Abstract
Official abstract text for this publication.
A polyacetal resin composition which exhibits resistance to hot water, and contains 100 parts by mass of a polyacetal resin, 1 to 100 parts by mass, inclusive, of glass fibers subjected to a surface treatment with a blocked isocyanate compound and an aminosilane coupling agent, and 0.001 to 1.0 parts by mass, inclusive, of boric acid.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polyacetal resin composition, comprising: 100 parts by mass of a polyacetal resin (A); 10 parts by mass or more and 55 parts by mass or less of a glass fiber (B) surface-treated with a blocked polyfunctional isocyanate compound and an aminoalkoxysilane coupling agent; and 0.001 parts by mass or more and 1.0 part by mass or less of boric acid (C). 2. The polyacetal resin composition according to claim 1 , wherein the glass fiber (B) is a glass fiber surface-treated with a blocked polyfunctional isocyanate compound, an aminoalkoxysilane coupling agent, and a polyurethane resin. 3. The polyacetal resin composition according to claim 1 , wherein the boric acid (C) is orthoboric acid. 4. The polyacetal resin composition according to claim 1 , further comprising 0.002 parts by mass or more and 10 parts by mass or less of a triazine derivative having a nitrogen-containing functional group. 5. The polyacetal resin composition according to claim 2 , wherein the boric acid (C) is orthoboric acid. 6. The polyacetal resin composition according to claim 2 , further comprising 0.002 parts by mass or more and 10 parts by mass or less of a triazine derivative having a nitrogen-containing functional group. 7. The polyacetal resin composition according to claim 3 , further comprising 0.002 parts by mass or more and 10 parts by mass or less of a triazine derivative having a nitrogen-containing functional group.
