Embodiment 1

[0044] 1. Preparation of paraffin wax emulsion-borate composite modifier

[0045]Take 135g of No. 54 semi-refined paraffin wax (melting point 54-56°C), melt it at 80°C, and after the solid paraffin is completely dissolved, add 15g of sorbitan fatty acid ester span80 and 35g of polyoxyethylene to dehydrate in turn while stirring Sorbitol monolaurate tween80, 20g sodium stearate, 20g stearic acid and 20g n-amyl alcohol, then stirred at 3000rpm for 30min at 80°C, and added tetraboric acid decahydrate with a concentration of 15% while stirring Sodium aqueous solution 805g, the primary emulsion was prepared. The primary emulsion is subjected to high-pressure homogenization by a high-pressure homogenizer, the homogenization pressure is 40 MPa, and the number of homogenization is 2 times, and finally a paraffin wax emulsion-borate composite modifier is obtained.

Abstract

The invention discloses a paraffin emulsion-borate compound modifier which comprises the following components in parts by weight: 1-2000 parts of solid paraffin of which the melting point is 48-64 DEG C, 1-500 parts of a nonionic surfactant, 1-200 parts of an anion surfactant, 1-200 parts of a cosurfactant, 1-200 parts of fatty acid, 1-2000 parts of borate and 1-10,000 parts of water. The paraffin emulsion-borate compound modifier disclosed by the invention is utilized to perform pretreatment on high-heat treatment material so as to improve the mechanical property, the dimensional stability and the property of preventing termites of the high-heat treatment material.

Description

technical field [0001] The invention relates to a composite modifier, a preparation method thereof, and an application thereof in modifying high-temperature heat treatment materials. Background technique [0002] Wood is a kind of green material formed by the natural growth of trees in nature, and it is a huge reserve of biomass in forest ecosystems. As an industrial and domestic material, wood is closely related to national economic construction and human life, and has many excellent qualities, such as high strength-to-weight ratio, low processing energy consumption, low environmental pollution, recyclable utilization, and good environmental coordination. Wood is mainly composed of cellulose, hemicellulose and lignin, so it contains a large number of hydrophilic hydroxyl groups, which is easy to absorb water. The change of wood moisture content during use leads to some defects in wood, such as dry shrinkage and wet expansion, irregular size Stable; perishable, poor biologi...
