Embodiment 1

[0019] Such as Figure 1~2 As shown, in the embodiment of the present invention, a composite glass fiber cloth with good flame retardancy includes a main body 4, a buffer layer 2 for protecting the main body 4 is provided in the middle of the main body 4, and the two sides of the buffer layer 2 are symmetrical A fireproof layer 1 is provided for fireproofing, the fireproof layer 1 and the buffer layer 2 are connected by an adhesive layer 3, and the side of the fireproof layer 1 away from the buffer layer 2 is provided with a coating layer;

[0020] The fire-proof layer 1 is made of fiberglass cloth, and the setting of the fire-proof layer 1 can play the role of fire prevention and flame retardancy;

[0021] The coating layer is made of PU polyurethane material;

[0022] The material of the buffer layer 2 is made of PU foam material, and the PU polyurethane buffer foam can well perform buffering and shock absorption functions, and at the same time, the buffer layer 2 and the f...

Embodiment 2

[0025] A kind of preparation method based on the good composite glass fiber cloth of flame retardancy described in embodiment 1, the steps are as follows:

[0026] S1. Put the fireproof layer 1 on the polyurethane coating equipment, then turn on the polyurethane coating equipment, coat the polyurethane on the outer surface of the fireproof layer 1, and use a scraper to clean the outer surface of the fireproof layer 1 after coating;

[0027] S2. Coating the adhesive layer 3 on the upper surface of the buffer layer 2, then placing the adhesive layer 3 on the calender, placing a layer of fireproof layer 1 on the upper and lower substrate frames of the calender, and mixing the evenly stirred adhesive layer 3 Coating on the buffer layer 2, and then pressing the fireproof layer 1 and the buffer layer 2 together;

[0028] S3. After the pressing is completed, put the finished product into an oven for baking and curing. The oven baking time is five minutes, and the baking temperature i...

Abstract

The invention discloses composite glass fiber cloth with good flame retardance, belongs to the technical field of glass fiber cloth, and solves the problem that existing composite glass fiber cloth ispoor in fire resistance and flame retardance. The composite glass fiber cloth is technically characterized by comprising a main body, wherein a buffer layer used for protecting the main body is arranged in the middle of the main body, fireproof layers used for fire prevention are symmetrically arranged on the two sides of the buffer layer, the fireproof layers are connected with the buffer layerthrough bonding layers, and coating layers are arranged on the sides, which are away from the buffer layer, of the fireproof layers; and the composite glass fiber cloth prepared after the fireproof layers and the buffer layer are compounded can achieve fireproof, heat-insulating and insulating properties while meeting the buffer requirement of the battery cell, the escape time can be prolonged, and the life safety of a user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass fiber cloth, in particular to a composite glass fiber cloth with good flame retardancy and a preparation method thereof. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. Its components are silica, alumina, calcium oxide, boron oxide, magnesium oxide and sodium oxide, etc. It is made of glass balls or waste glass through high-temperature melting , wire drawing, winding, weaving and other processes, and finally form various products. The diameter of glass fiber monofilament ranges from a few microns to more than 20 microns; glass fiber products are brittle and easy to break just like glass; moreover, they have poor wear resistance and are easily damaged after long-term use. Scratches on the surface can cause irreparable wear. [0003] Chinese patent CN208841968U discloses a high-permeability composite glass fiber cloth, which includes at lea...
