Abstract

The invention provides a neutral silicone negative ion structure adhesive. The neutral silicone negative ion structure adhesive is prepared from the following components in part by weight: 10-40 partsof organic hydroxyl silicone, 2-10 parts of methyl silicone, 5-20 parts of organic methyl ketone, 15-30 parts of calcium carbonate, 0.1-0.7 part of amino silane, 2-10 parts of fumed silica and 2-7 parts of negative ion wood flour; the negative ion wood flour is prepared from the following raw materials in proportion: 10-20 parts of banyan flour, 8-19 parts of modified starch, 8-18 parts of bambooand wood powder, 8-15 parts of glass fiber, 5-12 parts of plant fiber, 4-11 parts of coupling agent and 5-12 parts of hokutolite. The neutral silicone negative ion structure adhesive provided by theinvention can produce negative air ions and is suitable for the field of the environment-friendly home. The invention also provides a plywood comprising an elastic membrane layer, a non-woven fiber layer, a glass fiber reinforced plastic keel layer and a molding negative ion powder layer overlapped in sequence to produce the negative ions. The molding negative ion powder layer can be replaced to achieve ventiliation.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, and in particular relates to a neutral silicone negative ion structural glue, plywood and a preparation method. Background technique [0002] Neutral silicone structural adhesive is a neutral curing structural adhesive specially designed for structural bonding assembly in building curtain walls. It can be easily extruded and used under wide temperature conditions, and it can be cured into excellent, durable high modulus and high elastic silicone rubber by relying on the moisture in the air. The neutral silicone structural adhesives in the prior art are improved in elasticity and viscosity, but cannot generate negative ions. [0003] With people's increasing pursuit of health, the demand for negative ions is also increasing. By giving plywood the function of releasing negative ions, the requirements can be met to a certain extent and such problems can be alleviated. Pl...
