Embodiment 1

[0018] Embodiment 1 (compared with the raw material of Table 1 Embodiment 1 and the proportioning value by weight): 5 parts of nanocellulose, 1 part of nano-SiO 2 , 0.8 parts of KH550 type γ-aminopropyltriethoxysilane (referred to as KH550 coupling agent) is added to 69 parts of polyvinyl butyral (PVB), fully stirred in the cone mixer, and sent through the feeder Put it into a twin-screw extruder, heat it to 145°C for mixing and extrusion, and extrude and cast it through a die to make a multi-component PVB diaphragm with a thickness of 0.39mm (abbreviated as this diaphragm) ).

[0019] All the other embodiments 2-8 are compared with the raw materials and weight ratios of the corresponding examples in Table 1, and the diaphragm is made in the same way as in Example 1. Considering the comprehensive performance of the diaphragm, examples 6 and 7 are used. preferred.

[0020] Now this diaphragm test performance that is made by embodiment 1-8 is introduced in table 2:

Abstract

The invention relates to a high tensile strength multicomponent mixed inclusion PVB diaphragm. The diaphragm comprises the following raw materials, by weight, 69-93 parts of the PVB, 1-10 parts of an ultraviolet light absorbent, 5-20 parts of nanometer cellulose, and 0.8-1.2 parts of a silane coupling agent. A production diaphragm of the diaphragm is characterized in that: the nanometer cellulose, the ultraviolet light absorbent and the silane coupling agent are added to the PVB according to above proportions, the raw materials are fully stirred in a tapered mixer, sent to a double screw extruder by a feeder, heated to 140-150DEG C, mixed, extruded, and subjected to extrusion tape casting by a die head to prepare the PVB diaphragm with the thickness of 0.38-0.76mm. The molecular level nanometer cellulose for the production of the diaphragm contains abundant hydroxyl groups which are reacted with nanometer TiO2 to generate titanium-based alcohol, and the titanium-based alcohol is reacted with Si-OH on the glass surface to generate firmly combined Ti-O-Si bonds, so a netted structure is finally formed, thereby the tensile strength, the plasticity and the bonding intensity with glass of the diaphragm are substantially improved.

Description

technical field [0001] The invention relates to the technical field of polymer material modification, in particular to a high-tensile-strength multi-component mixed-inclusion PVB diaphragm and a production method thereof. Background technique [0002] With the improvement of people's living standards, the design of residential and commercial facilities mainly considers the function, aesthetics, environmental protection and buildability of the building, but the glass material used in large quantities in the building is a weak link in the building structure and must be The low probability of natural disasters and malicious attacks should be considered. Therefore, as an important form of safety glass, laminated glass with PVB film in the middle is widely used because of its good impact resistance and penetration resistance, no fragments splash after breaking, and at the same time reduce noise pollution and light pollution to a certain extent. Automotive, construction, security...
