60 deg.C, adding 6Kg NaCO3And stirring for reaction for 15 minutes and then standing for later use.
And preparing the component B. Taking Al2(SO4)3Adding 0.5Kg of boric acid 1Kg into 40Kg of hot water, stirring and dissolving, adding 0.1g of molinate, continuously stirring and boiling for 10 minutes.
The preparation method is suitable for treating relatively thick fabric such as canvas, and comprises soaking the fabric in 80 deg.C component A preparation, soaking in boiling component B preparation, and oven drying.
Example 2 preparation of component A. Heating terpene resin 10Kg and edible alkali 1Kg in hot water 30Kg, stirring, maintaining the temperature at 82 deg.C, continuously stirring, continuously heating to boil after solid completely dissolves, adding gelatin 5Kg, candle wax 5Kg and gum (long chain fatty acid) 6Kg while stirring, stopping heating after solid completely dissolves, continuously stirring until the temperature drops to 60 deg.C, adding 6Kg NaCO3And stirring for reaction for 15 minutes and then standing for later use.
And preparing the component B. Dissolving Alumen 1Kg acetic acid 0.5Kg in hot water 40Kg, adding molinate 0.1g, stirring and boiling for 10 min.
The preparation is suitable for treating thinner fabrics, and is prepared by soaking fabrics in the A component preparation at 70 ℃, then soaking in the boiled B component preparation, and finally drying.
