Abstract
The invention relates to a 109 decoration adhesive. The 109 decoration adhesive is simple in process, long in storage time, is convenient to use, has small pungent odor, has good anti-bacterial performance, and is hard to be soured and to hydrolyze. The 109 decoration adhesive is mainly used for bonding cement mortar and decorative wall cloth materials and the like. The 109 decoration adhesive ischaracterized by being prepared through steps of dissolving polyvinyl alcohol of formulation dosage in water, keeping temperature at 85-88 DEG C, agitating and adding hydrochloric acid and formaldehyde, if sampling viscosity is greater than 100 s, neutralizing with sodium hydroxide till pH is 8.0-8.5, adding OK powder, cooling to 40 DEG C, adding urea till the urea is dissolved completely, then obtaining the 109 decoration adhesive.
Description
technical field [0001] The invention relates to a 109 decorative adhesive and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] 109 Decorative adhesives are rationally prepared from polyvinyl alcohol, OK powder, formaldehyde, sodium hydroxide, urea, hydrochloric acid, water, etc. [0003] 109 Decorative Adhesive is a new product of adhesive. Its main features are: easy to obtain raw materials, simple process, long shelf life, convenient use, small irritating smell, excellent antibacterial property, not easy to rancidity and hydrolysis. It is mainly used for bonding cement mortar and decorative wall covering materials. [0004] 109 Decorative Adhesive has the following characteristics: small irritating odor, excellent antibacterial property, not easy to become rancid and hydrolyzed. [0005] The proportioning ratio of this 109 decorative adhesives has not yet been seen in the reports of scientific and technologic...
