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 protective material for discrete resin bonding molding and a preparation method thereof. The preparation method comprises the following steps: S1: uniformly distributing resin particles on a molding mold in a flat plate shape; S2: placing the resin particles on the molding mold in S1 The metal frame with the bottom surface of the metal mesh is turned over by an overturning device, so that the distributed resin particles are transferred into the metal frame; S3: the resin particles in the metal frame in S2 are evenly sprayed with an adhesive, and pre-cured by heating; S4: Lay the base fabric on the surface of the metal frame in S3, heat and cure, take out the base fabric from the metal frame, and obtain the protective material bonded and molded by discrete resin. The preparation method of the present invention adopts a discrete resin bonding molding process to ensure clear gaps between resin particles and excellent soft and air-permeable performance; the flat-plate molding mold can be used for customized production according to customer needs, reducing the cutting and cutting process of protective materials and improving the production efficiency. Production efficiency of end-wear protection products.

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...
