Embodiment 1

[0039] A vermiculite calcium silicate composite board capable of releasing negative oxygen ions, the composite board is a layer of vermiculite tourmaline mixed layer on a common calcium silicate board, the vermiculite tourmaline mixed layer is made of expanded vermiculite The stone, tourmaline and adhesive are mixed according to the weight ratio (10% of expanded vermiculite, 5% of tourmaline, and 85% of adhesive), and the mixed layer of vermiculite and tourmaline obtained is distributed on ordinary silicon Calcium Acid Board.

[0040] The specific steps of the secondary distributing method are as follows:

[0041] ① Use the batching system to make expanded vermiculite, tourmaline, adhesive, etc. into a uniform mixture according to the ratio;

[0042] ② After the ordinary calcium silicate board is formed by the head roller, a layer of the mixture in ① with thickness requirements is applied on the surface by coating process

[0043] ③Squeeze by cold press; maintain and dry.

Abstract

The invention relates to a vermiculite and calcium silicate composite board capable of releasing negative oxygen ions. A vermiculite and tourmaline mixed layer is spread on an ordinary calcium silicate board to form the composite board. The vermiculite and tourmaline mixed layer is made by mixing by weight: expanded vermiculite 10-40%, tourmaline 0-5% and an adhesive 60-90%, and the composite board is made by spreading the vermiculite and tourmaline mixed layer on the ordinary calcium silicate board by secondary distribution prior to pressing, curing and drying. Compared with the prior art, the composite board has functional features such as the ability to release negative ions in long time and to purify pollutants such as formaldehyde, good moisture absorbing and releasing performance, good breathability, fire protection, acoustic insulation, corrosion resistance, mold resistance and low cost, is a green ecological building product and has a promising market prospect.

Description

technical field [0001] The invention relates to a green ecological building material, in particular to a vermiculite calcium silicate composite board capable of releasing negative oxygen ions. Background technique [0002] Calcium silicate board is a new type of building material with stable performance invented by OCDG Company of the United States. It was popularized and developed in developed countries in the 1970s. Japan and the United States are the most common countries where this material is used. After more than 30 years of application, it has proven to be a durable and reliable building material. Calcium silicate board is made of siliceous materials (quartz powder, diatomaceous earth, etc.), calcium materials (cement, lime, etc.), reinforcing fibers (pulp fiber, glass fiber, asbestos, etc.) through pulping, billeting, and steam curing. , surface sanding and other processes made of lightweight panels. It has the characteristics of light weight, high strength, fire...
