Methods for preparing stable urea formaldehyde polyvinyl alcohol colloids
The mechanical properties of urea formaldehyde resins may be improved by incorporating therein polyvinyl alcohol. The polyvinyl alcohol may be incorporated during pre-mixing, mid mixing, and/or post mixing of the resin components. Resins prepared using polyvinyl alcohol are particularly desirable in...

| description | The mechanical properties of urea formaldehyde resins may be improved by incorporating therein polyvinyl alcohol. The polyvinyl alcohol may be incorporated during pre-mixing, mid mixing, and/or post mixing of the resin components. Resins prepared using polyvinyl alcohol are particularly desirable in articles requiring improved mechanical strength and water resistance, as compared to similar resins prepared without the polyvinyl alcohol such as shingles.
脲甲醛树脂的机械性质可以通过向其中引入聚乙烯醇而改善。可以在树脂组分的预混合、中间混合和/或后混合期间引入聚乙烯醇。在与没有聚乙烯醇制备的类似树脂相比要求改善的机械强度和耐水性的制品，如顶板中特别希望使用聚乙烯醇制备的树脂。 |
