Problems solved by technology

The production process of this method is relatively complicated, and the mass production efficiency is relatively low. The molecular weight of the hydrophilic substances used in this method is not more than 6000, and the solubility is strong; the slow-release effect of the produced vitamin C sustained-release dropping pills is not good, and it takes about 2 weeks. , more difficult to apply to household water purification and bathroom industry

Embodiment 1

[0029] A slow-release vitamin C filter material for household water treatment, which is composed of the following ingredients by weight percentage: polyethylene glycol (molecular weight: 20,000) 72.5%, vitamin C 10%, vitamin E 5%, molecular sieve 10%, baking soda 2%, tartaric acid 0.5% %.

[0030] The preparation method of the slow-release vitamin C filter material comprises the following steps:

[0031] 1. Mix polyethylene glycol (molecular weight 20,000), vitamin C, vitamin E, molecular sieve, baking soda and tartaric acid in the drum mixer according to the proportion, put them into the screw extruder for extrusion, and then pass through the granulator Granulation, made into granular material.

[0032] 2. Dry the prepared granular material in an oven at 50° C. for 3 hours to obtain the slow-release vitamin C filter material.

[0033] Fill 150g of the slow-release vitamin C filter material in the shower filter container, control the water flow rate to 8L / min, and the initia...

Embodiment 2

[0038] A household water treatment slow-release vitamin C filter material, which is composed of the following ingredients by weight percentage: polycaprolactone 64.8%, vitamin C 20%, vitamin E 5%, diatomaceous earth 5%, azodicarbonamide 5%, tartaric acid 0.2%.

[0039] The preparation method of the slow-release vitamin C filter material comprises the following steps:

[0040] 1. After mixing polycaprolactone, vitamin C, diatomaceous earth, vitamin E, azodicarbonamide and sodium bisulfite in a drum mixer, put them into a screw extruder to extrude, and then make Granulator granulation, made into granular materials.

Abstract

The invention discloses a household water treatment filter material capable of slowly releasing vitamin C. The household water treatment filter material is prepared from the following components in percentage by weight: 50 to 95 percent of a hydrophilic organic macromolecular polymer, 1 to 20 percent of vitamin C, 0.5 to 5 percent of vitamin E, 2 to 20 percent of an inorganic porous adsorbent, 2 to 5 percent of a foaming agent and 0.1 to 0.4 percent of an antioxidant synergist. The invention further discloses a preparation method of the household water treatment filter material capable of slowly releasing vitamin C. The filter material can control the slow release speed of vitamin C and prolong the dissolving time of vitamin C.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a household water treatment slow-release vitamin C filter material and a preparation method thereof. Background technique [0002] Vitamin C, also known as L-ascorbic acid, is an essential nutrient for higher primates and a few other organisms. Vitamin C is for the formation of antibodies and collagen, tissue repair (including certain redox effects), metabolism of phenylalanine, tyrosine, and folic acid, utilization of iron and carbohydrates, synthesis of fat and protein, maintenance of immune function, hydroxyl Vitamin C and serotonin are necessary to maintain the integrity of blood vessels and promote the absorption of non-heme iron. At the same time, vitamin C also has anti-oxidation, anti-free radicals, and inhibits the formation of tyrosinase, so as to achieve the effect of whitening and lightening spots. [0003] Vitamin C is widely used clinically and is one of th...
