Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of paper towel production and processing, and in particular relates to a treatment agent for manufacturing soft paper towels and a preparation method thereof. Background Art
[0002] As people's demand for daily paper increases, the quality standards of paper are also constantly improving, especially the demand for its softness is more urgent. The fiber molecular chain of paper contains multiple hydroxyl groups, forming linear macromolecules, which makes the paper have a certain strength and rigidity because the intermolecular forces and bonds are very strong. Although mechanical methods such as adding additives and beating can disperse fiber molecules, reduce crystallinity, and increase softness to a certain extent, this cannot fundamentally solve the problem of paper softness.
[0003] To truly improve the softness of paper, the interaction between fiber molecules must be reduced to enable the chain segments and molecular chains to move freely. Most paper softeners contain C 16 The above surfactants with hydrophobic groups, under appropriate process conditions, adhere to the surface of the fiber and form a hydrophobic film that wraps the fiber, thereby improving the softness of the paper; reducing the friction of the paper on the skin, increasing the smoothness and delicate feeling of the paper; thus obtaining a smooth and soft feel. This method can make the paper softer, thus meeting people's needs for comfort in use. The preparation of paper softeners through scientific formulas and process improvements can effectively improve the softness of the paper, making it more comfortable and convenient during use.
[0004] At present, paper softeners mainly include silicone polymer softeners, wax latex softeners, metal complex softeners, etc. Although silicone polymer softeners have good softening effects, the raw material price is relatively high. Wax latex softeners are mainly suitable for wax paper and waterproof paper, but they have some effect on the water absorption performance of paper. Metal complexes are mainly metals such as chromium and zirconium, which may cause allergic reactions and are therefore not suitable for use on household paper. In industrial production, people need a low-cost, low-allergenic soft paper towel treatment agent that can make paper soft and easy to absorb water, to effectively improve the feel of paper, reduce friction on the skin, and at the same time enhance the smoothness and delicateness of paper, thereby improving the overall user experience. Summary of the invention
[0005] The purpose of the present invention is to provide a treatment agent for manufacturing soft tissue and a preparation method thereof, in particular to provide a treatment agent for manufacturing soft tissue, which mainly comprises a microemulsion formed by emulsifying amino silicone oil with a composite emulsifier.
[0006] The specific technical solutions are as follows: A treatment agent for manufacturing soft tissue paper, which comprises, by weight, 300-400 parts of water, 80-100 parts of amino silicone oil, 0.1-0.5 parts of acidity regulator, 33-55 parts of nonionic emulsifier, 8-10 parts of hexadecyltrimethylammonium bromide, 3-5 parts of alkylbenzenetrimethylammonium chloride and 2-4 parts of sodium benzoate; the nonionic emulsifier comprises: 18-22 parts of oleyl alcohol polyether and 25-32 parts of alkylphenol polyoxyethylene ether, and the preparation method thereof comprises: mixing 18-22 parts of oleyl alcohol polyether and 25-32 parts of alkylphenol polyoxyethylene ether at 25-35°C and stirring at 600-800°C. The mixture is stirred at a speed of r / min for 20 to 40 minutes to form a uniform non-ionic emulsifier; the oleth may be a combination of one or more of oleth-20 and cetyl oleth-10; the alkylphenol polyoxyethylene ether may be a combination of one or more of nonylphenol polyoxyethylene ether and octylphenol polyoxyethylene ether.
[0007] In some embodiments, the acidity regulator may be a combination of one or more of acetic acid, citric acid, lactic acid and phosphoric acid.
[0008] In some embodiments, the method for preparing the treating agent for making soft tissues comprises the following steps: Preparation of S1 emulsifier: Add 33-55 parts of nonionic emulsifier and 8-10 parts of hexadecyltrimethylammonium bromide into a multifunctional reactor, stir at a rate of 1300-1500 r / min, mix and stir at 50-60°C for 20-30 minutes to obtain a composite emulsifier.
[0009] Preparation of S2 microemulsion: Continue to add 80-100 parts of amino silicone oil and 0.05-0.3 parts of acidity regulator to the multifunctional reactor in step S1, with a stirring rate of 1000-1200 r / min, mix and stir at 50-60°C for 20-30 minutes, naturally cool to 35-45°C, slowly add 200-300 parts of water, and stir at a rate of 1000-1200 r / min for 75-80 minutes.
[0010] S3 antiseptic and antibacterial: add 3 to 5 parts of alkylbenzenetrimethylammonium chloride and 2 to 4 parts of sodium benzoate to the multifunctional reactor in step S2, continue stirring at a rate of 1000 to 1200 r / min for 15 to 20 minutes, add 0.05 to 0.2 parts of acidity regulator to adjust the pH value.
[0011] S4 dilution and cooling: add 100 to 200 parts of water to step S3 to dilute the mixture, continue stirring at a rate of 1000 to 1200 r / min and gradually cool to 25 to 30° C. to obtain a soft tissue treatment agent.
[0012] In some embodiments, when adding water in step S2 and step S4, water is added at a rate of 1 to 5 g per minute under stirring until the viscosity of the emulsion decreases to 5 to 8 mPa·s.
[0013] In some embodiments, when the acidity regulator is added in step S2, the pH value of the mixed solution should be measured with a pH meter first, and then the pH value should be adjusted to 4-6 with the acidity regulator.
[0014] This reaction has the following advantages: (1) Environmental friendliness: Nonionic emulsifiers are more environmentally friendly. They have less impact on the environment and have good biodegradability.
[0015] (2) Hypoallergenicity: Traditional softeners may contain some ingredients that may cause skin allergies, such as certain cationic surfactants. Softeners prepared by emulsifying amino silicone oil with a composite emulsifier are usually milder, less irritating to the skin, and suitable for sensitive skin.
[0016] (3) Better softening effect: The composite emulsifier can more effectively combine the softener ingredients with the paper fibers, thus providing a better softening effect. This means that the treated paper is softer, smoother and has a better touch.
[0017] (4) Antibacterial and antiseptic properties: Sodium benzoate and alkylbenzenetrimethylammonium chloride can effectively prevent the growth of fungi and kill bacteria, thereby preventing the product from being contaminated and corrupted by bacteria and fungi, thereby maintaining the hygiene and quality of the product.
