Abstract
The invention discloses a slow-resilience polyurethane foaming pillow containing plant flower and grass powder and a preparation method thereof, and the preparation method is characterized in that the process of the traditional slow-resilience polyurethane foaming pillow is improved, natural plant flower and grass powder is used as a filler to replace the traditional mineral filler, and the odor of natural plant pigment and flower and grass powder is used for coloring and perfuming the foam body, so that various problems caused by the traditional filler, color paste and essence are solved, a certain nursing and health-care effect is provided for the foam body, the density of the traditional slow-resilience polyurethane foaming pillow is reduced, the possibility of pollution to a water body caused by the traditional color paste is avoided, the fragrance retaining time of the foam body is prolonged, and the possibility of stimulation to the skin caused by color paste and essence is avoided.
Description
Technical Field
The invention relates to the technical field of slow-rebound polyurethane foaming, in particular to a slow-rebound polyurethane foaming pillow containing plant flower and plant powder and a preparation method thereof.
Background
At present, light calcium carbonate is usually used as a main filler or no filler in the traditional polyurethane slow rebound pillow foaming, a mineral type color paste or a resin type color paste is used for coloring a foam body, and essence is used for perfuming the foam body. This has the following problems: fillers such as light calcium carbonate and kaolin can increase the foam quality; color pastes are easy to decolorize and contain heavy metal elements such as lead compounds and the like; the essences are volatile, cannot keep fragrance for a long time, and are easy to cause skin allergy.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a slow rebound polyurethane foam pillow containing plant flower powder and a preparation method thereof by improving the process of the traditional slow rebound polyurethane foam pillow. According to the invention, natural plant flower and grass powder (lotus leaf powder, rose pollen, lavender powder, citronella grass powder, jasmine pollen, green tea powder, mulberry leaf powder, chrysanthemum powder, plum blossom powder, osmanthus flower powder and the like) is adopted as a filler to replace the traditional mineral filler, and meanwhile, the natural plant pigment and the smell of the flower and grass powder are used for coloring and perfuming the foam body, so that various problems caused by the traditional filler, color paste and essence are solved, meanwhile, a certain nursing and health care effect is given to the foam body (such as volatile oily substances contained in jasmine, the effects of promoting qi circulation, relieving pain, relieving depression and dispersing stagnation, lavender essential oil is helpful for sleeping and the like), the density of the traditional slow rebound polyurethane foam pillow is reduced, the possibility of pollution to water bodies caused by using the traditional color paste is avoided, the fragrance retaining time of the foam body is prolonged, and the possibility of skin irritation caused by color paste and essence is avoided.
In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the invention provides a slow-rebound polyurethane foam pillow containing plant flower and grass powder, which is prepared from a component A and a component B in a mass ratio of A: b is 100: 42-48, wherein the component B is MDI prepolymer; the component A is prepared from the following raw materials in percentage by weight:
as a preferred embodiment, the mass ratio of the a component to the B component a: b is 100: 42.
in a preferred embodiment, the floral powder is selected from any one of lotus leaf powder, rose powder, lavender powder, citronella powder, jasmine powder, green tea powder, mulberry leaf powder, chrysanthemum powder, plum flower powder and osmanthus flower powder.
As a specific embodiment, the preparation method of the flower and grass powder comprises the following steps: drying the flowers and plants at 55 ℃ in an air-isolated mode, and crushing the dried flowers and plants into powder with the particle size of 400 meshes to obtain the flower and plant powder.
As a preferred embodiment, the B component is selected from the group consisting of New Youda materials, Inc. of Dongguan
MDI isocyanate.
The component B comprises the following raw materials in parts by weight:
as a specific embodiment, the component B consists of the following raw materials in parts by weight:
as a more specific preferred embodiment, the preparation method of the component B comprises the following steps: mixing B1, B2, B3, B4, B5 and B6 in the component B according to a proportion, and completely dispersing at the speed of 360 revolutions per minute by using a homogenizing stirring cylinder at the temperature of 30 ℃ under the normal pressure to obtain the component B.
