Description
Technical Field
The invention relates to a preparation method of a temperature-adjusting article, in particular to a method for intelligently processing an article by using micro-particles.
Background
Intelligent microparticle (GERM) is a particle prepared by phase change energy storage technology. The phase change energy storage technology is a novel environment-friendly energy-saving technology for absorbing, storing and releasing energy by using a phase change material, can solve the contradiction of unbalance of energy supply in time and space, is an important technology for improving energy utilization efficiency and protecting the environment, and has important significance for relieving the energy problem which is increasingly nervous. The phase change material has three states of solid, liquid and gas, and solid-gas and liquid-gas phase change is accompanied by a large amount of gas due to high-temperature sublimation in solid-solid phase change, so that the development and utilization of the solid-liquid phase change material (such as long-chain alkane, paraffin, polyethylene glycol, fatty acid ester and the like) have the best application prospect. Although the phase change process of the solid-liquid phase change material is an isothermal or approximately isothermal process, the phase change process is accompanied with the absorption or release of energy, the temperature of a system or an environment can be regulated and controlled, the functions of heat energy storage and temperature regulation are realized, and the solid-liquid phase change material has the advantages of high energy storage density, small volume of a heat storage container, high heat efficiency, constant heat absorption and release temperature and the like.
With the continuous development of science and technology, people have higher standards for the requirements of textiles, wood products and metal products, and the requirements of people on the comfort are met by adjusting the environmental temperature.
Taking textile as an example, multifunctional textiles have been produced, wherein the development and application of the phase change heat storage temperature adjusting fiber and the textile thereof are widely concerned, and the phase change heat storage temperature adjusting fiber can adjust the temperature of clothes and the environment by absorbing, storing and releasing heat energy, reduce the change of skin temperature and improve the wearing comfort of human bodies. If the outside temperature is increased, the energy for increasing the molecular motion of the phase-change material is provided, and the temperature of the clothes and the surrounding microclimate is gradually increased until the melting point of the phase-change material is reached. When the external temperature rises to the melting point of the phase-change material, the phase-change material is gradually changed from solid to liquid, so that the external heat can be absorbed and stored as latent heat, and the clothes and the surrounding microclimate are kept unchanged at the phase-change temperature point; when the outside temperature is reduced, the phase change material is gradually solidified and releases latent heat, the temperature of the clothes and the surrounding microclimate is kept constant, and the phase change material is widely applied to the aspects of textile clothes, sporty clothes, physical therapy and the like.
The phase-change material for processing the fabric at present generally adopts a layer of wall material to coat a phase-change core material, and only performs phase-change energy storage at one temperature. If the phase-change material with higher phase-change temperature is adopted, the phase-change material can not generate phase change at lower temperature and can not change the temperature. If the phase-change material with lower phase-change temperature is used, the effect of reducing the temperature cannot be well achieved at higher temperature due to the limitation of the phase-change material at high temperature. Therefore, the existing phase change capsules can only adapt to a single temperature regulation range and cannot adapt to complex weather changes. And the prepared fabric with the temperature adjusting function has the defect of washing resistance. And the wall material of the phase change capsule is easy to break when being washed, so that the temperature adjusting capability of the phase change capsule is reduced.
Carry out surface treatment to woodwork, metal product, make its surface adhere to and have the looks intelligence microparticle, can exert an influence to ambient temperature, improve the experience sense of people when using.

Detailed Description

In the method for processing an article by using intelligent microparticles according to the embodiment, the processed article is a textile, taking a fabric as an example, and the method specifically includes the following steps: the method comprises the following steps of performing hyperbranched treatment on the surface of the textile, dipping the first intelligent microparticle treatment liquid in the second step, dipping the second intelligent microparticle treatment liquid in the third step, and dipping the second hyperbranched treatment liquid in the fourth step. The hyperbranched treatment is firstly carried out on the surface of the textile, so that the surface of the textile can have polar groups of the hyperbranched polymer. Can improve the bonding fastness with the fiber when the subsequent intelligent corpuscle treatment is carried out.
Carrying out hyperbranched treatment on the surface of the textile: and (3) soaking the textile in the first hyperbranched treatment solution at the temperature of 80-85 ℃ for 5min, and then drying. The textile used is pure cotton fabric.
The hyperbranched treatment liquid comprises 2 mass percent of amino-terminated hyperbranched polymer, 0.5 mass percent of divinyl triamine, 0.5 mass percent of maleic anhydride, 0.1 mass percent of ferric chloride, 0.1 mass percent of copper salt and the balance of deionized water. The copper ions and the iron ions can modify the amino-terminated hyperbranched polymer by the divinyl triamine and the maleic anhydride, so that the amino-terminated hyperbranched polymer can be better combined with fibers with polar groups, and the combination fastness of the amino-terminated hyperbranched polymer and the fibers is improved. The copper salt is one or more of copper sulfate, copper nitrate, copper acetate and copper chloride.
Step two, spraying a first intelligent microparticle treatment liquid: and (3) placing the fabric treated in the last step in an environment of 60-65 ℃, spraying the first intelligent microparticle treatment liquid until the liquid carrying rate is 80%, irradiating for 30-60min by adopting ultraviolet light of A wave band, and drying.
