Abstract

Official abstract text for this publication.

A wood adhesive is provided. The wood adhesive includes a first agent and a second agent. The first agent includes a sodium carboxymethyl cellulose and a styrene-butadiene rubber polymer. The sodium carboxymethyl cellulose has a molecular weight between 15,000 and 500,000 and a degree of substitution of from 0.4 to 2.00 of the sodium salt. The second agent includes a polymeric quaternary amine.

First claim

Opening claim text (preview).

What is claimed is: 1. A wood adhesive, consisting of: a first agent, consisting of: a sodium carboxymethyl cellulose having a molecular weight between 15,000 and 500,000 and a degree of substitution of from 0.4 and 2.00 of the sodium salt; and a styrene-butadiene rubber polymer; and a second agent, consisting of: a polymeric quaternary amine and NaOH, wherein a ratio of the weight of the styrene-butadiene rubber polymer to the sum of weights of the sodium carboxymethyl cellulose and the polymeric quaternary amine is in the range from 0.05:1 to 1:0.1. 2. The wood adhesive according to claim 1 , wherein a weight ratio of the first agent to the second agent is in the range from 0.25:1 to 1:0.05. 3. The wood adhesive according to claim 1 , wherein a weight ratio of the first agent to the second agent is in the range from 0.7:1 to 1:0.2. 4. The wood adhesive according to claim 1 , wherein a weight ratio of the sodium carboxymethyl cellulose to the polymeric quaternary amine is in the range from 0.05:1 to 1:0.05. 5. The wood adhesive according to claim 1 , wherein the first agent further comprises water, and the sodium carboxymethyl cellulose and the styrene-butadiene rubber polymer exist in aqueous phase, and the second agent further comprises water, and the polymeric quaternary amine exists in aqueous phase. 6. The wood adhesive according to claim 1 , wherein the polymeric quaternary amine is formed by the reaction of polyamidoamine with epichlorohydrin. 7. The wood adhesive according to claim 1 , further comprising at least one of an inorganic substance and an organic filler. 8. The wood adhesive according to claim 7 , wherein the inorganic substance comprises flame retardant, and the organic filler comprises at least one of flour, starch and sawdust. 9. The wood adhesive according to claim 1 , wherein the styrene-butadiene rubber polymer comprises carboxylate anion (—COO − ).
