Embodiment 1

[0041] An adhesive for helmet prepregs, comprising in parts by weight:

[0042] Epoxy resin, 200 parts;

[0043] Biological protein solution, 15 parts;

[0044] Cyclohexanone peroxide, 10 parts;

[0045] p-Benzoquinone, 5 parts;

[0046] Acrylic acid, 5 parts;

[0047] Magnesium oxide, 10 parts;

[0048] calcium carbonate, 10 parts

[0049] Calcium stearate, 6 servings.

[0050] Wherein, the epoxy resin is composed of E-44 epoxy resin and W-95 epoxy resin, and the mass ratio of E-44 epoxy resin and W-95 epoxy resin is 4:1.

[0051] After testing, the adhesive in Example 1 has a viscosity of 1250 cps at a temperature of 25°C.

[0052] A certain amount of biological protein is added to the raw material of the adhesive in this embodiment, so that the adhesive can maintain a high viscosity at room temperature. In addition, calcium chloride, magnesium chloride, and calcium stearate are added to facilitate the high-temperature stamping and forming process of the helmet. Afte...

Embodiment 2

[0067]This embodiment is basically the same as Embodiment 1, the difference is:

[0068] 12 parts of biological protein solution.

[0069] After testing, the adhesive in Example 2 has a viscosity of 1020 cps at a temperature of 25°C.

Embodiment 3

[0071] This embodiment is basically the same as Embodiment 1, the difference is:

[0072] Epoxy resin, 180 parts.

[0073] After testing, the adhesive in Example 3 has a viscosity of 975 cps at a temperature of 25°C.

Abstract

The invention discloses an adhesive and a preparation method thereof and a helmet, wherein the adhesive comprises the following components: epoxy resin, cyclohexanone peroxide, p-benzoquinone, magnesium oxide, acrylic acid, calcium carbonate, calcium stearate and bioprotein. The adhesive disclosed by the invention can keep relatively high viscosity at normal temperature. When the adhesive is used for preparing the helmet, energy-consumption-free production is realized, the production efficiency is greatly improved, the production cost is reduced, and meanwhile, personnel safety accidents caused by high-temperature airflow are avoided. In addition, the helmet prepared from the adhesive is better in bulletproof performance.

Description

technical field [0001] The invention relates to the technical field of helmets, in particular to an adhesive, a preparation method thereof and a helmet. Background technique [0002] At present, in the domestic bulletproof helmet industry, the process of processing the helmet body is to apply the non-adhesive phenolic resin material at room temperature to fiber material fabrics such as ultra-high molecular weight polyethylene fibers, aromatic polyamide fibers, and polystyrene heterocyclic fibers. to form a prepreg for the helmet. [0003] During specific processing, after the prepreg is cut into a certain shape, the cut piece is placed on the mold according to the predetermined position. At the same time, the personnel hold the cut piece in one hand and a heat gun in the other hand, and continuously heat the prepreg cut pieces with high-temperature airflow. At each position, the phenolic resin is heated to produce stickiness, pasted on the mold, and the cut piece is flatten...
