In order to achieve the purpose, the invention adopts the following technical scheme:
a quantitative dosing capsule with a water treatment function is provided with a capsule made of a water-soluble film, a closed cavity is formed in the capsule, and a composition with the water treatment function is arranged in the closed cavity and comprises 16-60% of a metal sealing agent and 25-75% of water in percentage by weight; wherein the metal blocking agent is water-soluble polycarboxylic acid or salt thereof, or polyaspartic acid or salt thereof, or polyacrylamide, or a mixture of at least two of the foregoing.
Preferably, the metal blocking agent is an acrylic acid homopolymer and salts thereof, or acrylic acid and maleic acid copolymer and salts thereof, or polyacrylamide, or polyaspartic acid and salts thereof, or a mixture of at least two of them.
Further, the weight average molecular weight of the metal sealing agent is 1000-300000.
Alternatively, the composition further comprises an alcoholic solvent comprising ethanol, propylene glycol, glycerol, dipropylene glycol, polyethylene glycol, polypropylene glycol, or a mixture of at least two thereof.
Further, the alcohol solvent is ethanol or glycerol.
Alternatively, the composition further comprises a broad spectrum antimicrobial agent.
Alternatively, the composition further comprises a wetting or solubilizing agent.
Further, the wetting agent is a non-ionic wetting agent comprising an alkyl ethoxy polymer, an alkyl ethoxy propoxy copolymer, an alkyl glycoside, or a mixture of at least two thereof.
Alternatively, the composition further comprises a small molecule metal blocking agent.
Preferably, the water-soluble film contains a polyvinyl alcohol resin.
The invention adopts the packaging form of quantitatively putting the capsules, so that the chance of contact between a consumer and chemicals can be reduced, and the health of the consumer is guaranteed; in addition, the step of metering chemicals by consumers can be omitted, and the use is simpler and more convenient; in addition, the composition is liquid, can be quickly mixed with water, does not need to wait for dissolution, does not generate heat, and is safer to use.
Detailed Description
The invention relates to a quantitative dosing capsule with a water treatment function, which is provided with a capsule made of a water-soluble film, wherein a closed cavity is formed in the capsule, and a composition with the water treatment function is arranged in the closed cavity and comprises 16-60% of a metal sealing agent and 25-75% of water by weight percent; wherein the metal blocking agent is water-soluble polycarboxylic acid or salt thereof, or polyaspartic acid or salt thereof, or polyacrylamide, or a mixture of at least two of the foregoing.
The metal blocking agent is preferably acrylic acid homopolymer and its salt, or acrylic acid and maleic acid copolymer and its salt, or polyacrylamide, polyaspartic acid and its salt, or their mixture of at least two. In addition, if the weight average molecular weight of the metal blocking agent is less than 1000, the solution is very soluble through the water-soluble film; when the weight average molecular weight of the metal blocking agent is higher than 300000, the solubility of the metal blocking agent decreases, and therefore, the weight average molecular weight of the metal blocking agent is preferably in the range of 1000 to 300000.
In addition, the composition can be added with an alcohol solvent besides water, wherein the alcohol solvent comprises ethanol, propylene glycol, glycerol, dipropylene glycol, polyethylene glycol, polypropylene glycol or a mixture of at least two of the ethanol, the propylene glycol, the glycerol and the propylene glycol are preferred options.
In addition, the composition can also be added with a broad-spectrum bactericide, so that the composition has a sterilization function and the water quality treatment capability of the composition is further improved. Common broad spectrum fungicides can be Parachlorometaxylenol (PCMX), sodium hypochlorite, triclosan, hydrogen peroxide, phenoxyethanol, bronopol (Bronopol), sodium benzoate, isothiazolinones and their derivatives, C8-C18 alkyldimethylbenzylammonium salts, 1-C8-C18 alkylpyridinium halides, and nanosilver, or a mixture of at least two of these.
In addition, the composition can also be added with a wetting agent or a solubilizer, and the function of the composition is that on one hand, the solubility of the bactericide in the liquid can be further improved under the condition of adding the bactericide; another aspect is to provide wettability to the body of water where needed. The wetting agent is preferably an uncharged non-ionic wetting agent, such as an alkyl ethoxy polymer, an alkyl ethoxy propoxy copolymer, an alkyl glycoside, or a mixture of at least two thereof, more preferably an alkyl glycoside.
In addition, on the premise of ensuring that the composition solution does not precipitate under the daily temperature and humidity, a micromolecular metal sealing agent can be added according to the requirement to enhance the metal ion sealing and dispersing capacity. Common small molecule metal blocking agents may be citric acid or salts, gluconic acid or salts, ethylenediaminetetraacetic acid or salts (EDTA), nitrilotriacetic acid or salts (NTA), diethylenetriaminepentaacetic acid or salts (DTPA), hydroxyethylphosphonic acid or salts, hydroxyethylidene diphosphonic acid or salts (HEDP), glucoheptonic acid or salts, glutamic diacetic acid or salts (GLDA), methylglycine diacetic acid or salts (MGDA), and the like, or mixtures thereof may be added.
The water-soluble film of the present invention may be a water-soluble polymer film which is conventionally used, and preferably a polymer film containing a polyvinyl alcohol resin.
The quantitative capsule feeding method can be used for encapsulating the capsule by adopting the conventional heat sealing method, and is not described again.
The compression resistance is an important index for evaluating the storage stability of the capsule, and the instant compression resistance of the quantitatively put capsule is not lower than 300N after the capsule is manufactured, so that the capsule has enough compression resistance when being in a compressed state in the storage and transportation process, and is ensured not to crack before being reused.
The test method of the compression resistance is as follows: a pressure tester is used to place a bare bead under increased pressure at a displacement rate ranging from 200 to 250 mm/min until 300N is reached or the bare bead ruptures to release its contents, and the maximum pressure value is recorded as the pressure resistance of the capsule. In order to prevent the naked beads from being splashed by the internal liquid to pollute the instrument when the naked beads are broken by force, the naked beads are generally placed in a plastic bag with small air holes for pressure test.

Test of Metal ion sealing Capacity
The degree of metal ion occlusion is expressed as the change in the concentration of free Fe ions in water. The concentration of free Fe ions can be detected by a phenanthroline spectrophotometry, and the method can be referred to in section 2.2 of GB/T5750.6-2006 Drinking Water Standard test method Metal indexes.
The specific water treatment method comprises the following steps: taking a water sample to be treated rich in Fe ions, taking 5L of a water sample, putting a capsule coated with 10g of metal sealant solution into water, stirring for 3min by using a glass rod, standing for 30min, and taking the water sample for detection. (no capsules were added for blank test). The test results were as follows:
from the above test results, it can be seen that the present invention can effectively reduce the concentration of free iron ions in water. In addition, according to the principle of blocking or chelating by the metal blocking agent, the invention can also reduce the concentration of free metal ions such as aluminum ions, calcium ions, magnesium ions, copper ions, zinc ions, lead ions and the like in water.
Taking example 10 as an example, water samples containing different free metal ions are tested, and the test method of each ion can be referred to "GB/T5750 Standard test method for Drinking Water", and the results are as follows:
