Embodiment 1

[0024] Embodiment 1: see figure 1 , figure 2 and image 3 , a composite material safety toe cap provided in this embodiment, the toe cap is formed by bonding and pressing multiple layers of glass fiber cloth coated with resin paste, the toe cap is hooked by the top surface 1, the side surface 2 and the bottom edge Composed of feet 3, the mass percentages of the resin paste and glass fiber cloth are: 65% to 80% of resin paste, 20% to 35% of glass fiber cloth; wherein the components and mass percentages of the resin paste are as follows: polyester resin 65-80%, initiator 0.2-2%, low-shrinkage additive 10-30%, internal release agent 1-2%, thickener 1-5%, cross-linking agent 1-2%.

[0025] In this embodiment, the polyester resin is preferably vinyl ester resin, the initiator is tert-butyl peroxy-2-ethyl acetate, the low-shrinkage additive is preferably a thermoplastic polymer, and the internal release film The agent is preferably zinc stearate, the thickener is preferably MgO,...

Embodiment 2

[0031] Embodiment 2: The difference between it and Embodiment 1 lies in the components in the composite material safety toe cap and their mass percentages. The components and their mass percentages are as follows: resin paste 65%, glass fiber cloth 35%; wherein the resin paste components and their mass percentages are as follows: polyester resin 75%, initiator 0.2%, low shrinkage Additive 20.3%, internal release agent 1.5%, thickener 1.2%, crosslinking agent 1.8%.

Embodiment 3

[0032] Embodiment 3: The difference between it and Embodiment 1 lies in that the components in the composite material safety toe cap and their mass percentages are different. The components and their mass percentages are as follows: resin paste 80%, glass fiber cloth 20%; wherein the resin paste components and their mass percentages are as follows: polyester resin 65%, initiator 2%, low shrinkage Additive 30%, internal release agent 1%, thickener 1%, crosslinking agent 1%.

Abstract

The invention discloses a composite material safety toe cap which is formed by bonding and pressing multiple layers of glass fiber cloth coated with resin paste, wherein the resin paste comprises polyester resin, an initiator, a low-shrink additive, an inner release agent, a thickener and a crosslinking agent; and the invention also discloses a method for manufacturing the composite material safety toe cap. The formula of the composite material safety toe cap provided by the invention is scientific and reasonable in design, has good mechanical performance and high strength, greatly enhances the impact resistance, effectively avoids the phenomena that the foot of a user kicks a foreign object or is bruised by the falling foreign object and the toes are injured, and realizes high safety; the composite material safety toe cap has the advantages of corrosion resistance, high temperature resistance, cold resistance, acid resistance and the like, and the service life is greatly prolonged; and the composite material safety toe cap can pass the International test standards such as European Union EN12568-S, Canada CSA-Z195 and the United States ASTM-F2413 and the like. The method provided by the invention has a simple manufacturing technology, is easy to realize and can quickly produce a composite material safety toe cap.

Description

technical field [0001] The invention belongs to the technical field of toe caps, in particular to a composite material safety toe cap and a manufacturing method thereof. Background technique [0002] Labor insurance in today's society has become a problem that every laborer is concerned about. Therefore, there are many labor insurance facilities in various aspects. A safety toe cap for protecting the personal safety of laborers is one of them. It is to have a safety toe cap with a certain mechanical strength on the head of the shoes to prevent kicking foreign objects or being crushed by falling foreign objects and injuring toes during walking or working. [0003] Safety toe caps made of metal are very safe and have been used for many years, but they are heavy and make it difficult for the wearer to move; they are also easily corroded by moisture or chemicals, which poses a safety hazard. Coupled with the prevalence of terrorism in recent years, airports, ports, and various ...
