Problems solved by technology

[0004] However, due to the addition of inorganic materials, the existing hand-made model materials have slow curing speed and poor durability; at the same time, they are prone to yellowing under ultraviolet irradiation conditions, which damages the appearance of the product

preparation example 1

[0081] Take 20g of paraffin and heat it to above 60°C, liquefy the paraffin, put it into 50mL of 20wt% hydrogen peroxide, stir and react at 40°C for 15min, quickly transfer it to an ice-water bath and cool it to room temperature, the paraffin is condensed into particles, filtered, washed with water until neutral, and then The modified paraffin wax 1 was obtained by placing the paraffin wax modified by the surface hydroxyl group in a vacuum drying oven at 25-30° C. and drying. After testing, the number of hydroxyl groups on the surface of the modified paraffin wax obtained was 0.132 mmol / g.

preparation example 2

[0083] The operation of this example is similar to that of Example 1, except that the concentration of hydrogen peroxide is 15%wt, the reaction temperature is 60°C, and the reaction time is 5min to obtain modified paraffin 2, and the number of surface hydroxyl groups of the obtained modified paraffin 2 is 0.164 mmol / g.

preparation example 3

[0085]The operation of this example is similar to that of Example 1, except that the concentration of hydrogen peroxide is 5% wt, the reaction temperature is 60° C., and the reaction time is 30 min to obtain modified paraffin 3, and the number of surface hydroxyl groups of the obtained modified paraffin 3 is 0.253 mmol / g.

Abstract

The invention provides a hand-made model material and a preparation method thereof. The material is composed of A component and B component, A component includes: first polyether polyol, isocyanate, glycerin, solid filler; B component includes: second polyether polyol, surface hydroxyl modified paraffin, catalyst , curing agent, hindered phenolic antioxidant, hindered amine light stabilizer, solid filler. The figure material of the present invention is a material with a clay structure, and based on the material of the clay structure, under the condition of no mold, the preparation of the initial model of the figure can be realized directly by kneading; High compressive strength and plasticity, so the initial model can be sculpted directly and shaped directly after sculpting without additional processing. Therefore, the figure material of the present invention has broad application prospects because it can be directly kneaded and sculpted without a figure mold.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a hand-made model material and a preparation method thereof. Background technique [0002] Figures refer to modern collectible models, such as models of people, cars, buildings, videos, plants, insects, ancient creatures, or fantasy things. In addition, the figure is a resin model (ie, GARAGE KIT, GK for short) that expresses the personality of the prototyper, and refers to a model kit that is not mass-produced. Because of the small production and the high difficulty in the complexity of the mold, the price of the figure is generally very expensive. [0003] When making a figure model, because it needs to express very detailed details and characters, there are more requirements for the figure model material. Existing hand-made model materials usually use polymer resin as the basic material, and inorganic materials such as clay can also be used. In addition, for the existing ...
