Abstract

the invention provides a photochromic simulation flower, which comprises the following specific components in percentage by weight: 0.5-1 part of phenoxyethanol; 60-90 parts of polyether polyol; 1-3 parts of a chain extender; 2-4 parts of an amine catalyst; 2-4 parts of a foaming agent; 20-40 parts of isocyanate; 1-2 parts of deionized water; 5-10 parts of photochromic MC powder; 3-7 parts of a dispersing agent; 2-5 parts of a water-based light stabilizer. Mixing, placing into a mold, and hot-molding, and optionally adding 3-5 parts of fragrant powder to obtain fragrant photochromic artificial flower. The fragrant photochromic artificial flower obtained by the invention can change color under the sunshine or ultraviolet rays and recover the color under the condition of no sunshine or ultraviolet rays; if a photochromic material that changes color to colorless is used, the opposite effect can be achieved. Realize that colourless change is coloured, coloured change colored effect can release the fragrant smell of corresponding flower simultaneously, and is more lifelike in the sense organ, still has certain ultraviolet ray indicating effect simultaneously, and when outdoor use, the effect is better.

Description

Photochromic simulation flower and preparation method thereof

Technical Field

The invention relates to the technical field of artware, in particular to a photochromic simulation flower.

Background

The simulation flower has larger market demand at present, is widely applied to wedding, opening celebration, restaurant, meeting hall, household and the like, can be very vivid in the prior art, but has much improved space in the aspect of function expansion.

Particularly, most of the simulated flowers on the market at present are common non-discolorable, and few of the simulated flowers are combined in color, shape and aroma.

Disclosure of Invention

The invention aims to provide a photochromic simulation flower and a preparation method thereof.

The technical scheme of the invention is as follows: a photochromic simulation flower is prepared by the following formula:

Firstly, manufacturing petals:

2-4 parts of a foaming agent;

20-40 parts of isocyanate (the mass fraction is 30% -60%);

1-2 parts of deionized water;

5-10 parts of photochromic MC powder;

3-7 parts of a dispersing agent;

2-5 parts of a water-based light stabilizer; photochromic weatherability can be enhanced;

the specific manufacturing method comprises the following steps: 0.5-1 part of phenoxyethanol, 60-90 parts of polyether polyol by weight, 2-4 parts of amine catalyst, 1-3 parts of chain extender,

2-4 parts by weight of foaming agent, 5-10 parts by weight of photochromic MC powder, 3-7 parts by weight of dispersing agent and 2-5 parts by weight of light stabilizer are placed in a stirrer and stirred for 30-40 minutes to be uniformly foamed, the stirring environment temperature is set to be 20-30 ℃, and 1-2 parts by weight of deionized water is added in the stirring process to stir the stirred material into mud.

secondly, preparing a flower stem:

heating polyethylene plastic particles (green or brown) to 120-140 ℃, pouring the heated polyethylene plastic particles into a stem mold for molding, and cooling to obtain the pseudoflower stem.

And (3) preparing a finished product:

And putting the material matrix and the flower stem into various flower type molds for hot-forming to obtain the high-simulation flower.

the invention can also add flavor powder into the formula to prepare the photochromic simulated flower with corresponding fragrance, 3-5 parts of flavor powder is required to be additionally added into the formula, for example, the rose-shaped flavor powder is added, the lily is added with the lily-flavored flavor powder, and the flavor powder has many choices, such as rose flavor, lily flavor, jasmine flavor, tea flower flavor, sweet osmanthus flavor and the like.

The isocyanate mass fraction refers to concentration, the isocyanate is MDI, the functionality is 3, the MDI is diphenylmethane diisocyanate, and the diphenylmethane diisocyanate, the polyether polyol and other auxiliary agents react together to synthesize the polyurethane material.

The light stabilizer is preferably 770, i.e., bis-2, 2,6, 6-tetramethylpiperidinol sebacate.

the dispersing agent is preferably ethoxy modified polytrisiloxane.

the chain extender is a product trade name under the name of BASF: joncry ADR 4400.

The photochromic MC powder, namely the microencapsulated photochromic powder, is a product developed by the applicant, can be obtained by commercial purchase, has multiple selectable colors, and can change color into colorless or colorless into colored.

other ingredients are well known in the art and can be selected by one skilled in the art based on the expertise.

The invention has the advantages and positive effects that: the photochromic simulation flower with the fragrance, which is obtained by the invention, has vivid shape, and simultaneously has corresponding fragrance and is more real. The method is mainly applied to various wedding, opening ceremony, restaurants, meeting halls, households and the like which need simulated flowers, improves the applicability and the interestingness of the method, and has higher additional value. Meanwhile, the artificial flower can change color under the sunshine or ultraviolet rays, can change into various colors such as orange, purple, blue, pink and the like according to the blending of the added photochromic powder compound, and can restore the color under the condition of no sunshine or ultraviolet rays; if a photochromic material that changes color to colorless is used, the opposite effect can be achieved. Realize that colourless change is coloured, coloured change colored effect can release the fragrant smell of corresponding flower simultaneously, and is more lifelike in the sense organ, still has certain ultraviolet ray indicating effect simultaneously, and when outdoor use, the effect is better.
