Embodiment 1
[0026] figure 1 Shown: Adjacent sides of arbitrary polymethyl methacrylate plates 1 and 2 are glued together, and the adjacent sides are non-planar matching surfaces that are not perpendicular to the plane of the plexiglass square plate, and the non-planar matching surfaces are 45° inclined plane 3, which is consistent with The plane of the plexiglass square plate is 45°.
[0027] The steps of gluing are:
[0028] (1) Process the side bonding surfaces of two or more polymethyl methacrylate sheets to form mutually matching 45° diagonal bevels or triangular sawtooth surfaces or rectangular sawtooth surfaces;
[0029] (2), the bonding surface of above-mentioned steps processing is carried out processing smooth treatment;
[0030] (3) Carry out preliminary butt jointing of the boards with qualified bonding surface, adjust the boards so that the two boards to be bonded are at the same level, leave a pouring bonding space of 20% of the board thickness between the boards, and follo...

Abstract
The invention relates to a method of adhering and preparing with polymethyl methacrylate, including: processing side adhesive faces of more than two polymethyl methacrylate plates to obtain mutually matched 45-degree diagonal slants, or triangular sawtooth faces, or rectangular sawtooth faces, or arc smooth surfaces; smoothening the processed adhesive faces; preliminarily butting the plates with the adhesive faces processed to qualification, adjusting the plates so that the two plates to be adhered are on a same level, with a pouring adhering space 15-20% of plate thickness reserved between the plates, and adjusting and preliminarily butting the plates to be adhered according to the above steps; molding the pouring adhering spaces between all plates; pre-polymerizing methyl methacrylate and pouring; placing the pour-adhered plates in the environment under a humidity of 50-60% and a temperature of 20-30 DEG C to allow natural polymerization.
Description
technical field [0001] The invention relates to a polymethyl methacrylate adhesive preparation method. Background technique [0002] Polymethyl methacrylate is a thermoplastic material with excellent impact resistance, aging resistance, high light transmittance, etc. It is widely used in advertising signs, craft products, kitchen and bathroom, electronic information, rail transit, aerospace, aquariums, etc. field. With the continuous expansion of its application fields, the market demand for polymethyl methacrylate sheets with super large and thick sizes is strong. At present, due to the limitations of equipment and molds at home and abroad, it is impossible to produce ultra-large and ultra-thick polymethyl methacrylate sheets. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a polyacrylamide with simple production process, low cost, high bonding overall strength, high shear strength, no influence ...
