Problems solved by technology

[0004] Patent application CN201110289701.8 discloses a flame-retardant backsheet for solar cell modules, the flame-retardant flexible backsheet is a flame-retardant layer formed of non-metallic inorganic fiber fabric and bonded to the first side of the flame-retardant layer The first polymer layer on the top, in this invention, an inorganic fiber fabric with a large surface area per unit mass is used, which has poor temperature resistance, and the problem of high temperature conduction still exists, which is likely to cause problems such as thermal melting and cracking of the backplane plastic material
And the poor thermal barrier will also affect the phenomenon that the material behind the backplane has been peeled off.

Embodiment 1

[0066] This embodiment provides a high-barrier flame-retardant backplane, the structure of which includes: a structural layer and an adhesive layer, the adhesive layer is located at the bottom of the backplane; the structural layer is located at the top of the backplane;

[0067] The thickness of the adhesive layer is 100 μm;

[0068] The thickness of the structural layer is 300 μm.

[0069] The raw materials of the adhesive layer, in parts by weight, include the following components: 12 parts of polyethylene wax, 2 parts of antioxidants, 2 parts of light stabilizers, 15 parts of auxiliary agents, and 110 parts of polyethylene.

[0070] The polyethylene wax had a weight-average molecular weight of 3000, a viscosity of 550 mPa·s, 220° C., and was purchased from Ningbo Weiye Plastic & Chemical Co., Ltd.

[0071] The antioxidant is a mixture of antioxidant 1010 and antioxidant 168. The weight ratio of the antioxidant 1010 to the antioxidant 168 is 1:1.

[0072] The light stabi...

Embodiment 2

[0098] The specific implementation of Example 2 is the same as that of Example 1; the difference is that the raw materials of the structural layer described in Example 2, in parts by weight, include the following components: 100 parts of polyolefin, 5 parts of flame retardant, and 20 parts of solid filler parts, 2 parts of curing agent, 15 parts of auxiliary agent. The flame retardant is a modified phosphorus-nitrogen composite material.

Embodiment 3

[0100] The specific implementation of Example 3 is the same as that of Example 1; the difference is that the raw materials of the adhesive layer described in Example 3, in parts by weight, include the following components: 15 parts of polyethylene wax, 3 parts of antioxidant, 3 parts of stabilizer, 20 parts of auxiliary, and 120 parts of polyethylene.

Abstract

The invention relates to a flame-retardant backboard (IPC classification number: H01 / L31049), in particular to a high-barrier-property flame-retardant backboard and a preparation method thereof. The invention provides a high-barrier-property flame-retardant backboard which structurally and mainly comprises a structural layer and a bonding layer, and the bonding layer is located at the bottom of the backboard. The structural layer is located at the top of the back plate; and the structural layer and the bonding layer are fixedly connected through co-extrusion. The bonding layer is prepared from the following raw materials in parts by weight: 10 to 15 parts of polyethylene wax, 0.1 to 3 parts of antioxidant, 0.1 to 3 parts of light stabilizer, 10 to 20 parts of additive and 100 to 120 parts of polyethylene. The structural layer at least comprises the following raw materials in parts by weight: 80-100 parts of polyolefin, 5-20 parts of solid filler, 1-5 parts of a curing agent and 5-15 parts of an auxiliary agent. The backboard prepared by the invention has high barrier and flame retardant properties.

Description

technical field [0001] The invention relates to a flame-retardant backboard (IPC classification number: H01 / L31049), in particular to a high-barrier flame-retardant backboard and a preparation method thereof. Background technique [0002] With the progress of society and economic development, people have higher and higher requirements for the energy industry and environmental protection. Therefore, environmentally friendly new energy industries such as solar energy, wind energy, and tidal energy have received extensive and strong support from governments around the world. has developed rapidly. Among them, the solar photovoltaic power generation industry is the most widely developed. Thousands of photovoltaic cells are quietly built on the roof, but the construction of large-scale photovoltaic cell modules also brings safety hazards, among which the fire hazards are among them. The biggest hidden problem. [0003] With the continuous development of photovoltaic modules in ...
