preparation example Construction

[0030] The present invention provides a method for preparing a discrete resin-bonded protective material, comprising the following steps:

[0031] S1: Prepare a flat plate forming mold with a thickness of 3-100mm, a length of 100-2000mm, and a width of 100-2000mm. Many small holes are evenly distributed on the flat mold. The small holes can be arranged to form various patterns. The gap between the small holes The size of the hole is between 0.1-5mm, the hole depth is 0.6-5mm, the size of the hole is the size of the horizontal plane, and the distance between any two points is 1-20mm. The resin particles are evenly distributed in the small holes of the flat mold, so that each small hole is filled. filled with resin particles;

[0032] The patterns formed by the small holes are triangles, quadrilaterals, pentagons, polygons, irregular patterns or the shape of the sleeves of clothes, the shape of the front piece, the shape of the back piece or the shape of the palm of the glove; i...

Embodiment 1

[0043] Preparation of a discrete resin-bonded protective material:

[0044] The die hole on the flat plate forming mold is designed to be the shape of the front piece of clothes. The thickness of the flat die is 10mm, the length and width are 70cm×60cm, the die hole size on the die is 15mm, the hole depth is 2mm, and the gap between the die holes is 0.5 mm.

[0045] First, evenly distribute circular nylon glass fiber particles with a diameter of 14.5mm in the die holes of the flat mold, so that each hole is filled with particles. Secondly, put the flat mold filled with nylon glass fiber particles on the flipping device, and then place a metal frame of 80cm×70cm on the mold, and transfer the resin particles on the mold to the metal mesh of the metal frame by controlling the flipping device bottom surface. Again, spray polyurethane liquid adhesive evenly on the resin particles in the metal frame, the excess adhesive flows down from the mesh holes of the metal mesh on the botto...

[0048] Preparation of a discrete resin-bonded protective material:

[0049] The die hole on the flat plate forming mold is designed to be the shape of the palm surface and the palm back of the glove. The thickness of the flat die is 10mm, and the length and width are 50cm×40cm. The die hole size on the mold is 4mm, and the hole depth is 0.8mm. The gap is 0.2mm.

[0050] First, evenly distribute circular polycarbonate particles with a diameter of 3 mm in the die holes of the flat mold, so that each hole is filled with polycarbonate particles. Secondly, place the flat mold filled with particles on the turning device, and then place a 60cm×50cm metal frame on the mold, and transfer the resin particles on the mold to the metal mesh bottom surface of the metal frame by controlling the turning device. Again, spray polyester-type hot melt adhesive powder evenly on the resin particles above the metal frame, and the excess hot melt adhesive powder flows down from the mesh holes of the...

Abstract

The invention relates to a discrete resin bonding and forming protective material and a preparation method thereof. The preparation method comprises the following steps that S1, resin particles are uniformly distributed in a forming mold of a flat plate shape; S2, a metal frame with a metal mesh bottom surface is placed on the forming mold in the S1, the metal frame is turned over by using a turnover device, and the resin particles which are distributed are moved into the metal frame; S3, a binder is uniformly sprayed on the resin particles in the metal frame in the S2, and heating and pre-curing are conducted; and S4, base cloth fabric is laid on the surface of the metal frame in the S3, heating and curing are conducted, the base cloth fabric is taken out from the metal frame, and the discrete resin bonding and forming protective material is obtained. According to the discrete resin bonding and forming protective material and the preparation method thereof, a discrete resin bonding and forming process is adopted, it is guaranteed that gaps among the resin particles are clear, and the soft and breathable performance is excellent; and the flat plate forming mold can be customized for production according to customer requirements, a clipping and cutting procedure of the protective material are reduced, and the production efficiency of a terminal wearing protective product is improved.

Description

technical field [0001] The invention relates to the field of functional protective materials and manufacturing techniques thereof, in particular to a protective material bonded and molded by discrete resins and a preparation method thereof. Background technique [0002] In recent years, people have become more and more aware of the importance of their own safety protection. Whether it is in the daily life of individuals, or in industrial fields such as mechanical processing, slaughtering, and construction, the awareness of protection is increasing day by day. Especially in some heavy industry fields, practitioners are in frequent contact with hard materials such as steel, glass, and plates, and are vulnerable to injury. It is necessary to wear corresponding personal protective equipment for special work, and more and more enterprises and individuals are gradually strengthening self-defense. In addition, public security, auxiliary police, and police officers, including ordin...
