Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] A method for producing a fast-installed composite roof wall panel, comprising the following steps:

[0016] S1. Selection of raw materials: select melamine, formaldehyde, phenol, kraft paper, sodium hydroxide solution, and glass fiber as raw materials;

[0017] S2. Synthesis of resin: Weigh a certain amount of formaldehyde and phenol, melt the phenol and add it to the mixing tank together with formaldehyde, stir evenly, add a certain amount of sodium hydroxide solution to adjust the pH value to 8.0-9.5, and heat up to At 40-...

Abstract

The invention discloses a production method of a rapid-to-install composite ceiling wall board. The production method includes steps of: S1) raw material selection; S2) resin synthesis; S3) compositewall board preparation; and S4) performance test on the composite wall board and finish product production. Under a weak alkaline condition, melamine, phenol and formaldehyde are subjected to co-condensation to form melamine-phenol-formaldehyde resin, which then serves as a basic resin to prepare a series of laminated boards; by adding glass fibers, the composite ceiling wall board is improved inimpact strength, tensile strength, elasticity modulus and Rockwell hardness; the melamine-phenol-formaldehyde resin has long storage time, and the composite ceiling wall board is improved in formaldehyde release quantity and is enhanced in flame retarding performance.

Description

technical field [0001] The invention belongs to the field of architecture, and in particular relates to a production method of a fast-installed composite roof wall panel. Background technique [0002] High molecular polymer materials are widely used in all aspects of production and life, but at the same time, fires caused by the flammability of high molecular polymer materials have also brought significant casualties and economic losses. Fireproof boards are used for surface decoration. Refractory building materials are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. There are many varieties of fireproof boards, among which phenolic fireproof boards have become one of the varieties that are considered to be satisfactory in performance and competitive in cost, thus having broad application prospects. [0003] However, the flame resistance of the prior art composite roof wallboard is not good enough, so...
