Embodiment 1

[0026] Using starch as a matrix and untreated aloe bark powder as a filler, a degradable buffer foaming material was prepared. The method was as follows: starch (100 parts) was mixed with an appropriate amount of distilled water (100 parts), and glycerin (7 parts) was added in turn. , ethylene glycol (14 parts), untreated aloe bark powder (20 parts), the mixture is placed in a constant temperature oil bath and stirred at a constant speed, and then molded, and its specific preparation process is as follows:

[0027] The first step: dry the aloe bark powder;

[0028] Step 2: Mix the starch with an appropriate amount of distilled water, and add plasticizer and untreated aloe bark powder in sequence, and place the mixture in a constant temperature oil bath at 65°C and stir for 30 minutes at a constant speed;

[0029] Step 3: Put the prepared mixture into a mold with a fixed shape, and use a flat vulcanizer to foam. The processing temperature of the flat vulcanizer is 150°C, the pr...

Embodiment 2

[0033] With starch as the matrix, aloe bark powder treated with blanching and coupling agent is used as filler to prepare a degradable buffer foaming material. The method is as follows: mix starch (100 parts) with appropriate amount of distilled water (100 parts), and successively Add glycerin (7 parts), ethylene glycol (14 parts), untreated aloe bark powder (20 parts), place the mixture in a constant temperature oil bath and stir at a constant speed, and then carry out compression molding. The specific preparation process is as follows:

[0034] The first step: carry out broom treatment to aloe bark powder, in lye, the lye used is the mass fraction of 12% NaOH solution, soak in 1h, wash to neutrality and then dry, add in dried aloe bark powder Silane coupling agent KH550 (0.2 parts) is evenly dispersed and then dried again;

[0035] The second step: mix the starch with an appropriate amount of distilled water, and add the plasticizer and the treated aloe skin powder in turn, ...

Abstract

The invention relates to a method for preparing degradable cushioning materials, and belongs to the field of aloe vera husk powder treatment and application. The method for preparing the degradable cushioning materials includes mixing starch and distilled water with each other to prepare starch adhesive with the starch mass concentration of 50%, sequentially adding plasticizers and aloe vera huskpowder into the starch adhesive and stirring the plasticizers, the aloe vera husk powder and the starch adhesive at the constant temperature of 60-70 DEG C for 30 min to obtain mixtures; placing the mixtures in molds, carrying out foaming by plate vulcanizing machines at the processing temperatures of 150 DEG C under the pressures of 5 MPa for the foaming time of 1 min and carrying out cooling until the temperature reach the room temperature to obtain the degradable cushioning materials. The method has the advantages that the environmental problems and resource waste due to inappropriate treatment on the aloe vera husk powder can be effectively solved by the aid of the method, and research bases and practical guidance significance can be provided to applying the aloe vera husk powder to the field of biomass materials.

Description

technical field [0001] The invention relates to a preparation method of a degradable buffer material, which belongs to the field of processing and application of aloe skin powder. Background technique [0002] The aloe epidermis mainly includes active substances such as aloin and aloin, which have bactericidal, anti-inflammatory and anti-ultraviolet effects. Aloe bark is usually used as a by-product of the aloe processing industry. In recent years, it is mainly used in the feed processing industry, and its true value has not been fully utilized. A large amount of aloe bark is burned and discarded, causing a great burden on the environment. Aloe skin powder contains a large number of hydroxyl groups, so it has high polarity, and there are hydrogen bonds between molecules and molecules. Aloe skin powder contains a large amount of antibacterial ingredients, and as a natural polymer material, it can be degraded without pollution and is environmentally friendly. The preparatio...
