Abstract
An additive comprising a phosphazene compound that has at least two reactive functional groups and at least one capping functional group bonded to phosphorus atoms of the phosphazene compound. One of the at least two reactive functional groups is configured to react with cellulose and the other of the at least two reactive functional groups is configured to react with a resin, such as an amine resin or a polycarboxylic acid resin. The at least one capping functional group is selected from the group consisting of a short chain ether group, an alkoxy group, and an aryloxy group. Also disclosed are an additive-resin admixture, a method of treating a wood product, and a wood product.
Claims22
An additive, comprising:
- at least two reactive functional groups and at least one capping functional group bonded to phosphorus atoms of a first phosphazene compound, wherein one of the at least two reactive functional groups is configured to react with cellulose and the other of the at least two reactive functional groups is configured to react with a resin, and wherein the at least one capping functional group is selected from the group consisting of a short chain ether group, an alkoxy group, and an aryloxy group.
An additive-resin admixture, comprising:
- an additive admixed with a resin, the additive comprising a phosphazene compound comprising at least two reactive functional groups and at least one capping functional group bonded to phosphorus atoms of the phosphazene compound, the at least one reactive functional group configured to react with cellulose, and the at least one capping functional group selected from the group consisting of a short chain ether group, an alkoxy group, and an aryloxy group.
A method of treating a wood product, comprising:
- mixing an additive with a resin to form an additive-resin admixture, the additive comprising at least two reactive functional groups and at least one capping functional group bonded to phosphorus atoms of a phosphazene compound, the at least two reactive functional groups configured to react with at least one of cellulose and the resin, and the at least one capping functional group selected from the group consisting of a short chain ether group, an alkoxy group, and an aryloxy group;
- and
- impregnating the additive-resin admixture into a wood product.
A wood product, comprising:
- a phosphazene compound bonded to cellulose through a first phosphorus atom of the phosphazene compound and to a resin through a second phosphorus atom of the phosphazene compound, the phosphazene compound comprising at least one capping functional group bonded to at least one phosphorus atom of the phosphazene compound, the at least one capping functional group selected from the group consisting of a short chain ether group, an alkoxy group, and an aryloxy group.
