Problems solved by technology
[0005] The purpose of the present invention is to provide a formaldehyde-free flame-retardant waterproof glue and its preparation method to solve the problems in the prior art that the urea-formaldehyde glue, melamine-modified urea-formaldehyde glue, and MDI glue used in various boards have poor waterproof performance and will deform when exposed to moisture. , will disperse and pulverize when it meets water, and more importantly, these products are not flame retardant. The flammability and flammability of the products have not changed, but because the glue is flammable, it will burn more serious problems.

Abstract
The invention is applicable to the technical field of waterproof glue, and provides formaldehyde-free flame-retardant waterproof glue and a preparation method thereof.The formaldehyde-free flame-retardant waterproof glue is prepared from, by mass, 20-25 parts of biomassprotein, 5-12 parts of waterborne high-molecular isocyanate, 3-8 parts of water glass, 1-3 parts of borax, 3-5 parts of polysilazane, 1-3 parts of flame-retardant powder, 0.2-0.4 part of preservative and 0.1-0.5 part of thickener; according to the formaldehyde-free flame-retardant waterproof glue and the preparation method thereof, the formaldehyde-free flame-retardant waterproof glue can be applied to gluing of various artificial boards, zero formaldehyde is achieved, the formaldehyde-free flame-retardant waterproof glue has the comprehensive effects of flame retardance, water resistance, corrosion resistance, mildew resistance and the like, the cost is low, the cost is 2 / 3 lower than that of common formaldehyde-free glue (not flame-retardant and not waterproof) such as MDI, and the formaldehyde-free flame-retardant waterproof glue is prepared by adding the polysilazane and utilizing the unique Si-NH-Si bond of the polysilazane. The adhesive has good binding force and good mechanical properties, is high in hardness after being cured, and has the function of resisting alcohols, ketones and other organic solvents.
Description
Technical field [0001] The invention involves the field of waterproofing technology, which is specifically for a kind of flame -free waterproof waterproofing and preparation methods. Background technique [0002] In recent years, the harm of formaldehyde has been more and more valued. Formaldehyde is a colorless and soluble irritating gas, which has great harm to the human body. Wood products made of formaldehyde adhesives are used indoors. The formaldehyde release period can be longer. For 15 years, the effects of formaldehyde on human health are mainly manifested in the aspects of smell, stimulation, allergies, abnormal lung function, abnormal liver function, and abnormal immune function. Long -term contact with low -dose formaldehyde can cause chronic respiratory diseases, causing nasopharyngeal cancer, and nasopharyngeal cancer. Estalidal cancer, brain tumor, menstrual disorders, gene mutations, nucleusnucleus, DNA single -chain internal intercourse and DNA and protein inter...
