preparation example Construction

[0035] see figure 1 , the preparation method of above-mentioned deformation material, comprises the following steps:

[0036] S110. Stir 20-40 parts of SEEPS and 10-25 parts of white oil until the SEEPS completely absorbs the white oil.

[0037] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring speed of the high-speed mixer is 250r / min-400r / min, and the stirring time is 10min-15min.

[0038] S120. Add 15-35 parts of petroleum resin and 0.2-0.3 parts of antioxidant to the SEEPS that has completely absorbed the white oil and continue stirring.

[0039] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring rate of the high-speed mixer is 250r / min-400r / min, and the stirring time is 3min-5min.

[0040] S130, adding 10-30 parts of plasticizer and continuing to stir to obtain a premix.

[0041] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring rate of the high-speed mixer is 250r / min-400...

Embodiment 1

[0047] Stir 20 parts of SEEPS and 10 parts of paraffin oil in a high-speed mixer for 10 minutes until SEEPS completely absorbs the paraffin oil. The rotational speed of the mixer is 400r / min. Add 35 parts of carbon-5 hydrogenated petroleum resin and 0.2 part of (3,5-di-tert-butyl-4-hydroxyphenyl) propionate octadecanoate to the SEEPS that has completely absorbed paraffin oil and continue stirring for 3 minutes . Add 10 parts of diisononyl cyclohexane 1,2-dicarboxylate and continue to stir to obtain a premixture, and the stirring time is 3 minutes. The premix is ​​plasticized, extruded and granulated in a twin-screw extruder to obtain a deformed material. The temperature of the twin-screw extruder is 60° C., and the rotation speed is 700 r / min.

Embodiment 2

[0049]Stir 20 parts of SEEPS and 25 parts of paraffin oil in a high-speed mixer for 12 minutes until SEEPS completely absorbs the paraffin oil. The rotational speed of the mixer is 250r / min. Add 15 parts of carbon-9 hydrogenated petroleum resin, 5 parts of PE wax and 0.3 part of tris(2,4-di-tert-butylphenyl)phosphite to the SEEPS that has completely absorbed paraffin oil and continue stirring for 5 minutes. Then add 20 parts of diisononyl phthalate and continue to stir to obtain a premix, and the stirring time is 5 minutes. The premix is ​​plasticized, extruded and granulated in a twin-screw extruder to obtain a deformed material. The temperature of the twin-screw extruder is 80° C., and the rotation speed is 500 r / min.

Abstract

The invention relates to a deformation material, prepared from the following components in parts by mass: 20-40 parts of SEEPS, 10-25 parts of white oil, 10-30 parts of a plasticizer, 15-35 parts of petroleum resin and 0.2-0.3 part of an antioxidant. According to the deformation material, the SEEPS is used as a base material, the white oil, plasticizer, petroleum resin and antioxidant are used as auxiliary materials, and through reasonable proportioning, the binding property of the deformation material can be increased, and the elasticity and intensity of the material are reduced, thereby obtaining the deformation material with a lower deformation temperature. As shown by test data, the deformation temperature of the deformation material is 70-90 DEG C, the deformation temperature is lower, so the deformation material is safer in the use process for children.

Description

technical field [0001] The invention relates to the technical field of toy materials, in particular to deformation materials and a preparation method thereof. Background technique [0002] With the continuous expansion of the children's toy market, the demand for materials for preparing toys is increasing, and the safety requirements and innovation of materials are also gradually expanding. Toys made of deformable materials are generally suitable for children aged 6 or above. The deformable materials can be deformed arbitrarily after heat treatment, and show a certain degree of elasticity after cooling to room temperature, and cannot be deformed. Toys made of deformable materials can be reused and have certain educational properties. [0003] However, the currently commonly used deformation materials generally have a high deformation temperature, which poses a certain safety risk to children. Contents of the invention [0004] Based on this, it is necessary to provide a ...