The first intelligent microparticle treatment liquid is formed by uniformly mixing a first oil phase and a first water phase. The first oil phase is formed by uniformly mixing 60-80 parts by mass of a first phase change material, 100 parts by mass of a first wall material, 10-20 parts by mass of an amino-terminated hyperbranched polymer quaternary ammonium salt and 1-2 parts by mass of a photoinitiator at 30-45 ℃; the first aqueous phase comprises 10-20 parts by mass of water-soluble flame retardant, 5-10 parts by mass of glycerin fatty acid ester derivative serving as an emulsifier and 800 parts by mass of deionized water. The photoinitiator used was ferric chloride. The first wall material comprises an acrylate monomer. The wavelength of the ultraviolet light in the A wave band is 315-400nm, and the ultraviolet light in the A wave band can well combine the acrylate monomers with the textile surface which is subjected to hyperbranched treatment. And a water-soluble flame retardant is used, so that the treated fabric has flame retardant property.
Step three, spraying a second intelligent microparticle treatment liquid: and (3) spraying the fabric treated in the last step with a second intelligent particle treatment solution until the liquid carrying rate is 80%, irradiating for 20-40min by adopting ultraviolet light of a B wave band, and drying. The wavelength of the ultraviolet light in the B wave band is 280-315nm.
The second intelligent microparticle treatment liquid is formed by uniformly mixing a second oil phase and a second water phase, wherein the second oil phase comprises 30-50 parts by mass of a second phase change material, 100 parts by mass of a second wall material, 10-20 parts by mass of amino-terminated hyperbranched polymer isocyanate and 1-2 parts by mass of a photoinitiator, and is formed by uniformly mixing at 35-40 ℃. The second water phase comprises 10-20 parts by mass of silver ion antibacterial agent, 5-10 parts by mass of octoxynol serving as an emulsifier and 600 parts by mass of deionized water. The second wall material comprises an unsaturated polyester resin. The ultraviolet light with the wavelength enables unsaturated carbon-carbon double bonds or carbon-carbon triple bonds in the unsaturated polyester resin to be well combined with the hyperbranched polymer on the surface of the textile. The silver ion antibacterial agent is used, so that the fabric has antibacterial capability.
The structure of the intelligent micro-particles attached to the surface of the fiber formed in the two steps is as follows: the first wall material wraps the outer side of the first phase change material, the second phase change material wraps the outer side of the first wall material, and the second wall material wraps the outer side of the second phase change material. And the phase change temperature of the first phase change material is higher than that of the second phase change material, so that the second phase change material is subjected to phase change at low temperature in advance until the temperature is adjusted. After the temperature rises, the second phase-change material can not store energy after completely finishing phase change, namely the temperature can not be regulated, and at the moment, the first phase-change material works to generate phase change and continuously plays a role in regulating the temperature. The arrangement can ensure that the intelligent micro-particles can have good energy storage effect at both lower temperature and higher temperature, and the temperature regulation range of the intelligent micro-particles is expanded.
The first phase change material is polyoxyethylene and modified fatty alcohol-polyoxyethylene ether thereof, and the second phase change material is polyalcohol or polyethylene glycol.
Step four, spraying a second hyperbranched treatment fluid: and (3) spraying a second hyperbranched treatment liquid on the fabric treated in the last step at the temperature of 50-60 ℃, treating for 10-15min under the condition of ultraviolet light of a C wave band, removing the liquid and drying. The second hyperbranched treatment fluid comprises 20-30 parts by mass of hyperbranched star-shaped polymer with end groups containing carbon-carbon double bond groups, 30-50 parts by mass of comb-type amphiphilic polymer SMA-g-MPEG and 200 parts by mass of deionized water.
In the fourth step, the wavelength of the C-band ultraviolet light is 100-280nm. The hyperbranched star polymer with the end group containing carbon-carbon double bond groups in the second hyperbranched treatment liquid can be cured under the action of ultraviolet light, and the comb-type amphiphilic polymer SMA-g-MPEG can reduce the hardness of the cured hyperbranched star polymer and improve the hand feeling of the treated textile. And the hyperbranched star polymer and the SMA-g-MPEG can be well combined with the amino-terminated hyperbranched polymer isocyanate in the second wall material, so that the strength of the wall material of the intelligent microparticle is improved, the wall material cannot be damaged in the washing process, and the loss of the phase change material and the influence on the temperature regulation capacity of the textile are avoided.
And fifthly, three-proofing finishing: spraying the fabric treated in the last step with post-treatment liquid until the liquid carrying rate is 80%, and drying; the post-treatment liquid contains 10 parts by mass of a fluoroacryloyl ester copolymer, 10 parts by mass of a hyperbranched polyamide and 200 parts by mass of deionized water. The hyperbranched polyamide can be well combined with the hyperbranched star polymer and the SMA-g-MPEG, so that the fluoroacryloyl ester copolymer can be well solidified on the surface of the fiber, and the three-proofing effect can be lasting.
For the textile prepared by the embodiment, the weight is increased by 25%, and the latent heat of phase change reaches 56.4J/g. After 5, 10, 20, 50 washes, the rate of weight change and the latent heat of phase change were tested.
